Too much load on node where > mpirun is run? No, the error means the connection was completely lost - i.e., the socket was closed. Do I understand correctly that the job runs for awhile and then dies? So there are processes executing on the node that reports a lost connection? Or is this happening on startup of the larger job, or during a call to MPI_Comm_spawn? > > -- > > Jure Pečar > http://jure.pecar.org > > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users
