Follow-up Comment #4, task #15737 (project reproduce):

It seems that more work is still needed to compile openmpi to use libraries
fully within the maneage subsystem.

I have one package that works fine with the openmpi options that are currently
used in Maneage, but another package fails semi-consistently on the same host,
within the same overall Maneage system.

Some of the packages that seem to have been installed from the host system
(CentOS 2.6.32-754.18.2.el6.x86_64), as indicated by the error tracing
messages, appear to be:


Openmpi is a *huge* package. I do not intend to try to solve this any time
soon. (A workaround is to run this particular program in serial mode, which is
an acceptable compromise.)

One possibility, that I might try if there's enough time, would be to update
to a more recent upstream Maneage, which *might* solve this.

However, I think that a proper Maneage install of openmpi, and thorough
testing on task schedulers like _slurm_, should be considered a major task.
