2.2 Performance Tests

2.2.1 Micro-benchmarks

The Micro-benchmark directory contains programs to measure latency of data transfer calls and collective calls in OpenSHMEM. Performance tests measure the time taken for a OpenSHMEM call by finding the average over 10000 calls.

i. put_performance ii. get_performance iii. broadcast_performance
iv. barrier_performance
v. collects_performance

3. Running Tests

Edit the Makefile or export values, such that they use the appropriate compiler, (SHMEM_FLAGS), run command (RUNCMD), run options (RUNOPT), command line options to control execution environment (NPROCOPT), NPROC (this parameter decides the number of PEs, default value is 2). To compile use 'make all' and to execute use 'make run'.

Done testing. Summary:

• 50/50 Passed.
• 0/50 Failed.

If the test says 'Passed' then the routines that are being tested behave in accordance with OpenSHMEM Specification 1.2 and the result produced (if applicable) is correct.
