Shows the wall clock run times of various jobs on Stampede as different combinations of MPI processes and OMP threads are allocated to each CPU socket on each node. This was done to show how socket affinity effects performance. The label on each bar lists the cluster name, the total number of cores used for that job, whether its hybrid or MPI, the number of MPI processes per node, and the number of OMP threads per MPI process. Each job was run using tacc_affinity and was compiled using the Intel 15.0.2 compilers with the –O3 option. All of the jobs run for this figure were ns = 10 nl = 10 ng = 10 nx = 240 ny = 05 and time = 120 s.
