Replace MPI_LB/UB usage with MPI_Type_create_resized #6

Closed hjelmn closed 6 years ago

hjelmn commented 6 years ago

The MPI_LB and MPI_UB markers were removed from the MPI standard in MPI-3.0. Their use was deprecated in MPI-2.

This goes one step further than #5 and removes the MPI_LB/UB usage.

@VinnitskiV, @itemko Is there a schedule for when this might get into IMB? Open MPI v4.0.0 is scheduled to release September 17th, and it would be nice if it could compile and run IMB without enabling the old MPI 1 removed APIs.

I verified this branch builds and runs okay with Open MPI v4.0.0rc1 with default configure options (i.e. without --enable-mpi1-compatibility)
