I can't recall anything that has changed in the parallel codebase recently. You could try with the 0.2 version just to be sure. Maybe the the julia processes on the cluster are dying soon after they launch, and hence the closed connection while reading port information? Could you try launching julia manually on any of the nodes of the cluster, just to ensure that the julia setup on those nodes are OK?
