[mpi] Collectives on intercommunicator ?
Am I correct in assuming that collective communications are not supported with Boost.MPI intercommunicators ? Thanks -- Alain Miniussi Responsable Tech. Centre de Calcul Haute Performance Observatoire de la Côte d'Azur - BP 4229 - 06304 Nice Cedex 4 tel: +33 4 92 00 30 09 https://crimson.oca.eu
Hi Alain, At the moment Boost.MPI only supports MPI-1 and thus no intercommunicators. Do you want to help implementing them? Matthias On Oct 10, 2012, at 22:33, Alain O Miniussi <alain.miniussi@oca.eu> wrote:

Hi Matthias, Yes, I'm going to need them, so... I haven't look deeply into Boost.MPI yet, so it might be slow at first :-) Just to make sure I get at least the development process right, could you have a look into: https://svn.boost.org/trac/boost/ticket/6704 where I submitted a patch ?
