[Wrf-users] weird problem on runing real.exe

Hi all. I run WRF3.3 on IBM AIX platform. I came up with some weird problems when executing real.exe. If 96 cpus on 3 nodes (32 cpus per node) was used, the program would stop at the second  boundary time with segmentation fault. However, If 8 cpus on 1 nodes was used, the program run successfully. I  also used WRF3.5 to make a test and found that the program real.exe finished successfully when 96 cpus on 3 nodes is used. I can't figure out why the situation happened
If anybody know the reason, please tell me. Thank you.
