DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: System noise on commodity clusters significantly impacts=0Athe scalability of scientific applications. As the number of nodes in=0Aa cluster grows, this impact outweighs the benefits of the increased=0Asystem capability. In this work, we propose using Simultaneous=0AMulti-Threading (SMT) to mitigate system noise, and we=0Ademonstrate its effectiveness using Fixed Work Quantum (FWQ)=0Amicro-benchmarks. This technique relies on using the floating-point and=0Ainteger units of a core (shared SMT resources) for system processing=0Awhen an application is stalled waiting for an out-of-core operation. Unlike=0Acore-specialization, which dedicates a core for system processing, our=0Aapproach allows an application to use all cores of a node and=0Aproves significantly more effective in reducing system noise.
