Subject: Re: [OMPI users] 2 GB limitation of MPI_File_write_all

Hi Rayson,

Just seen this.

In the end we've worked around it, by creating successive views of the file that are all else than 2GB and then offsetting them to eventually read in everything. It's a bit of a pain to keep track of, but it works at the moment.

I was intending on following your hints and trying to fix the bug myself, but I've been short on time so haven't gotten around to it yet.
