David,
It sounds like you have created the PGCC switcher file, but not pushed it
to the compute nodes. You'll need to add the file you've created on the
head node to the compute nodes. Something like this should work. (I find
examples much better than lots of verbiage.)
Assuming the dir you created MPICH PGCC is '/opt/mpich-pgcc' and that the
assiocated Switcher file (mpich-ch_p4-pgcc-1.2.4.10) is in
'/opt/mpich-pgcc/share/etc/'.
# Create an archive of the compile src including added Switcher file
# and distribute around the cluster.
root# tar -cf /opt/mpich-pgcc.tar /opt/mpich-pgcc
root# cpush /opt/mpich-pgcc.tar /tmp
root# cexec tar -xf /tmp/mpich-pgcc.tar -C /opt
root# crm /tmp/mpich-pgcc.tar
# Then add the the new MPICH PGCC name to the MPI tag on the cluster
# e.g., this will show up as 'mpich-pgcc' to user
root# switcher mpi --add-name mpich-pgcc /opt/mpich-pgcc
root# cexec switcher mpi --add-name mpich-pgcc /opt/mpich-pgcc
# Test things out as a standard user
root# su - bobby
bobby$ switcher mpi --show
system:default=mpich-ch_p4-gcc-1.2.5.10
system:exists=true
node0: $ switcher mpi = mpich-pgcc_test
Attribute successfully set; new attribute setting will be effective for
future shells
# And to return the user account to the system default
bobby$ switcher mpi --rm-attr default
Hope that helps,
--tjn
