As mentioned, I'm running in a chroot environment, so rsh and ssh won't work: "rsh localhost" will rsh into the primary local host environment, not the chroot, which will fail.
[The purpose is to be able to build and test MPI programs in the Debian unstable distribution, without upgrading the whole machine to unstable. Though most machines I use for this purpose run Debian stable or testing, the machine I'm currently using runs a very old Fedora, for which I don't think OpenMPI is available.] With MPICH, mpirun -np 1 just runs the new process in the current context, without rsh/ssh, so it works in a chroot. Does OpenMPI not support this functionality? Thanks, Adam On Wed, 2007-07-18 at 11:09 -0400, Tim Prins wrote: > This is strange.
