Hi !
finally I got it:
passing the mca key/value `"plm_slurm_args"/"--chdir /local/folder"' does the
trick.
As a matter of fact, my code pass the MPI_Info key/value
`"wdir"/"/local/folder"'
to MPI_Comm_spawn as well: the working directories on the nodes of the spawned
programs
are `nodes:/local/folder' as expected, but the working directory of the oreted_s
is the working directory of the parent program. My guess is that the MPI_Info
key/vale
may also be passed to `srun'.

Hello List,
I have just noticed that, when MPI_Comm_spawn is used to launch
programs around,
oreted working directory on the nodes is the working directory of the
spawnning program:
can we ask to oreted to use an another directory ?
Changing the working the directory via chdir before spawning with
MPI_Comm_spawn
changes nothing: the oreted working directory on the nodes seems to be
imposed
by something else. As run OMPI on top of SLURM, I guess this is related
to SLURM.

Thanks in advance,
