[mpich-discuss] MPICH v3.2 and SLRUM

[Andreas Gocht]

Hey

I tried to build an use mpich with slurm, sbatch and srun. Unfortunate 
it looks like MPI_Init doesn't work with srun.

I got the following error:

Fatal error in MPI_Init: Other MPI error, error stack:
MPIR_Init_thread(474).................:
MPID_Init(190)........................: channel initialization failed
MPIDI_CH3_Init(89)....................:
MPID_nem_init(272)....................:
MPIDI_CH3I_Seg_commit(366)............:
MPIU_SHMW_Hnd_deserialize(324)........:
MPIU_SHMW_Seg_open(865)...............:
MPIU_SHMW_Seg_create_attach_templ(637): open failed - No such file or 
directory
In: PMI_Abort(4239887, Fatal error in MPI_Init: Other MPI error, error 
stack:

MPIU_SHMW_Seg_open(865)...............:
MPIU_SHMW_Seg_create_attach_templ(637): open failed - No such file or 
directory)

I configured MPICH with "./configure --prefix=<some/prefix> 
--with-pmi=slurm --with-pm=none --with-slurm=<path/to/slurm>" and 
compiled my application with the  "-L<path_to_slurm_lib> -lpmi" command.

(as described in

https://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Note_that_the_default_build_of_MPICH_will_work_fine_in_SLURM_environments._No_extra_steps_are_needed.

and

https://computing.llnl.gov/linux/slurm/mpi_guide.html#mpich2

)

I am running with 10 nodes and one task per node. Is there something I 
am missing during the configuration of MPICH?

Best,

Andreas
