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 might be expected. Is this the case? We have a workaround by doing multiple reads from the file while moving the file view, so it isn't a serious problem.
Thanks for any advice or suggestions T. Rosmond
