<div>Dear Jawad,</div><div>Without any output file, it is hard to guess what the issue is. Could you maybe run a short MD (a few frames) and provide the output file? I am especially interested in the statistics part at the end of the output file (Timing report, "MEMORY| Estimated peak process memory [MiB]"). Please provide the full input file you used (not necessarily the geometry files) because you commented out the cell definition in your input file.<br /></div><div>Best,</div><div>Frederick<br /></div><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">Jawad Elhamdaoui schrieb am Mittwoch, 27.
