thanks! MPI_File_iwrite_all working as expected. -Pramod On Tue, Feb 9, 2016 at 12:52 AM, Balaji, Pavan <[email protected]> wrote:

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.

Hello All,

I am testing MPI_FIle_write_all_begin/_end and it seems like MPI_File_write_all_begin waits for i/o completion.

Could someone confirm the implementation of these routines?

Thanks, Pramod _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
