Implicit error when changing the PE_LAYOUT

[xyli@geo_uio_no]

Dear Madam/Sir,

After I changed the PE_LAYOUT, the job was terminated due to unknown reasons.
Any idea about this?
Attached please kindly find the error message reprot.

Here is the procedure I followed
./create_newcase --case ~/cases/FW1850_PE --compset FW1850 --res f09_f09_mg17 --machine tetralith

./xmlchange NTASKS_ATM=128
./xmlchange NTASKS_CPL=2
./xmlchange NTASKS_LND=1
./xmlchange NTASKS_ICE=1
./xmlchange NTASKS_OCN=1
./xmlchange NTASKS_ROF=1
./xmlchange NTASKS_GLC=1
./xmlchange NTASKS_WAV=1

./case.setup

./case.build

./case.submit

Best regards,

Xiang-Yu Li

The FW case at f09_f09_mg17 is a rather large model, along with the atm component it includes a land model and a coupler.  You are specifying way too few processes for those components.   I would suggest changing all components to have 120 tasks:./xmlchange NTASKS=128and trying again.   That should work but is still very small, if you have access to more processors you may want to use them, try 1024 for example.

Thanks a lot, Jedwards.
I will eventually push to 1024 CPUs for the production run.
For now, I am playing around with the optimum PE-LAYOUT.
I checked the Run Time for each component (CPL, ATM, LAND, ...)
and found that the ATM module takes up most of the CPU time.
So I designed a PE-LAYOUT according to the following Run Time statistics.

It seems that assign 1024 CPUs for all the modules will waste a lot of CPU resources?

TOT Run Time: 27680.976 seconds 892.935 seconds/mday 0.27 myears/wday
