PEARC17 to welcome HPC community

The annual XSEDE conference is transforming to an independent entity designed to unite the HPC and advanced digital research community. The Practice & Experience in Advanced Research Computing (PEARC) will welcome all who care about using advanced digital services for research at PEARC17 in New Orleans, July 9-13, 2017.  Read more >>

Illuminate the Renaissance

Most of us have heard about the Six Degrees of Kevin Bacon, based on the "six degrees of separation" concept, which posits that any two people on Earth are six or fewer acquaintance links apart. Now, there's a similar game in town: Who knew whom in Renaissance Britain? This is the question that the project Six Degrees of Francis Bacon" seeks to uncover. "We're leveraging 21st century computational methods in order to illuminate the past," said Christopher Warren, associate professor of English at Carnegie Mellon University.  Read more >>

Deep Insights from Surface Reactions

Things that happen on the surface are often given short shrift compared to what goes on inside. But when it comes to chemical reactions, what occurs on the surface can mean the difference between a working material and one that refuses to perform its duty. XSEDE awarded Tao Wei, a researcher at Lamar University, several million computing hours on Stampede from 2014-2016 to enable his work. He also uses several other supercomputers, including the Gordon and SuperMIC systems, to make progress on a variety of important problems.  Read more >>

Underground Bacteria

One of the most detailed genomic studies of any ecosystem to date has revealed an underground world of stunning microbial diversity, and added dozens of new branches to the tree of life. "The CIPRES Science Gateway and the Comet supercomputer were instrumental to our work," PI Jill Banfield said. "Considering the unprecedented size of our sequence datasets, we were unable to complete any runs for inferring trees on other servers." The CIPRES Science Gateway and Comet are available through XSEDE.  Read more >>

XCI Update

The XSEDE Community Infrastructure (XCI) team delivered the following noteworthy new or enhanced software capabilities: a new XSEDE Community Software Repository (XCSR) service and tool, an improved Karnak job start prediction service, an updated CILogon authentication service, and new XSEDE National Integration (XINIT) Toolkit images on Jetstream. XSEDE also started providing the Open Science Grid (OSG) a dedicated IGTF-accredited CILogon CA instance that provides the OSG community with a cost-effective solution for digital certificates.  Read more >>

More Power to Us

Recent drops in the cost of batteries have made it possible for commercial customers to smooth out their need for grid power, potentially saving money for everyone. Michael Fisher, working with faculty advisor Jay Apt at Carnegie Mellon University, used XSEDE resources to investigate the economics of "behind the meter" batteries for commercial users.  Read more >>

How to See Living Machines

Georgia State University researcher Ivaylo Ivanov, who is studying atomic-level detail of a vital molecular machine, the human pre-initiation complex (PIC): "I have been using XSEDE resources for more than 12 years now," Ivanov said. "Without the availability of XSEDE resources, all of our research would have been much more limited in terms of the systems that we can address. For us, XSEDE has been absolutely essential."  Read more >>

Big Transparent Checkpointing

A team of researchers led by Jiajun Cao, a PhD candidate in the College of Computer and Information Science (CCIS) at Northeastern University, recently completed what appears to be the largest known instance of transparent checkpointing. "These results show how [XSEDE]... can help scientists and developers improve the scalability and efficiency of their code on high performance computing clusters," says Jérôme Vienne, a research associate at TACC.  Read more >>

Making a Tough Call

XRAS gives users "one stop shopping" for requesting XSEDE-allocated resources, says Dave Hart, director of XSEDE's Resource Allocations Service and user services manager at the Computation and Information Systems Laboratory of the National Center for Atmospheric Research (NCAR). These resources are as diverse as TACC's massively parallel Stampede; SDSC's Comet cluster; Indiana University's/TACC's Jetstream cloud computing environment; and PSC's heterogeneous Bridges system, featuring extreme memory nodes. XSEDE also includes valuable human resources: an XSEDE-supported corps of computational experts available through the Extended Collaborative Support Service (ECSS).  Read more >>

Unearthing America's Rural History

Throughout the 1930s and 1940s, Roy Stryker served as the head of the Information Division for the Farm Security Administration. He sent out photographers to capture images depicting rural life for a photo-documentary project, consisting of 250,000 photos; about 175,000 of these are preserved in the Library of Congress. Stryker used photography to change public perception and even Congressional perception of what was needed to alleviate the dire situation of farmers post-Dust Bowl and post-Great Depression. Whether or not you would consider this to be propaganda, it was certainly a media strategy which had significant impacts on our history. Now, with the help of XSEDE, the full stories can be told.  Read more >>
