I checked the forum and each GPU task requires 8 GB of system RAM! I had 2 tasks running (one for each turing GPU) and 16 GB of system RAM (3700X). I also had quantum chem tasks running on 14 threads so that explains why the system was using the swap file.I tried the new Amicable numbers GPU app on linux the other day and it used all the system RAM and started trashing the swap file. I wonder if the app has a memory leak. Has anyone else seen this?
