We run an empirical study to determine the performance attainable
using scalable locality on a distributed shared memory system.
We utilize the PLUTO automatic parallelizer and locality optimizer
on a one-dimensional Jacobi stencil with a distributed shared memory
system provided by Intel’s Cluster OpenMP on commodity hardware.
Unlike earlier works which base performance concerns on tile size, we
discover tile sizes are less crucial, and instead threading issues and
cache interference need particular attention. On our 56 processor cluster
of 14 quad-core machines, with preliminary single-level tiling we
are able to realize 121.3 GFLOPS, or 63% of linear speedup. Our data
suggest that adding further cores would increase performance linearly. |
