I have used the pnetcdf layer with WRF 3.0.1.1 but didn't have any 
problems.  The machines I used were a Cray XT4 and XT5, both with Lustre 
FS. I used the PGI compiler.

Have you tried the pnetcdf test cases (I can't remember how extensive 
they are though)?

Bit of a NULL result really but just wanted to reassure you that I've 
had it working.

Cheers,

Andy.
