On-node Resource Management for Supercomputers
News Article, September 1, 2016 • Researchers at Sandia National Laboratories are designing an integrated approach to resource management on the supercomputer node. Increasingly complex DOE applications and associated libraries create the problem of too many software components competing for shared on-node resources – system memory and processor cores on which to execute. Our resource management...
