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:
/lib64/libc.so.6
/lib64/libpthread.so.0
/usr/lib64/ld-2.17.so
/usr/lib64/libdl-2.17.so
/usr/lib64/libm-2.17.so
/usr/lib64/libutil-2.17.so
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.
