Unfortunately, the number of processes for each test is hardcoded in the testlist files. There is no mechanism for filtering or dynamically modifying them. You could either maintain a custom patch to modify the testlist, or have a script applying a separate xfail list. An example of such xfail list that we used in our internal testing is in test/mpi/maint/jenkins/xfail.conf. If the custom patch solution won't work in your situation, please open an github issue describing your use case, and we can discuss to add a filtering option to the runtests script. -- Hui ________________________________ From: Max R.

Dechantsreiter <[email protected]> Subject: [mpich-discuss] MPICH Test Suite - limit number of processes I would like to limit the number of processes used by the MPICH Test Suite, which I run by "make testing" after building MPICH. I tried export MPITEST_PPNMAX=<n> # The maximum number of processes per node. but this had no apparent effect: some tests still ran using more than 4 processes, when I replaced <n> by 4. How could I restrict these tests to run with maximum 4 processes, for example? _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
