Kenneth,

If I were to run these examples outside of the provided scripts, how would I used these environment variables? There seems to be a multitude of ways environment variables can be specified.

Thanks Mike

Hi Mike,

Those testlist files are interpreted by the mpich/test/mpi/runtests script to set actual MPICH/Hydra envvars.

In the file testlist (i.e rma directory) you have what looks like environment variables like timeLimit=600, mpiversion=3.0 listed by the names of the tests (as well as the number of processors to pass to mpirun). How are these values used? I looked in the mtest.c routines and there are environment variables (i.e. MPITEST_DEBUG, MPITEST_VERBOSE) that you read to control execution of the tests, but I don't see the ones listed here.

Thanks Mike _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
