Hi all, I need to read a file, using MPI_set_view. The problem occurs when the file is so large that the offset that I need to provide to the MPI_set_view is larger than the maximum value for an integer. For example I need to set the offset to 3826145886. In some documentation I've read the offset is a long, but in other it indicates its an integer. Is there any possible work around this? Could the offset be set to negative, and if so, will it start at the end of the file? I have installed mpich2-1.3.1. Thank you,
