Re: [OMPI users] Can't connect using MPI Ports

I did a quick check across the v2.1 and v3.0 OMPI releases and both failed, though with different signatures. Looks like a problem in the OMPI dynamics integration (i.e., the PMIx library looked like it was doing the right things). I’d suggest filing an issue on the OMPI github site so someone c

Hello, I'm working on a sample program to connect two MPI communicators launched with mpirun using Ports. Firstly, I use MPI_Open_port to obtain a name and write that to a file: if (options.participant == A) { // A publishes the port if (options.commType == single and rank == 0) ope
