Subject: MPICH 3.3.1 tests fail
To: <discuss@mpich.org>

I have built MPICH 3.3.1 on Ubuntu 18.04 with the gcc-7 compiler suite. (Build script is provided: build_mpich.) I have built with both --with-device=ch3:nemesis and --with-device=ch3:nemesis:ofi

with the same outcome in the make test. A dozen of the tests fail with timeouts.

I ran the test on an 8 processor Thinkstation but what would be beneficial is some sort of sense of what the test results should be. I've browsed the test results that you've posted but these appear to be summaries that conclude All Tests Passed, without individual timings for each test.

In any case, I would appreciate any guidance that you might be able to provide. I have provided the config files and the summary.junit.xml file. (On my machine the summary.xml file just reports that there is an error on line 9562.) The result of mpiexec -info is:

~/build/mpich-3.3.1/src/pm/hydra % ./mpiexec.hydra -info
