DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: We examine task mapping algorithms for systems that allocate jobs non-contiguously, such as the Cray X series.  Several studies have shown that task=0Aplacement affects job running time for both contiguously and non-contiguously allocated jobs.  Our focus is on jobs with a stencil communication pattern.  We use experiments on a Cray XE to evaluate novel task mapping algorithms as well as some adapted to this setting.  This is done with the miniGhost miniApp which mimics the performance of CTH, a shock physics application.  Our strategies improve average running time by as much as 28% over a baseline strategy.
