Re: [OMPI users] Incorrect file size from MPI_File_write (_all) when using MPI derived types for both view filetype and write datatype

ok, I found the problem, a book-keeping error when the read/write operations spans multiple internal cycles. Will commit a fix shortly to master, and will try to get a pr into the 3.0.x and the upcoming 3.1.x series, not sure however which precise release the fix will make it in. Thanks for

Yes, that does now give the expected behaviour from both Fortran and C both for the test codes and for my real code. Chris > On 6 Nov 2017, at 14:40, Gilles Gouaillardet > wrote: > > Chris, > > Can you try to > > mpirun --mca io romio314 ... > > And see if

yes, the result is correct in that case, we must be overrunning a counter or something similar in the ompio code. Edgar On 11/6/2017 8:40 AM, Gilles Gouaillardet wrote: Chris, Can you try to mpirun --mca io romio314 ... And see if it helps ? Cheers, Gilles Christopher Brady

I'll have a look at  it. I can confirm that I can replicate the problem, and I do not see an obvious mistake in your code for 1 process scenarios. Will keep you posted. Thanks Edgar On 11/6/2017 7:52 AM, Christopher Brady wrote: I have been working with a Fortran code that has to write a
