Dear Team
I downloaded and built WRF Model Version 4.2.1 and tried to run it on aws RHEL (x86_64) system.
When I run wrf.exe on 96vCPUs instance with 8 processes * 12 threads, I get segmentation fault.
However, when I run it in 6 processes * 16 threads, it ends normally.
I would like to use a cluster to do large scale calculations and get results faster.
What is the cause of a segmentation fault?
I set "ulimit -s unlimited" before execution.
compiler -> intel 19.1.2.254 20200623
MPI -> Intel(R) MPI Library 2019 Update 8 for Linux*
Attach namelist.input, rsl.output. * And rsl.error. *.
