Re: cluster with 30 nodes, 2 slots each, 50 job max?

The issue appears to be that the nodes were added with `starcluster loadbalance` and for some reason SGE was not configured properly for one round of 5 nodes that were added. They show up as being part of the cluster in starcluster, but SGE does not recognize them. Wonder what went wrong…

For some reason though after 50 jobs are running, the system just queues jobs. I have tried kicking off simple sleep jobs to see if those can run over the 50 wall I am hitting, but no luck (qsub -V -b y -cwd sleep 10). I do not see anything odd about my settings. Is this something hard-coded somewhere that I can change? Has anyone been able to run more than 50 jobs at a time with starcluster?
