Re: [OMPI users] OpenMPI with Portals4 transport

Hi Brian, I'm tracking a two different problems here. The first is that mtl-portals4 is segfaulting in PtlPut(). The second is a btl-portals4 problem you described here: > Not specifying CM gets an earlier segfault (defaults to ob1) and looks to be a progress thread initialization problem. I h

HI Brian, As a sanity check, can you see if the ob1 pml works okay, i.e. mpirun -n 2 --mca pml ob1 --mca btl self,vader,openib ./osu_latency Howard 2018-02-07 11:03 GMT-07:00 brian larkins : > Hello, > > I’m doing some work with Portals4 and am trying to run some MPI programs > using the Por
