Sure - how about this:
Yes, if you have configured OMPI --with-pmi=foo, where foo is the path to
the directory where pmi.h/pmi2.h is located. Slurm (> 2.6, > 14.03)
installs PMI-2 support by default.
Older versions of Slurm install PMI-1 by default. If you desire PMI-2,
Slurm requires that you manually install that support. When the --with-pmi
option is given, OMPI will automatically determine if PMI-2 support was
built and use it in place of PMI-1.
4. Any issues with Slurm 2.6.3, 14.03?
Yes. The Slurm 2.6.3, 14.03 releases have a bug in their PMI-2 support.
For the slurm-2.6 branch, it is recommended to use the latest version
(2.6.9 as of 2014/4) which works with pmi2.
For the slurm-14.03 branch, the fix will be in 14.03.1.
