[Wrf-users] running with pnetcdf

[Aaron Sims]

Using a RHEL5 Linux cluster, Ive compiled wrf 3.0.1.1 dm option with 
netcdf and pnetcdf using mpich2 and pgi7.2. I had no errors during 
compile and all exe's were produced. I am trying to do some mpp runs. 
When running with io_forms* set to 11 (parallel netcdf) I have no 
problems running on 4 procs but only if i use a single (dual proc /dual 
core - 4 processing cores) machine. But when I try to send the jobs out 
to more than 1 machine it just seems to hang. No errors are produced and 
nothing is happening when I issue a "top". It never dies but doesnt 
actually run either. RSL files are initially created and an empty wrfout 
file is created. Also, everything works fine when using io_forms* = 2 
(regular netcdf). Any suggestions?

Here is the only output in the rsl files:
rsl.out.0000:
taskid: 0 hostname: vapor1
