Hi Jeremy, Many thanks for this, I'll pass it over to our HPC guys to work on it (my grasp of this is a bit flimsy). On a related note. When tophat is running on one of our nodes it seems to be very slow and when we check the activity on the node we typically see that is is using about 6.8GB of ram and about 16.5 GB of virtual memory with about 1% CPU activity - presumably because there is a lot of I/O which slows down the run. Is this roughly what you would expect on an 8GB node? Each node is 8GB RAM and 1GB RAM per core. Anything we can do at this end to optimise this a bit?
Best Wishes, David. __________________________________ Dr David A.
