Problem running standalone CLM5.0 on hcru grid

[matteo_zampieri@ec_europa_eu]

hello,

I'm trying to run CLM5.0 on a 0.5 degrees grid for the period around 2000

the case is created with options --res hcru_hcru --compset I2000Clm50BgcCrop --run-unsupported

I succesfully generated the surfdata map data with the command ./mksurfdata.pl -res 360x720cru -years 2000

The initialization of the model starts fine but then it stops with the following output >>>

Opening file clm_test4.cism.initial_hist.0001-01-01-00000.nc for output;

I tried with a cold start, but I'm getting the same outcome

Is this related to some common issue? Could you please help me?

Thanks,

Cheers,

Matteo

How many processors are you using? This probably comes out of the box with too few.

hi Keith,

thanks for the answer! I was using 32 processors that in my case works for the f09 grid. I increased till 192 but the simulation stops at the same point... do you think I still have to increase more or there is something else?

Cheers,

Matteo

With release-cesm2.1.3, I was able to run for one year with 1836 processors (71 model years/wall-clock day).
I've attached my env_mach_pes.xml file.
I also created a surface dataset using mksurfdata.pl.
Otherwise, everything in my simulation is out of the box.
What version of cesm/clm are you using?
Your traceback indicates line 269 of LakeTemperatureMod.F90 has a problem. Is there a clue there?
