I can not reproduce the problem. It seems that there is a buffer
overflow in PMI2 client of MPICH.

to follow up:
after fixing an issue in the source of mpich2 simple2pmi.c ( which
overruns a snprintf buffer ), the spawn interface started to work.
however other things started to break ( eg the singleton mode, when no
srun was provided ).
Pavan Balaji directed me to these steps, which works

Hi Yiannis,
thanks for your reply, but unfortunately i still seem to having issues.
i've rebuilt mpich2-3.0.2
./configure --with-slurm=/local1/slurm-2.5.4_INSTALL/ --with-pmi=pmi2
--enable-pmiport --prefix=/local1/mpich-3.0.2_SLURM/ --enable-shared
--enable-cxx ;
now I'm crashing right away i
Hi Christoph,
you need to make use of PMI2 version of slurm to test MPI_comm_spawn
primitive of mpich2.
In more detail, you have to rebuilt your mpich2 adding the following
flags on your configure:
--enable-pmiport --with-pmi=pmi2--with-slurm=$YOUR_SLURM
and when you run jobs with slurm y
