<P> </P>
<P>for IOR HPC Benchmark, there is a filesize limitation of 2 GB for PnetCDF as follow. Do you know the reason, or just a bug? How can I test large file IO in IOR with NCMPI (Certainly I can update the code to 1024)? do I need to set some special environment varibles for it?</P>
<P> </P>
<P>Thanks,</P>
