Ah, wait -- based on your mail, I checked the MPI_Info-checking code in our
underlying spawn implementation and basically found an uninitialized variable.
Hence, it's probably non-deterministic behavior.
Patch coming to the development trunk soon; I'll get it QA checked by someone
more expert i
Thanks for that info!
I was literally just digging into this myself; I am able to replicate the
problem on a 1.5.1 tarball, but not on a nightly 1.5.2 snapshot tarball. Would

useful for someone else. The problem stems from ompi_local_slave option
being set on its own in the MPI_Info structure. It seems that
MPI_Info_create is using a shift or more likely a masking operation
(depending upon th
Try using MPI_COMM_REMOTE_SIZE to get the size of the remote group in an
intercommunicator. MPI_COMM_SIZE returns the size of the local group.
