@ahaponski_twitter Hi Amanda. Is this correct that your university HPC limits RAM to 3800mb (i.e. ~4Gb)? This is probably what's causing the holdup, we recommend 4GB per core, and you've got 4GB for 16 cores. If you can't get more ram you could try reducing the number of cores, this could speed it up (if it's running out of RAM, then reducing the number of cores will reduce ram usage and reduce paging, which would make it go faster).
