| - | These pages show the results of performance tests for different dynamo codes on the [[https://www.tacc.utexas.edu/user-services/user-guides/stampede-user-guide|TACC XSEDE Stampede system]]. | ||
| - | To clarify terminology, here are some definitions of terms used in the measurements: | ||
| - | * Node: On Stampede, each node contains //2 Xeon E5-2680// processors, each with 8 cores, for a total of 16 cores per node. Each node also has //32GB 8x4G 4 channels DDR3-1600MHz// of memory, | ||
| - | * Core: A single core in a processor. | ||
| - | * MPI processes: | ||
| - | * Thread: An OpenMP thread. Unless otherwise specified processor thread affinity is not enabled. | ||
| - | * SU: Service unit, a unit of usage accounting equal to //#cores x #hours//. Usage is billed by the node, so using 8 of 16 cores in a node for 1 hour will be recorded as 16 SUs rather than 8 SUs. | ||
| - | |||
| - | All timings are measured in terms of wall time unless otherwise specified. They are measured using ''MPI_Wtime()'' (If program does not use MPI, ''system_clock(itime, irate, imax)'' is used). The time for one step is determined by taking the mean of the elapsed time for 100 time steps. | ||
