Running julia code on multiple machines

Question

I have parallelized my algorithm using pmap. The performance improvement on one machine using the -p option is great. Now I would like to run on multiple machines.

I used the --machinefile option on julia start. It works but it launches only one process on remote machine. I would like to have multiple processes running on each machine. Option -p enables multiple processes only on the local machine. Is there a way to specify number of processes on remote machines?

On Julia 0.3 you have to list the remote machines multiple times to open multiple Julia copies.

On Julia 0.4 (unreleased) you can actually put a count next to each address, see this pull request.
