Great. I will try the 3.0.x version to see how it goes. On a side note, I did manage to run EPW without getting memory leaks using openmpi-1.8.8 and gcc-4.8.5. These are the tools that apparently worked when the code was developed as seen on their Test Farm (http://epw.org.uk/Main/TestFarm).

However, our nightly snapshots of the 3.0.x branch are available for download. These are not official releases, but they are great for getting users to test what will eventually become an official release (i.e., 3.0.1) to see if particular bugs have been fixed. This is one of the benefits of open source. :-) Here's where the 3.0.1 nightly snapshots are available for download: https://www.open-mpi.org/nightly/v3.0.x/ They are organized by date.

So I thought it may take a while for the 3.0.1 to become available. Or did I miss something?

A workaround is to use ROM-IO instead of ompio, you can achieve this with mpirun —mca io ^ompio ... (FWIW 1.10 series use ROM-IO by default, so there is no leak out of the box) IIRC, a possible (and ugly) workaround for the compilation issue is to configure —with-ucx=/usr ... That being said, you should really upgrade to a supported version of Open MPI as previously suggested Cheers, Gilles On Saturday, January 6, 2018, Jeff Squyres (jsquyres) <jsquy...@cisco.com<mailto:jsquy...@cisco.com>> wrote: You can still give Open MPI 2.1.1 a try. It should be source compatible with EPW. Hopefully the behavior is close enough that it should work. If not, please encourage the EPW developers to upgrade. v3.0.x is the current stable series; v1.10.x is ancient.

On the EPW website (http://epw.org.uk/Main/DownloadAndInstall), it is stated that: Compatibility of EPW EPW is tested and should work on the following compilers and libraries: • gcc640 serial • gcc640 + openmpi-1.10.7 • intel 12 + openmpi-1.10.7 • intel 17 + impi • PGI 17 + mvapich2.3 EPW is know to have the following incompatibilities with: • openmpi 2.0.2 (but likely on all the 2.x.x version): Works but memory leak. If you open and close a file a lot of times with openmpi 2.0.2, the memory increase linearly with the number of times the file is open. So I am hoping to avoid the 2.x.x series and use the 1.10.7 version suggested by the EPW developers. However, it appears that this is not possible.

The fix was applied to the v2.1.x series, and a snapshot tarball containing the fix is available here (generally just take the latest tarball): https://www.open-mpi.org/nightly/v2.x/ The fix is still pending for the v3.0.x and v3.1.x series (i.e., there are pending pull requests that haven't been merged yet, so the nightly snapshots for the v3.0.x and v3.1.x branches do not yet contain this fix).
