Optimizing Shared Resource Contention in HPC Clusters

SESSION: Research Poster Reception

EVENT TYPE: Posters, Electronic Posters, and Education Posters

TIME: 5:15PM - 7:00PM

AUTHOR(S):Sergey Blagodurov, Alexandra Fedorova

ROOM:Mile High Pre-Function

Contention for shared resources in High Performance Computing (HPC) clusters occurs when jobs are concurrently executing on the same multicore node (there is a contention for allocated CPU time, shared caches, memory bus, memory controllers, etc). This contention incurs severe degradation to workload performance and stability and hence must be addressed. The state-of-the-art HPC clusters, however, are not contention-aware, with no virtualization supported to mitigate the contention effects through live job migration. The goal of this work is the design, implementation and evaluation of a virtualized HPC scheduling framework that is contention aware.
