It doesn't matter how many WUs I run. Currently, 7 WUs are running on 4 cores. Memory consumption is a comfortable 29 GB out of 64 GB. The runtime is 1500–1700 seconds. Do you have the same problem or idea? ID: 52593 · Reply Quote

CMS is currently running "empty tasks" since the backend queue doesn't work as it should. Best would be not to run them as they are without any scientific value.
