Abstract
In this paper, we investigate the feasibility and benefits of resource overcommitment for compute intensive HPC applications in virtualized systems. We focus on overcommitting the CPU resource of a virtualized system for shared memory multi-threaded applications. We first study the behavior of HPC applications in a dedicated configuration where the resources are not overcommitted and not shared with other applications. Second, we evaluate the performance of the applications in a resource overcommitted configuration where the resources are overcommitted and shared with other applications. At last, we discuss issues toward modeling the performance of a resource overcommitted system. The performance modeling will help us utilize the system efficiently.
