[RegCNET] Segmentation fault : terrain genaration with subgrid

[Dhirendra Kumar]

Dear RegCNET users,

greetings for the day.....

I am planning to use subgrid option with RegCM-4.4.5.5 on my cluster having
following specifications-

​processor       : 0     #similar configuration for 0-8 processor
vendor_id       : GenuineIntel
cpu family      : 6
model           : 45

stepping        : 7
cpu MHz         : 1400.000
cache size      : 10240 KB

power management:

I am running the terrain program using-
./bin/terrain test_014.in
and it ends without completion with segmentation fault.
​
then I tried *mpirun -np 72 ./bin/terrain test_014.in <http://test_014.in/>*,
which takes too long and terminates with the error-

*netcdf: Memory allocation (malloc) failure mod_rdldtr.F90 : 171:NetCDF
Error: -61 abort: Fortran Abort Called*

followed by the segmentation fault. Also I am not able to run with the
ROTMER projection option with 2 subgrid on.
I am not sure if it is related to available memory for performing the
computation. Please help me understand and solve this.
I am attaching the namelist file for the reference.

Any help would be appreciated.

Thanks in anticipation.
