Re: [OMPI users] difference of behaviour for MPI_Publish_name between openmpi-1.4.5 and openmpi-1.8.4

Thanks Gilles! That works with this MPI_Info given to MPI_Publish_name. Cheers, Bernard Le 08/01/2015 03:47, Gilles Gouaillardet a écrit : Well, per the source code, this is not a bug but a feature : from publish function from ompi/mca/pubsub/orte/pubsub_orte.c
