<P><FONT SIZE=2>Dear WRFer's:<BR>
<BR>
I am trying to run WRF-NMM with RSL_LITE/MPI on an Itaninum-2 cluster. I have<BR>
compiled the model (both version 2.2 and 2.2.1) with ifort 9.1.036 and icc<BR>
9.1.042. When I try running the model in real data mode, a segmentation<BR>
fault occurs when calling the NOAH soil model.<BR>
<BR>
Here is the stack trace:<BR>
<BR>
forrtl: severe (174): SIGSEGV, segmentation fault occurred<BR>

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