I have used the pnetcdf layer with WRF 188.8.131.52 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.
