As reported on HPC Wire, NASA and a team of federal, university and vendor partners will be demonstrating significant local- and wide-area file transfers using 40- and 100-gigabit-per-second (Gbps) network technologies. The venue, SC10, is the international conference on high-performance computing, networking, storage and analysis. With these demonstrations, NASA hopes to determine optimal “tuning parameter” settings to obtain maximum user throughput performance. The NASA team consists of the NASA Center for Climate Simulation’s Advanced Development Team from GSFC and the NASA Research and Education Network Team from Ames Research Center, as well as HECN.
“‘For supercomputing applications such as climate modeling, users need to be able to copy data files that are expanding at an ever-increasing rate,’ said J. Patrick (Pat) Gary, project manager for GSFC’s High-End Computer Networking (HECN) Team. ‘A current case is the International Governmental Panel on Climate Change’s Fifth Assessment Report, for which modeling centers will produce tens of petabytes of data that need to be available at multiple sites around the globe. To tackle such challenges, we are purposefully working with files as large as 128 gigabytes using a variety of file-copying applications.'”
