I was able to get mpiexec to work with shared memory on my cluster. Here are the steps I took I had to rebuild mpich and mpiexec with shared memory
First I downloaded the OSCAR version of mpich-1.2.5.10 ( I picked this one so it would not overwrite anything I had before) I then installed the srpm I then copied the tarball to a temp directory visible to the whole cluster I untared it I then typed ./configure -cc=icc -fc=ifc -c++=icc --with-device=ch_p4 --with-comm=shared -rsh=ssh Next I typed make Then I typed make install --prefix=/opt/mpich-1.2.5.10 Then cexec make install --prefix=/opt/mpich-1.2.5.10 Then for mpiexec I downloaded mpiexec-0.75 and untared it I then typed ./configure --with-pbs=/opt/pbs --with-default-comm=mpich-p4 --disable-mpich-gm --disable-emp --with-comm=shared make make install This installed in the /usr/local/bin directory which is mounted across my system Now I'm not sure how to interface OSCARS switcher utility to add this new mpich so I just modify my path. This is a sample script to run my code To compile the code I used PATH=/opt/mpich-1.2.5.10/bin:$PATH export PATH mpiCC .... Then to run it under pbs #PBS -N s3948pd1.5 #PBS -l nodes=2:ppn=2 #PBS -o output #PBS -e errors #PBS -S /bin/bash #PBS -V # echo "I Ran on:" cat $PBS_NODEFILE # P4_GLOBMEMSIZE=100000000 export P4_GLOBMEMSIZE cd $PBS_O_WORKDIR PATH=/opt/mpich-1.2.5.10/bin:$PATH export PATH /usr/local/bin/mpiexec -v -comm mpich-p4 ~/workspace/mpi/test sim.cfg shapes.cfg I hope this helps **************************************************** Christopher D.
