[mpich-discuss] MPI I/O spilt collective implementation: MPI_File_write_all_begin blocking or non-blocking?

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
