Apart from some small daemons there is nothing else running. The
application does no I/O except at the start and finish. All during the
run TOP shows a working set size of "8GB" and "13.9GB" for "memory
allocated". From my knowledge of the program I would have expected the
working set to be about 13.8GB. This led me to suspect there was a
switch somewhere that regulated the maximum working set size.
