mpi-testsuite currently reports
$ grep "^ok" /usr/share/mpi-testsuite/results/mpich/summary.tap | wc
28 300 1805
$ grep "^not ok" /usr/share/mpi-testsuite/results/mpich/summary.tap | wc
922 5526 33004
$ grep "^ok" /usr/share/mpi-testsuite/results/openmpi/summary.tap | wc
681 3565 21965
$ grep "^not ok" /usr/share/mpi-testsuite/results/openmpi/summary.tap | wc
237 1314 8780
Odd result, that set of "not ok" suggests mpich is the more buggy.
