Well, ROMIO was written by Argonne/MPICH (unfair to point the finger solely at

Ok, sorry about that!
thanks for the historical and technical informations!

I was afraid that was the case. Too bad, because applications (and the
files they use), are getting much too big for the 32 bit limit.

I think but I am not sure that it is because the MPI I/O (ROMIO) code is
the same f
I have experienced the same problem.. and worst, I have discovered a bug
in MPI I/O...

Hello:
A colleague and I are running an atmospheric ensemble data assimilation
system using MPIIO. We find that if for an individual
MPI_FILE_READ_AT_ALL the block of data read exceeds 2**31 elements, the
program fails. Our application is 32 bit fortran (Intel), so we
certainly can see why this
