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.
