thanks! MPI_File_iwrite_all working as expected.

I'm always glad to see folks looking at the MPI-IO routines. Let us know how your research progresses. ==rob

I believe it is valid to do that in split collectives. If you want truly nonblocking nature, the standard way to do it would be to use nonblocking collective I/O, i.e., MPI_File_iwrite_all. This is guaranteed to not block during the MPI_File_iwrite_all call.
