Terry,
Your suggestion worked. So long as I specifically state "--without-tm",
the OpenMPI 1.2.4 build allows the use of "-hostfile". Apparently, by
default, OpenMPI 1.2.4 will incorporate Torque if it exists, so it is
necessary to specifically request "no Torque support". I used the normal
Torque processes to submit the job and specified "-hostfile $PBS_NODEFILE".
Everything worked.
Thanks for your help,

Can one not build OpenMPI without tm support and spawn remote jobs using
the other mechanisms, using only $PBS_NODEFILE (or a derivative of the
file that that points to) in the script?
