Hi,
Yes the fix for exactly that was submitted by me at end of 2014th:
https://github.com/SchedMD/slurm/commit/7fff5eed6b8fe97347a832149966ed11f5805f99
You need to track if it was included to your version.

Hi Artem,
Do you know if a fix for this was ever committed? We ran into this with a
code base that builds non-mpi apps with mpicc and then attempts to run then
multiple times from within a single SLURM task.

You debugging and analysis is correct.
PMI2_init() initialize PMI in two steps. First a PMI 1.1 init command is
sent to the server and the version is negotiated with the server. After
that a PMI 2.0 fullinit command is sent. Everything goes well so far.
But since the version number is decided, th

That is correct. We think of this exactly that way.

I'd like to mention that the mpi/pmi2 plugin of SLURM also supports
PMI1.1. If no --mpi=pmi2 option given, the PMI implementation in SLURM
will be used, which supports PMI1.1 only.

I will check the double init hang problem.

Thank you, Chris!
Currently we have a prototype that selects PMI version based on:
(a) user preference, in this case if PMI2 return error - we give up and
MPI_Init fails.
(b) automatic: here if we see the that PMI2 wasn't enabled (no --mpi=pmi2
option) we rollback to PMI1. This case also includes

It's also worth noting that because of problem reports about PMI2 with
Slurm to the OMPI developers t
Here is an exact examples:
1. "appnum = -1" problem:
Program pmi_appnum.c (attached) is allocated using batch script
pmi_appnum.job (attached) and produces following results:
PMI2_Init(0, 16, 0, -1)
PMI2_Init(0, 16, 1, -1)
PMI2_Init(0, 16, 2, -1)
PMI2_Init(0, 16, 3, -1)
PMI2_Init(0, 16, 5, -1)

Thank you.
I need to add that I am working on
The srun --mpi=pmi2 option has to be specified if openmpi was built with
the --with-pmi options otherwise Slurm will not load the pmi2 plugins
and the mpi job will fail in MPI_Init().
