I'm not completely certain, but I think it can run for a bit some
times. Bogart can use quite a long time, a couple of weeks depending
on your amount of data and genome. It seems that you are using CA 7.0,
if you use the CVS version you can take advantage of all those 64 CPUs
you have, and complete the bogart stage much, much quicker than if you
use only one CPU (which is the case for CA 7.0).
