Description James Sharpe 2017-10-17 04:38:59 MDT 
This is really following on from an old mailing list post here: https://groups.google.com/d/topic/slurm-devel/eCrFsV60zQo/discussion
where a workaround for this issue was used but it doesn't resolve the underlying problem.

I've observed this on a slurm install at version 15.08 (this is a third party site that I have no control over). I don't currently have a newer slurm install to hand to check whether this is still an issue on current versions but will check when I have time.



Basically the issue is that the slurm plugins have unresolved symbols and so forcing them to be resolved at load time by setting LD_BIND_NOW=1 in the environment causes slurm jobs to fail (and hang until they timeout due to time limits, although this may also be due to a deadlock in the PMI implementation of Intel MPI)
