A plenary panel at the recent XSEDE15 conference in St. Louis, MO, highlighted the broad spectrum of computing resources the U.S. National Science Foundation (NSF) has made available in recent years.
"I don't think there has been a time previously when NSF funded the diversity of systems that are available today," said panelist Craig Stewart, associate dean of research technologies at Indiana University.
Among the systems discussed were Wrangler, a data-intensive system that includes hardware at the Texas Advanced Computing Center (TACC) and Indiana University, and Comet, a computing resource focused on small and medium jobs that entered production in May. Mike Norman, director of the San Diego Supercomputer Center, says Comet was inspired by data from 2012 that showed the overwhelming majority of jobs run on XSEDE resources used fewer than 2,000 cores and 30 percent of jobs used just one core.
Other systems discussed by the panel include the upcoming Jetstream cloud system, with hardware located at Indiana University and TACC, which is expected to go into production early next year. Also expected to go into product next year is Bridges, a data-centric system that will be located at the Pittsburgh Supercomputing Center.
Panelists also discussed the Chameleon and CloudLab testbeds, which are used for research on cloud computing systems.
