Charles,
are you saying that even if you
mpirun --mca pml ob1 ...
(e.g. force the ob1 component of the pml framework) the memory leak is
still present ?
As a side note, we strongly recommend to avoid
configure --with-FOO=/usr
instead
configure --with-FOO
should be used (otherwise you will end u
Posting this on UCX list.

Oops! We had a typo in yesterday's fix -- fixed:
https://github.com/open-mpi/ompi/pull/5847
Ralph also put double extra super protection to make triple sure that this
error can't happen again in:
https://github.com/open-mpi/ompi/pull/5846
Both of these should be in tonight's nightly s
It was originally for performance reasons, but this should be fixed at this
point. I am not aware of correctness problems.
However, let me try to clarify your question about: What do you precisely mean
by "MPI I/O on Lustre mounts without flock"? Was the Lustre filesystem mounted
without flock?
Is romio preferred over ompio on Lustre for performance or correctness?
If it's relevant, the context is MPI-IO on Lustre mounts without flock,
which ompio doesn't seem to require.
Thanks.

Please send Jeff and I the opal/mca/pmix/pmix4x/pmix/config.log again - we’ll
need to see why it isn’t building. The patch definitely is not in the v4.0
branch, but it should have been in master.
