Folks; I have been trying to get a test case up and running using a client server scenario with a server waiting on MPI_Comm_accept and the client trying to connect via MPI_Comm_connect. The port value is written to a file. The client opens the file and reads the port value. I ru

[OMPI users] Launching hybrid MPI/OpenMP jobs on a cluster: correct OpenMPI flags?

2016-10-03 Thread Wirawan Purwanto
Hi, I have been trying to understand how to correctly launch hybrid MPI/OpenMP (i.e. multi-threaded MPI jobs) with mpirun. I am quite puzzled as to what is the correct command-line options to use. The description on mpirun man page is very confusing and I could not get what I wanted. A background

Hello, Consider that OMPI-2.0.1 has been installed with --enable-mpirun-prefix-by-default. Now, is it possible to install OMPI-1.6.5 in its own folder and use it without any problem? I mean, if I run ompi-1.6.5/bin/mpirun, I want to be sure that ompi-2.0.1/lib is not in use. Please let me know, i
