Problem with pbs node configuration

[Giorgio Padoan]

Hello people,


I am testing mpiexec 0.83 on my little cluster (10 nodes with Intel Quad-Core plus an front-end Intel Dual-Core).

On it I installed:

Torque-2.4.0-snap.200804241119
Maui-3.2.6p20-snap.1182974819
Mpich2-1.0.7

and, now, they work fine.



I have compiled mpiexec with:

./configure --prefix=/opt/mpich/mpiexec-0.83  --with-pbs=/opt/torque/2.4.0/ --disable-mpich-gm  --with-default-comm=mpich2 \
--disable-mpich-ib --disable-mpich-rai  --disable-lam  --disable-shmem --disable-emp  --disable-portals   \
--with-mpicc=/opt/mpich/2-1.0.7/bin/mpicc --with-mpif77=/opt/mpich/2-1.0.7/bin/mpif77  --with-sed=/bin/sed


If I try for mpiexec (Mpiexec-0.83) I get the following.


When I run the job:

#PBS -l nodes=2:ppn=2
qsub -q batch   ./go_mpiexec

where script "go_mpiexec" is:

/opt/mpich/mpiexec-0.83/bin/mpiexec -verbose --comm=mpich2  /home/giorgio/job/test/wave_mpi/Bstagj2mpi


Ouput file of Mpich2 logs:

node  0: name <my-name>, cpu avail 1
  ATT: must use at least 2 CPUs


I think that "mpiexec" do not see my /var/torque/server_priv/nodes file.

All the environments variable are correct in appearance.


Thanks for suggestions.
