Science Highlights
 
Can deep learning yield more accurate extreme weather forecasts?
 
XSEDE systems support pattern recognition-based extreme weather prediction
 
 
Forecasting the weather patterns that cause extreme weather events is challenging despite decades of efforts and advances in numerical weather prediction (NWP). Modern forecasts use mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Even with the increasing power of today's supercomputers, the forecasting skill of numerical weather models extends to only about six days, although there is some dependence on location, season, and type of weather pattern.
 
Two XSEDE researchers recently introduced a data-driven framework that: 1) formulates extreme weather prediction as a pattern recognition problem, and 2) employs state-of-the-art deep learning techniques. The advantage of this data-driven framework is that once trained on observational and/or high-resolution numerical model data, it can provide relatively accurate predictions at very little computational cost, which can augment and guide other NWP efforts by providing early warnings.

Simulations reveal galaxy clusters details
 
XSEDE-allocated supercomputers used to probe galaxy clusters
 
 
Inspired by the science fiction of the spacefaring Romulans of Star Trek, astrophysicists have used XSEDE-allocated supercomputers to develop cosmological computer simulations called RomulusC, where the ‘C' stands for galaxy cluster. With a focus on black hole physics, RomulusC has produced some of the highest resolution simulations ever of galaxy clusters, which can contain hundreds or even thousands of galaxies.
 
On Star Trek, the Romulans powered their spaceships with an artificial black hole. In reality, it turns out that black holes can drive the formation of stars and the evolution of whole galaxies. And this galaxy cluster work is helping scientists map the unknown universe.

XSEDE powers undergraduate astronomy research
 
Two undergraduate physics students present research at AAS 235
 
 
For more than 40 years, computer simulations have provided spectacular views of galaxies. To foster future research on this important aspect of astrophysics, a physics professor at Reed College has been guiding two undergraduate students on the use of supercomputers to create such simulations.
 
These students had their simulations presented at the  235 Meeting of the American Astronomical Society  earlier this month. They first learned to use  ChaNGa , which is a publicly available N-body simulation code developed at the University of Washington in collaboration with the University of Illinois at Urbana-Champaign. Because their ChaNGa simulations required parallel computation on hundreds of processors, they were able to use SDSC's Comet , thanks in part to an allocation from XSEDE.

Program Announcements
 
XSEDE EMPOWER now accepting undergraduate applicants for summer 2020 internships
 
 
Do you know an undergraduate interested in computation, conducting their own research, and making connections within our community? Tell them about   XSEDE EMPOWER ( E xpert  M entoring  P roducing  O pportunities for  W ork,  E ducation, and  R esearch), an internship program where undergraduates have the chance to participate in actual XSEDE activities, like computational research and education in all fields of study, data analytics research and education, networking, system maintenance and support, and visualization. Undergraduate students at any U.S. degree-granting institution are welcome to apply. No prior experience necessary.  The deadline to apply for Summer 2020 internships is February 28, 2020.
 
 
Check out this video to learn more about XSEDE EMPOWER and what two recent interns have to say about the program.
 
Community Announcements
 
Trusted CI to launch Trustworthy Data Working Group
Trusted CI is launching a new Trustworthy Data Working Group. The group will survey science projects to learn about data security concerns and practices, and will publish their survey results and analysis over the coming year. Participation in the working group is open to all.
 
To participate:
  • Visit https://trustedci.org/2020-trustworthy-data to comment on the working group's draft charter and join the mailing list.
  • Complete this poll to help the team select a weekly time for a working group call.
  • Respond to Trusted CI's survey when it is announced and comment on the draft report when it is published.
 
 
PEARC20 currently accepting conference proposals
PEARC20 is now accepting conference proposal submissions. Deadlines are as follows:
 
February 17

  • Abstracts due for Lightning Talk submissions
 
February 24
  • Student technology track full paper submissions due
 
Additional information, including the full list of deadlines may be found at the link below.
 
 
Apply for SGCI's student-focused programs
The Science Gateways Community Institute's  student-focused programs   offer the experience that students need for pursuing a career building or using science gateways.  Apply by April 30, 2020 , for the following opportunities:
  • Four-week Coding Institute for undergraduate students June 1-26, 2020, at Elizabeth City State University
  • Eight-week internships at various host sites for students at any level interested in developing their gateway development skills (gateway project teams interested in hosting an intern, please apply by May 29, 2020.)
The  Young Professional of the Year  award acknowledges young professionals under the age of 40 for notable achievement in the advancement of science gateways.  Apply or nominate by August 6. 2020.
 
 
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.
