I meant that the MPI package doesn't create standard Julia workers, and hence doesn't allow you to using things like `remotecall(...)` and other julia-specific parallel constructs. By using the MPI package you are restricted to using the constructs supplied in the MPI package (or so it appears to me).
I ended up playing with the JuliaManagers package, which deploys to a cluster, but the PBSManager there was lacking some features I needed and I ended up writing a new ClusterManager for Torque that supports deploying workers using qsub.
