Re: [OMPI users] Performance question about OpenMPI and MVAPICH2 on IB

I did rebuild OFED and put it in a different directory and did not rebuild OpenMPI. However, since ompi_info isn't complaining and the libraries are available, I am thinking that is isn't a problem. I could be wrong. Thanks, Craig -- Gerry Creager -- gerry.crea...@tamu.edu Texas Mesonet -

Re: [OMPI users] Any scientific application heavilyusing MPI_Barrier?

there are several explicit conditions that simplify (mostly) our calculations compared to _weather_ simulations. Use of a natural barrier would be better but that means it's harder for us to get 100 years of simulation time (or more) accomplished when we have to add natural barriers and r
