[Wrf-users] WRF3.1.1 and WRF3.2; PGI compiler with gcc (smpar)

Dear wrf-users,


I am running WRF3.1.1 on a linux x86_64 bit with PGI 8.0-4, gcc4.3.4, and
netcdf 3.6.3. I successfully compiled wrf with smpar, but when I run
./wrf.exe on multiple processers, wrf exits with segmentation fault after
about 9 to 20 time steps. 


I read that my OMP_STACKSIZE may be too large, but this problem still occurs
when I set the stack size as low as 2GB. I have also downloaded WRF3.2, but
wrf.exe still does not run under smpar with PGI compilers. 


Note, wrf.exe runs fine on 1 processor and with the gfortran compilers. 


Any input on how to run WRF under the smpar setting with PGI compilers is
much appreciated.


Thank you,
