Excellent. The bug fix will be in 1.6.1, too.

Dear all
I think I find the culprit.
I was calculating my offset using
offset = my_rank*dim
where dim is the array size. Both my_rank and dim are normal integers and
here lies the rub.
Fortran (or should I say gfortran?) multiplies my_rank*dim in integer*4
and then converts to integ

Ok, good.

Or the OMPI bug

Is it not a 64 bit integer for your compiler?
I'm still interested in the answer to this question.

Ouch! Looking at the thread you cited, it looks like George never followed up

Hi all

Hi all

I'm trying to use MPI-IO to write the file with all processes taking part

Using 64 processes the ofsett is my_rank * dim
and so...
what file system is this on?
gluster connected by infiniband. all disks in the same machine, everyone
speaks on infiniband.
