Building instructions:
* Open the Makefile and fix the following variables:
* PMIX_BASE should point to the directory where PMIx is installed.
If you don't want to test PMIx - remove pmix from the list of "all" targets.
* PMI2_BASE should point to the directory where SLURM is installed.
If you don't want to test PMI2 - remove pmi2 from the list of "all" targets.
* run `make`.
The follwoing files (or one of them) will be built as the result:
* pmix_intra_perf - that is for testing pmix performance
- pmi2_intra_perf - for testing pmi2 performance
Running instructions:
The following options are supported by both of the binaries:
-s, --key-size=<size> size of the key's submitted (default is 100 * sizeof(int) bytes)
-c, --key-count=<size> number of keys submitted to local and remote parts (default is 10)
-d, --direct-modex use direct modex if available
--debug force all processes to print out the timings themself
You can run it directly with your favorite launcher (mpirun/srun), just
make sure that both MPI and PMIx libraries are visible for the loader.
For PMIx testing "convenience" there is a `run.sh` script that can be used to
ensure that environment is set properly (not a production grade so may not work
for all environments). To use it open it and fix:
- OMPI_BASE to point to your MPI installation
- PMIX_LIB to point to your PMIx installation
If you are running inside the supported batch system you shoud be fine to
just run fixed `run.sh` with the first argument defining how many processes
needs to be launched and all other parameters will be passed to the performance
tool. For example:
$ ./run.sh 10 -d
