Video: Prologue O/S – Improving the Odds of Job Success

“When looking to buy a used car, you kick the tires, make sure the radio works, check underneath for leaks, etc. You should be just as careful when deciding which nodes to use to run job scripts. At the NASA Advanced Supercomputing Facility (NAS), our prologue and epilogue have grown almost into an extension of the O/S to make sure resources that are nominally capable of running jobs are, in fact, able to run the jobs. This presentation describes the issues and solutions used by the NAS for this purpose.”

Pleiades Supercomputer Moves Up the Ranks with Haswell

NASA reports that it’s newly upgraded Pleiades supercomputer ranks number 11 on the July 2015 TOP500 list of the most powerful supercomputers. And while the LINPACK computing power of Pleiades jumped nearly 21 percent, its ranking at number 5 on the new HPCG benchmark list reflects its ability to tackle real world applications.
