[slurm-users] PMIx and Slurm

[Paul Edmon]

So in an effort to future proof ourselves we are trying to build Slurm 
against PMIx, but when I tried to do so I got the following:

Transaction check error:
   file /usr/lib64/libpmi.so from install of 
slurm-17.02.9-1fasrc02.el7.centos.x86_64 conflicts with file from 
package pmix-2.0.2-1.el7.centos.x86_64
   file /usr/lib64/libpmi2.so from install of 
slurm-17.02.9-1fasrc02.el7.centos.x86_64 conflicts with file from 
package pmix-2.0.2-1.el7.centos.x86_64

This is with compiling Slurm with the --with-pmix=/usr option.  A few 
things:

1. I'm surprised when I tell it to use PMIx it still builds its own 
versions of libpmi and pmi2 given that PMIx handles that now.

2. Does this mean I have to install PMIx in a nondefault location?  If 
so how does that work with user build codes?  I'd rather not have 
multiple versions of PMI around for people to build against.

3.  What is the right way of building PMIx and Slurm such that they 
interoperate properly?

Suffice it to say little to no documentation exists on how to properly 
this, so any guidance would be much appreciated.
