Hi All,
I continue my testing of NetCDF-4 parallel I/O in ROMS.
It works fine in several different applications but it is
failing in one with larger grid size. My interface is generic
so all the applications are using the same sequence of calls
but with different grid size.
I am using:
4.0.1-beta2-snapshot2009011202 of Jan 14 2009 10:13:17 $
mpich2-1.0.8 and pgf90 8.0
Linux 2.6.9-42.ELsmp #1 SMP Tue Aug 15 10:35:26 BST 2006 x86_64 x86_64 x86_64
GNU/Linux
Here is the error that I get when writing the first
variable into the created NetCDF-4 file:
DEF_HIS - creating history file: latte_his.nc

Since the error is internal it is difficult to follow in the
debugger. I haven't been able to reproduce the error in a
much simpler program.
I was wonder if anybody has seen this problem before. This seems
to be a HDF5 error, perhaps it needs to be send to that group.
Thank you, H
