Greetings RegCMers,
I am trying to run RegCM with the 12 bin dust option (DU12). But
when I set my domain over the Sahara region I get the following
error. When my domain is set in northern latitudes RegCM seems to
run fine. Also when I lower the number of the total grid points or
when I am using the 4 dust bin option the simulation is completed
without any problem. I am including the *.in file and the output of
the model+error.
Since the error is occurs in regcmMPI, there must be a problem with
parallel processing. I am running my experiments on 24 cores. I
already tried the "ulimit -s unlimited" before running mpirun.
Any hint or suggestions is greatly appreciated,
Best wishes,
Thanos
ps: You have to disable the chem BC to test the experiment in the
*.in file I am including.
