#2203 closed Defect (fixed)

Compilation compliant with MPI-2 standard

Reported by: rblod Owned by: smasson
Priority: low Milestone: Unscheduled
Component: LBC Version: trunk
Severity: minor Keywords: MPI, lib_mpp,
Cc:

Description

Context

Compilation with key_mpp_mpi fails with some versions of mpi libraries

Analysis

mpi_iallreduce appeared with MPI-3.0 standard

Recommendation

It's not a bug, more a matter of choice. I may advice to add a logical to be able to switch back to MPI-2 compatibility, since MPI-3 is not so old. Or specify requirements somewhere. Or just mark this ticket as invalid.

This point has been discussed during our last VC: wiki:SystemTeam/Agenda/2018-12-20

I share your view that MPI 3.0 series is probably a little too recent for some people: https://www.open-mpi.org/software/ompi/versions/timeline.php

I think this commit is pretty useless but it was not too difficult to do… :-)
