WLM absoute real memory limit (50944 MB) exceeded

[christof_petrick@gfz-potsdam_de]

Hello,
I downloaded, configured and compiled CESM on our system (Blizzard, DKRZ) and I can start for example the following experiment: -res f45_g37 -compset B1850W.

However, if I intent to run for example f19_g16 I get the following error:
“WLM absoute real memory limit (50944 MB) exceeded” that means that f19_g16 eats up more than 50GB of RAM.

I assume I missed a setting somewhere along the line, so does anyone have an idea what causes this error and/or how to solve it?

Thanks you very much

I believe the error message is correct. Here are the memory stats from a successful B1850W compset run at f19_g16 using the following pe layout:


























(seq_mct_drv): =============== pes min memory highwater (MB) 822.988 ===============
(seq_mct_drv): =============== pes max memory highwater (MB) 1473.956 ===============

Making a rough estimate that the average memory highwater per task is about 1-GB, the total memory requirement for the run is about 96-GB.
