[Wrf-users] Segmentation fault with WRF-NMM

[Kemp, Eric M.]

Dear WRFer's:

I am trying to run WRF-NMM with RSL_LITE/MPI on an Itaninum-2 cluster.  I have
compiled the model (both version 2.2 and 2.2.1) with ifort 9.1.036 and icc
9.1.042.  When I try running the model in real data mode, a segmentation
fault occurs when calling the NOAH soil model.

Here is the stack trace:

forrtl: severe (174): SIGSEGV, segmentation fault occurred

I do not experience this problem when using the older NMM soil model (option
99 in the namelist file).  Also, I have been successful in running NMM on an AMD Opteron
cluster using the Portland Group compilers.

Has anyone else experienced this problem?
