Science Highlights
 
XSEDE supercomputer simulations aid in solving boron carbide mystery
 
Novel research findings assist in advancing future military armor
 
Boron carbide is one of the hardest materials on earth, yet it's also very lightweight, which explains why it has been used in making vehicle armor and body protection for soldiers. Building upon decades of research on how to make boron carbide even more efficient, an engineering team at the University of Florida has been conducting supercomputer simulations to better understand the nanoscale deformation mechanisms of this important material, which may provide insight into better protective mechanisms for vehicle and soldier armor after further testing and development.
 
Image Caption: The longstanding mystery: The Raman spectra for virgin boron carbide (dashed, purple) compared to the amorphized form of the material (green) indicates significant differences in the two forms of the material. Inset shows proposed mechanistic model for formation of amorphized regions within crystalline material. Supercomputer simulations by a University of Florida team are providing clues to understand how nanoscale deformations contribute to changes in the material's properties. Credit: High-Pressure Deformation and Amorphization in Boron Carbide in the Journal of Applied Physics (2019).
 
Program Announcements
 
Did you know? XSEDE offers digital badges to recognize competencies, promote training
 
 
From the Boy and Girl Scouts, to PADI diving instruction, to more recently popular geo-location games, badges are being successfully used to set goals, represent achievements, and communicate success in many contexts.
 
Put simply, a digital badge is an online representation of a skill you've earned.
 
XSEDE provides a large number of training opportunities for potential and existing users of its resources as well as staff members, and awards badges to learners who demonstrate competency in topics relevant to the use of XSEDE resources. Topics covered include an array of HPC skills and new technologies in both traditional and non-traditional HPC disciplines, with the end-goal of enabling learners to refine their skills and gain the competencies they need to be effective HPC researchers and practitioners.
 
 
XSEDE Cyberinfrastructure Integration Updates
 
 
XSEDE's User Requirements Evaluation and Prioritization (UREP) team completed the November 2019 Use Case Review and identified the two most important XSEDE cyberinfrastructure priorities as: documenting how to run containers on XSEDE resources, and improving automated security testing and consulting for XSEDE service operators. A report showing all the UREP established priorities for recently proposed use cases is available on the Research Software Portal ( here ).

SGCI announces 2020 Gateway Focus Weeks
 
 
Looking to build a sustainability plan for your gateway? Planning to write your next funding proposal?
 
The Science Gateways Community Institute offers two Focus Weeks per year. Gateway Focus Week is a five-day intensive workshop that has been carefully designed to benefit teams who want to ensure the sustainability of their gateway proj ects.
 
The 2020 sessions are: 
  • June 1-5, Columbia University, New York, NY (apply by March 27). 
  • Nov. 30-Dec.4, San Diego Supercomputer Center, La Jolla, CA (apply by Sept. 25).
 
During Focus Week, teams engage in hands-on activities that help them articulate the value of their work to key stakeholders. Participating teams produce a strong development, operations, and sustainability plan with a corresponding pitch deck that includes actionable goals. By working closely across teams, participants have the opportunity to learn from each other's experiences and challenges. Focus Week attendees leave with a flexible toolkit that can be used as their projects continue to mature.
 
Focus Week is subsidized by the National Science Foundation. This allows you to attend what would otherwise be a $2,500 per team event at no cost other than travel, hotel, and a few meals.

Interstellar iron found hiding in plain sight
 
XSEDE resources used to discover new class of molecules
 
 
Iron, one of the most abundant elements in the universe, is most typically found in gaseous form in stars such as the sun and in a more condensed form in planets such as Earth.
 
Iron in interstellar environments should also be common, but surprisingly, astrophysicists detect only low levels of the gaseous kind. This implies to researchers that the missing iron exists in some kind of solid form or molecular state, yet identifying its hiding place has remained elusive.
 
A team of cosmo-chemists at Arizona State University, with support from the W.M. Keck Foundation and access to XSEDE-allocated resources, now claims that the mystery may be simpler than it seems. The iron isn't really missing, they say. Instead, it's hiding in plain sight. The iron is believed to have combined with carbon molecules to form molecular chains called iron pseudocarbynes. The spectra of these chains are almost identical with the much more common chains of carbon atoms, long known to be abundant in interstellar space.
 
 
Iron (Fe) pseudocarbynes are likely widespread in the interstellar medium, where extremely cold temperatures would lead carbon chains to condense on Fe clusters. Over eons, the formation of complex organic molecules would be facilitated from Fe pseudocarbynes. The model shows a hydrogen-capped carbon chain attached to an Fe13 cluster (iron atoms are shown as reddish brown, carbon is gray, hydrogen is light gray).

Supercomputer simulations help optimize floating wind farms
 
 
Over the past few years, offshore wind farms have emerged across the world as a viable source of energy. While these  powerful floating wind turbines  are typically more than 800 feet tall and can weigh some 50 tons or more, they reduce land-use concerns, access better offshore wind resources, and can generate more power than land wind turbine farms. However, they present a complex engineering design problem: how can they be optimized to operate in the uniquely challenging offshore environment?
 
With help from XSEDE, researchers from the University of Massachusetts Amherst and the National Renewable Energy Laboratory ( NREL) are advancing our knowledge of this issue.

A badge is a symbol or indicator of an accomplishment, skill, quality, or interest.

From the Boy and Girl Scouts, to PADI diving instruction, to more recently popular geo-location games, badges are being successfully used to set goals, represent achievements, and communicate success in many contexts.

Put simply, a digital badge is an online representation of a skill you've earned.

XSEDE provides a large number of training opportunities for potential and existing users of its resources as well as staff members.

Topics covered include an array of HPC skills and new technologies in both traditional and non-traditional HPC disciplines. The goal of this training is to enable learners to refine their skills and gain the competencies they need to be effective HPC researchers and practitioners.

XSEDE awards badges to learners who demonstrate competency in topics relevant to the use of XSEDE resources.

Sandie Kappes, a senior project coordinator and instructional designer at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign, led the Badge pilot program for XSEDE in 2015.

"This effort recognizes learner skill development from participation in a variety of XSEDE training opportunities," Kappes said.

One such training example is the OpenACC workshop provided by the Pittsburgh Supercomputing Center. In this workshop users learn how to use OpenACC compiler directives to take advantage of GPU resources available on XSEDE.

Three badges – beginner, intermediate, and advanced – are offered to recognize OpenACC skills. Although attending the workshop is recommended, anyone can attempt the assessments to earn any of the badges.

"The XSEDE OpenACC beginner badge is one of the most popular to date," Kappes said. "Another popular one is the Big Data badge."

Andreas Achazi is a postdoctoral researcher in computational chemistry from Germany. He simulates chemical reactions in silico instead of performing them in the lab. Achazi is starting to integrate machine learning into his research. So, he signed up for the XSEDE Big Data workshop to learn more about this field.

"It was a packed two-day workshop with introductory talks about scalable data analytics, machine learning, and hands-on exercises," Achazi said. "After the workshop we had two weeks of server access to continue training. To earn the intermediate badge, I had to finish quizzes and a practical task with the software that we used during the workshop."

XSEDE's badge site uses the Moodle open source learning management system to issue its badges. Moodle is a widely used, robust infrastructure  that  provides  a  variety  of  teaching  and  learning  tools and enables issuing of badges using the Open Badges standard.

The Open Badges Standard  is a technical framework for creating, issuing, and displaying badges. It's a specification used to attach metadata to a digital badge image detailing the accomplishment achieved and verifying the criteria for earning the badge and who issued it.

Open Badges are non-proprietary and can be issued and earned by anyone. XSEDE's badge earners can store their badges within the XSEDE Moodle site or another badge collection site such as badgr.io. They can then share them on social media sites or via email.

A learner's collection of badges can serve as a virtual resume for sharing their competencies with peers and potential employers.

Kappes and Jeff Sale, who is a learning technologist at the San Diego Supercomputer Center, work with XSEDE technical subject matter experts to determine the necessary skills for earning a badge. Assessments are then developed to enable measurement of these skills.

"Right now, we mostly conduct objective quizzes to determine if someone has these competencies," Kappes said. "Some of the badges may also include an exercise which requires submission of documentation to demonstrate a competency."

The quizzes enable automatic awarding of a badge whereas exercises require manual grading by an XSEDE staff member.

For future badge offerings, Kappes wants to explore a variety of assessment methods to determine which are most suitable and how best to implement them.

Novel research findings assist in advancing future military armor

 

The longstanding mystery: The Raman spectra for virgin boron carbide (dashed, purple) compared to the amorphized form of the material (green) indicates significant differences in the two forms of the material. Inset shows proposed mechanistic model for formation of amorphized regions within crystalline material. Supercomputer simulations by a University of Florida team are providing clues to understand how nanoscale deformations contribute to changes in the material's properties.  Credit: High-Pressure Deformation and Amorphization in Boron Carbide in the Journal of Applied Physics (2019) (DOI:10.1063/1.5091795)

 

Boron carbide is one of the hardest materials on earth yet also very lightweight, which explains why it has been used in making vehicle armor and body protection for soldiers. Building upon decades of research on how to make boron carbide even more efficient, an engineering team at the University of Florida has been conducting supercomputer simulations to better understand the nanoscale deformation mechanisms of this important material. 

The research, which primarily used the Comet supercomputer at the San Diego Supercomputer Center (SDSC) at UC San Diego along with the Stampede and Stampede2 systems at the Texas Advanced Computing Center (TACC), may provide insight into better protective mechanisms for vehicle and soldier armor after further testing and development.

The study was published last month in an article entitled High-Pressure Deformation and Amorphization in Boron Carbide in the Journal of Applied Physics. The supercomputer access was provided by a grant from the National Science Foundation's Extreme Science and Engineering Discovery Environment, or XSEDE.

"Our research provided new insights and an excellent way of analyzing the root cause of catastrophic failure at high pressure induced by high-velocity impacts," said University of Florida Professor Ghatu Subhash of Mechanical and Aerospace Engineering. "Although boron carbide has several desirable properties, under high-velocity projectile impacts it suffers from a deleterious phenomenon called amorphization, where its crystal structure collapses to a disordered state in nanometer-sized regions within the materials."

Amorphization is the precursor for cracks in the armor, which may cause catastrophic failure.

The researchers conducted large-scale and multi-scale modeling of icosahedral-boron rich solids, the class of crystallographic structure to which boron carbide belongs.

"Our simulations ran more than three times faster per core when we switched from local workstations to Comet, and today our knowledge pertaining to material behavior of icosahedral ceramics has been elevated to a level that is second to none," said Amnaya Awasthi, a postdoctoral researcher who co-authored the study.


 XSEDE-Allocated Supercomputer Models Provide Insight on Turbine Wakes

Over the past few years, offshore wind farms have emerged across the world as a viable source of energy.  While these powerful floating wind turbines are typically more than 800 feet tall and can weigh some 50 tons or more, they reduce land-use concerns, access better offshore wind resources, and can generate more power than land wind turbine farms. However, they present a complex engineering design problem: how can they be optimized to operate in the uniquely challenging offshore environment?

In a Journal of Physics: Conference Series paper published this summer called Large eddy simulations of floating offshore wind turbine wakes with coupled platform motion, researchers from the University of Massachusetts Amherst and the National Renewable Energy Laboratory (NREL) discussed their efforts to advance our knowledge of this issue. 

Specifically, the Comet supercomputer at the San Diego Supercomputer Center (SDSC) and the Stampede2 supercomputer at the Texas Advanced Computing Center (TACC) were used to perform simulations that showed how floating turbine wakes are very similar those of fixed-bottom turbines, except that floating turbine wakes are deflected upward and have slightly stronger turbulence at the edge of their wakes.

"We looked at how these wake effects can be accurately considered when designing floating offshore wind farms," said lead author and National Science Foundation (NSF) Graduate Research Fellow Hannah Johlas. "At about 20,000 computer processor hours (per run), these high-fidelity large eddy simulations are very computationally intensive and expensive, and as such, this research can only be performed using supercomputers."

The collaborative study aimed to better understand how the wake effects of large wind farm arrays decrease power output and reduce the lifespan of the turbines. Because of the growing prospect for floating wind farms, the researchers focused on the differences between floating turbine wakes and fixed turbine wakes.

The large eddy wind turbine simulations were completed with Comet and Stampede2 using the computational fluid dynamics software Simulator fOr Wind Farm Applications (SOWFA), coupled with the wind turbine modeling tool OpenFAST for the platform and turbine motion. The downstream wake characteristics of the floating platform were compared to equivalent fixed platform cases for different wind speeds, wave heights, wind-wave alignments, and turbine yaw angles.

Overall, the differences in wake shape between floating and fixed platforms were associated with mean platform displacements, while differences in turbulence were associated with time-varying platform motion. However, these observed wake differences between fixed and floating platforms were found to be quite small, especially for higher wind speeds and lower wave heights.

"With global-installed capacity of offshore wind increasing from 8.9 gigawatts in 2015 to 22.5 gigawatts in 2018, this research is becoming even more prevalent and now that we know more about how wakes behave for floating turbines, we will examine how those floating-turbine wakes affect downstream turbine power generation and structural loading," said Johlas, who has focused her Ph.D. in mechanical engineering at the University of Massachusetts at Amherst on this project.

"Comet and Stampede2's reliability and computing environment flexibility helped complete this research in a time-efficient manner," added Johlas. "As this research was funded by an NSF Graduate Research Fellowship, there were no funds available for purchasing supercomputing time, so access to XSEDE supercomputers really enabled this research to happen at all. Also, XSEDE's support team helped solve environment setup and file system usage issues for us."

Johlas' research group, led by PI David Schmidt, previously used XSEDE-allocated resources, including Comet and Stampede2, for several years.

"XSEDE makes available some of the most reliably useful high-performance computers available to university researchers in my field," she said. "Since the progress of my research directly depends upon reliable access to supercomputing time, resources such as XSEDE enable researchers like me to envision more accurate, more complex simulations than are possible when using lower-fidelity tools." 

The research was funded by an NSF Graduate Research Fellowship, grant #1451512. The project used the Extreme Science and Engineering Discovery Environment (XSEDE) program funded by NSF grant #ACI-1548562, as well as NREL computational resources sponsored by the Department of Energy's Office of Energy Efficiency and Renewable Energy.


Service Provider Forum

The national cyberinfrastructure ecosystem is powered by a broad set of Service Providers (SP). The XSEDE Federation primarily consists of SPs that are autonomous entities that agree to coordinate with XSEDE and each other to varying degrees. The XSEDE Federation may also include other non-service provider organizations.

Service Providers are projects or organizations that provide cyberinfrastructure (CI) services to the science and engineering community. In the US academic community, there is a rich diversity of SPs, spanning centers that are funded by NSF to operate large-scale resources for the national research community to universities that provide resources and services to their local researchers. The Service Provider Forum is intended to facilitate this ecosystem of SPs, thereby advancing the science and engineering researchers that rely on these cyberinfrastructure services. The SP Forum provides:

  • An open forum for discussion of topics of interest to the SP community.
  • A formal communication channel between the SP Forum members and the XSEDE project.

SPs are classified as being at a specific level by meeting a minimum set of conditions.They may meet additional conditions at their option, but classification at a specific level will be based on the stated required minimum conditions.

Briefly, Level 1 SPs meet all the XSEDE integration requirements and will explicitly share digital services with the broader community. Level 2 SPs make some digital services accessible via XSEDE and Level 3 SPs are the most loosely coupled; they will share the characteristics of their services via XSEDE, but need not make those services available beyond their local community. For more detailed descriptions, see the documents linked below.

Science Gateways for Developers and Operators

This page documents required and recommended steps for developers. For additional assistance, XSEDE provides Extended Consultation Support Services and community mailing lists to assist gateway developers and administrators.

Science Gateways can democratize access to the cyberinfrastructure that enables cutting-edge science

What is an XSEDE Science Gateway?

An XSEDE Science Gateway is a web or application portal that provides a graphical interface for executing applications and managing data on XSEDE and other resources. XSEDE science gateways are community services offered by XSEDE users to their communities; each gateway is associated with at least one active XSEDE allocation. For an overview of the steps a gateway provider must take to start an XSEDE Science Gateway, see the Gateways for PIs page.

See the Science Gateways Listing for a complete list of current operational gateways.

Science gateway developers and administrators may include PIs as well as their collaborators, staff, and students. The PI should add these team members to the XSEDE allocation; see Manage Users for more details. It is recommended that the allocation have at least one user with the Allocation Manager role, in addition to the PI.

Operations Checklist

  1. The PI obtains an XSEDE allocation.
  2. The PI adds developer and administrator team members to the allocation.
  3. Register the gateway.
  4. Request for a community account to be added to the allocation. The PI logs onto the XSEDE User Portal and selects "Community Accounts." from the My XSEDE tab.
  5. Add the XSEDE logo to the gateway. See https://www.xsede.org/web/guest/logos.
  6. Integrate the user counting scripts with the gateway's submission mechanism.
  7. Join the XSEDE gateway community mailing list (optional).

Building and Operating

Science gateways can be developed using many different frameworks and approaches. General issues include managing users, remotely executing and managing jobs on diverse XSEDE resources, tracking jobs, and moving data between XSEDE and the user environment. XSEDE specific issues include tracking users, monitoring resources, and tracking use of the gateway allocation. For a general overview of best practices for building and operating a science gateway, please see the material developed by the Science Gateways Community Institute, an independently funded XSEDE service provider. The Institute provides support for different frameworks that can be used to build science gateways.

XSEDE supports a wide range of gateways and does not require specific middleware; gateways can use team-developed middleware or third party provided middleware. Gateways that run jobs and access data on XSEDE resources may be hosted on the PI's local servers or directly on XSEDE resources that support persistent Web services, middleware, and databases; these include Bridges, Comet, and Jetstream.

For gateway teams that would like additional development assistance, XSEDE supports the integration of science gateways with XSEDE resources through Extended Collaborative Support Services (ECSS). ECSS support can be requested as part of an allocation request; PIs can add ECSS support to an existing allocation through a supplemental request.

Managing User Accounts

XSEDE science gateways are community provided applications. Gateway users are not required to have XSEDE accounts or allocations. XSEDE allows all users jobs to run on the gateway's community account instead. Gateways thus map their local user accounts to the gateway's single community account. XSEDE does require quarterly reporting of the number of unique users who executed jobs on XSEDE resources, as described below.

XSEDE Community Accounts

XSEDE allows science gateways that run applications on behalf of users to direct all submission requests to a gateway community user account. Designated gateway operators have direct shell access to their community account, but normal users do not. The community account simplifies administration of the gateway, since the gateway administrators have access to input and output files, logs, etc, for all their users, and users don't need to request individual gateway accounts.

A community account has the following characteristics:

  • Only a single community user account (i.e., a XSEDE username/password) is created.
  • The Science Gateway uses the single XSEDE community user account to launch jobs on XSEDE.
  • The gateway user running under the community account has privileges to run only a limited set of applications.

Requesting a Community Account: The PI or Allocation Manager with a registered gateway can request a community account by logging on to the XSEDE User Portal and selecting "Community Accounts." from the "My XSEDE" tab. Select community accounts on all allocated resources.

Accessing Community Accounts: Administrators access community accounts through SSH and SCP using the community account username and password that is provided with the account. Community accounts cannot be accessed from the XSEDE single sign on hub.

Community Accounts on Sites with Two-Factor Authentication: Some XSEDE resources, including Stampede and Wrangler, require two-factor authentication. Gateways can request exceptions to this policy for their community accounts by contacting XSEDE Help Desk. The gateway will need to provide the static IP addresses of the server or servers it uses to connect to the resource.

Unique Science Gateway User Accounts

It is the gateway developer's responsibility, as described below, to implement gateway logins or otherwise uniquely identify users in order to track usage. These accounts can be local to the gateway and do not need to correspond to user accounts on XSEDE. The gateway maps these accounts to the gateway's common community account.

Gateways may optionally choose to use XSEDE's OAuth2-based authentication process for authentication. This is a service provided by Globus Auth. ECSS consultants are available to assist with this integration.

The XSEDE Cyberinfrastructure Integration (XCI) team has completed writing and testing the document "User Authentication Service for XSEDE Science Gateways." This is an introduction to the user authentication service that XSEDE offers for science gateway developers and operators. This service provides a user "login" function so that gateway developers don't need to write their own login code or maintain user password databases.

Connecting to XSEDE Resources

The most common type of XSEDE science gateway allows users to run scientific applications on XSEDE computing resources through a browser interface. This section describes XSEDE policies and requirements for doing this.

Community Allocations

Gateways typically provide their users with a community-wide allocation acquired by the PI on behalf of the community. The gateway may implement internal restrictions on how much of this allocation a user can use.

If a user is consuming an excessive amount of resources, the gateway may require these "power users" to acquire their own allocations, either through the Startup or XRAC allocation process. After obtaining the allocation, the user adds the gateway community account to her/his allocation. The user's jobs still run under the community account, but the community account uses the user's, rather than the gateway PI's, allocation. This is implemented by adding the allocation string to the batch script. This is the standard -A option for the SLURM schedulers used by many XSEDE resources; see examples for Stampede, Comet, and Bridges. Gateway middleware providers may provide this service as a feature.

Interacting with HPC Resources

Science gateways that run jobs on behalf of their users submit them just like regular users. For XSEDE's HPC resources, this means using the local batch scheduler to submit jobs and monitor them. For an overview, see the XSEDE Getting Started Guide. Gateways execute scheduler commands remotely through SSH and use SCP for basic file transfer. Gateways may choose to work with third party middleware and gateway framework providers to do this efficiently. For more information on third party software providers, consult the Science Gateways Community Institute service provider web site.

XSEDE ECSS consultants can assist gateways with HPC integration.

XSEDE Resources for Gateway Hosting

XSEDE includes resources that have special Virtual Machine (VM) and related capabilities for gateways and similar persistent services. These resources are allocated through the standard XSEDE allocation mechanisms.

  • Bridges is designed for jobs that need large amounts of shared memory. It also has allocatable VMs that have access to Bridges' large shared file system. VM users can directly access scheduler command line tools to Bridge's computing resources inside their VMs.
  • Comet, like Bridges, is a computing cluster with co-located Virtual Machines. Users can also request entire, self-contained Virtual Clusters that can run both the gateway services and computing jobs.
  • Jetstream is an XSEDE cloud computing resource. Gateway users can get persistent VMs for use in gateway service hosting. They can also get multiple VMs configured as a Virtual Cluster with a private scheduler for running computing jobs.

Science Gateway Usage Metrics: Unique Users per Quarter

XSEDE requires all gateways to report the number of unique users per quarter who have executed jobs on XSEDE resources. This is a key metric that XSEDE in turn reports to the NSF. Compliance with this requirement justifies XSEDE's investment in the science gateway community. XSEDE collects this information through a simple API that is integrated into the job submission process. XSEDE ECSS consultants are available to assist gateway developers to do this.

Security and Accounting

XSEDE has specific security and accounting requirements and recommendations for connecting to its resources to optimize your gateway for prevention and triage of security incidents or inadvertent misuse.

Security and Accounting Requirements and Recommendations

The following security and accounting steps are required.

  • Required: Notify the XSEDE Help Desk immediately if you suspect the gateway or its community account may be compromised, or call the Help Desk at 1-866-907-2383.
  • Required: Keep Science Gateway contact info up to date on the Science Gateways Listing in case XSEDE staff should need to contact you. XSEDE reserves the right to disable a community account in the event of a security incident.
  • Required: Use the gateway_submit_attributes tool to submit gateway username with job.

Additional recommendations are as follows:

  • Collect Accounting Statistics
  • Maintain an audit trail (keep a gateway log)
  • Provide the ability to restrict job submissions on a per user basis
  • Safeguard and validate programs, scripts, and input
  • Protect user passwords on the gateway server and over the network
  • Do not use passwordless SSH keys.
  • Perform Risk and Vulnerability Assessment
  • Backup your gateway routinely
  • Develop an an incident response plan for your gateway; review and update it regularly
  • Put a contingency plan in place to prepare for a disaster or security event that could cause the total loss or lock down of the server
  • Monitor changes to critical system files such as SSH with tripwire or samhain (open source)
  • Make sure the OS and applications of your gateway service are properly patched - Run a vulnerability scanner against them such as nessus
  • Make use of community accounts rather than individual accounts

These are described in more detail below in separate sections. XSEDE ECSS support staff can assist with designing and implementing best practices. The Science Gateways Community Institute service provider also provides information on best practices.

What To Do In Case of a Security Incident

Whether a threat is confirmed or suspected, quick action and immediate communication with XSEDE Security Working Group is essential. Please contact the XSEDE Help Desk immediately at 1-866-907-2383.

Regional Champions

The Regional Champion Program is built upon the principles and goals of the XSEDE Champion Program. The Regional Champion network facilitates education and training opportunities for researchers, faculty, students and staff in their region that help them make effective use of local, regional and national digital resources and services. Additionally, the Regional Champion Program provides oversight and assistance in a predefined geographical region to ensure that all Champions in that region receive the information and assistance they require, as well as establish a bi-directional conduit between Champions in the region and the XSEDE champion staff, thus ensuring a more efficient dissemination of information, allowing finer grained support. Finally, the Regional Champions acts as a regional point of contact and coordination, to assist in scaling up the Champion program by working with the champion staff to coordinate and identify areas of opportunity for expanding outreach to the user community.

Regional Champions are coordinated by Jeff Pummill.

Iron (Fe) pseudocarbynes are likely widespread in the interstellar medium, where extremely cold temperatures would lead carbon chains to condense on Fe clusters. Over eons, the formation of complex organic molecules would be facilitated from Fe pseudocarbynes. The model shows a hydrogen-capped carbon chain attached to an Fe13 cluster (iron atoms are shown as reddish brown, carbon is gray, hydrogen is light gray).

XSEDE resources used to discover new class of molecules

Iron, which is largely known for steel manufacturing, is most typically found in gaseous form in stars such as the sun and in a more condensed form in planets such as Earth. Astrophysicists know that iron is one of the most abundant elements in the universe, after lightweight elements such as hydrogen, carbon, and oxygen.

Iron in interstellar environments should also be common, but astrophysicists detect only low levels of the gaseous kind. This implies to researchers that the missing iron exists in some kind of solid form or molecular state, yet identifying its hiding place has remained elusive.

A team of cosmo-chemists at Arizona State University, with support from the W.M. Keck Foundation, now claims that the mystery may be simpler than it seems. The iron isn't really missing, they say. Instead, it's hiding in plain sight. The iron is believed to have combined with carbon molecules to form molecular chains called iron pseudocarbynes. The spectra of these chains are almost identical with the much more common chains of carbon atoms, long known to be abundant in interstellar space.

The team used the National Science Foundation-funded Extreme Science and Discovery Environment (XSEDE)'s Comet supercomputer at the San Diego Supercomputer Center (SDSC), an Organized Research unit at the University of California San Diego, to validate their findings, published earlier this year in the Astrophysical Journal.

"We are proposing a new class of molecules that are likely to be widespread in the interstellar medium," said Pilarisetty Tarakeshwar, a research associate professor in ASU's School of Molecular Sciences. His co-authors, Peter Buseck and Frank Timmes, are both in ASU's School of Earth and Space Exploration; Buseck, an ASU regents professor, is also in the School of Molecular Sciences with Tarakeshwar.

The team examined how clusters containing only a few atoms of metallic iron might join with chains of carbon atoms to produce molecules combining both elements. Recent evidence obtained from stardust and meteorites indicates the widespread occurrence of clusters of iron atoms in the cosmos. In the extremely cold temperatures of interstellar space, these iron clusters act as deep-freeze particles, enabling carbon chains of various lengths to stick to them, thus producing different molecules from those that can occur during the gaseous phase of iron.

Said Tarakeshwar, "We used Comet to calculate what the spectra of these molecules would look like, and we found that they have spectroscopic signatures nearly identical to carbon-chain molecules without any iron." He added that because of this, "previous astrophysical observations could have overlooked these carbon-plus-iron molecules."

The researchers say this means that the missing iron in the interstellar medium is actually out in plain view but masquerading as common carbon-chain molecules.

"The calculations involving iron pseudocarbynes were computationally challenging because we had to optimize the geometries and calculate the spectroscopic properties of several open-shell systems," said Tarakeshwar. "The computational resources on Comet (including the software installed on it) were instrumental in enabling us to complete most preliminary calculations in a couple of months. The support of SDSC staff, especially Mahidhar Tatineni, was extremely valuable because many problems we encountered were expeditiously resolved as soon as we encountered them."

The new work may also solve another longstanding puzzle. Carbon chains with more than nine atoms are unstable, according to the research team. Yet observations have detected more complex carbon molecules in interstellar space. How nature builds these complex carbon molecules from simpler carbon molecules has been a longstanding mystery.

"Longer carbon chains are stabilized by the addition of iron clusters," said Buseck, noting that this opens a new pathway for building more complex molecules in space such as polyaromatic hydrocarbons, of which naphthalene — the main ingredient in mothballs — is a familiar example.

Said Timmes, "Our work provides new insights into bridging the yawning gap between molecules containing nine or fewer carbon atoms and complex molecules such as C60 buckminsterfullerene, better known as 'buckyballs.'"

Since its inception, computational chemistry has been extremely interdisciplinary. "Resources such as XSEDE, which are operational because of the shared expertise of several talented people, reinforce the idea that one can advance fundamental understanding and solve cutting-edge problems by using such resources
