I noticed that I was spitting this out on stderr: Is this an OpenMPI problem?

Perhaps they are still waiting incorrectly to recived some message or something like that. Sometimes it seems to work. Is there a good way to get to the bottom of this error? ----output----- 4 additional processes aborted (not shown) Sam Adams General Dynamics Information Technology Phone: 210.536.5945 _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
