[mvapich-discuss] clog2TOslog2 fails on MPI_Test

[Anthony Chan]

What error message did clog2TOslog2 produce ?

If I recall correctly, mvapich2 1.4 made some MPI calls in
the implementation of some communicator creation calls that
casued logging to fail. But I don't recall MPI_Test has such
problem.

The error has since been fixed in 1.4.1.  You may want
to try newer version of mvapich2 to see the problem disappear.

If not, we need to do some more debugging to find out what went wrong.

PS. You could compile MPE for OpenMPI, see the mpe2/INSTALL if you
    really need to go that route.
