I wrote a cluster manager for launching jobs on HTCondor<http://github.com/dbindel/ClusterManagers.jl>a little while back, and was having good luck with it, but now I seem to be having some trouble. The basic logic is that Julia starts a TCP server and launches jobs on the cluster that then connect to the server and send back their information (by piping through telnet). The problem is that somewhere between when the connection is accepted and when Julia tries to read the port information, "the connection is closed by the foreign host".
I've rebuilt Julia between when I last tested this and now, so it's possible that there was some change in Julia; it's also possible that there was a change in the cluster configuration, since that's equally a moving target. But I'm a bit foxed, and any insights would be welcome. Cheers, David
