Increase Java heap size in cluster start script #11

Closed NicMcPhee closed 9 years ago

NicMcPhee commented 9 years ago

I did a few Lid runs as an experiment and about 2/3 of the runs ran out of memory. This is likely to be a issue on some of the other problems as well, so I should add the "increase heap size" parameter to the fly_launcher.py script that sets up the runs on the cluster.

I added -Xms1g -Xmx4g to the Java command. This starts the heap size at 1Gb with a max heap size of 4G. I'm hoping this will be sufficient, and it should be well within the capacity of the boxes on the Hampshire cluster. There are a bunch of boxes on the cluster with over 20Gb of RAM so we can go quite a bit higher if necessary, but let's try this for now.
