Towards the contention aware scheduling in HPC cluster environment
Sergey Blagodurov, Alexandra Fedorova · Journal of Physics Conference Series · 2012
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 shared caches, memory buses, memory controllers and memory domains). The shared resource 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. The goal of this work is the design, implementation and evaluation of a virtualized HPC cluster framework that is contention aware.
