Hello, I am running open-mpi between a Mac OSX (v.10.5) and Ubuntu Server V.9.04 (Linux Box). I have configured OMPI V.1.3.3 on both of them with --enable-heterogeneous --disable-shared --enable-static options. The Linux box is connected via a wireless USB Adapter to the same sub-network in which the Macinstosh is sitting.
When I tried to run mpirun with the following options between the Linux box with the wireless card with another linux machine on the network everything works fine. I ran : /usr/local/bin/mpirun --mca OMPI_mca_mpi_preconnect_all 1 -np 2 -H localhost,10.11.14.205 ./app and it works. When I tried to run mpirun with the -hetero option from the Macintosh it invokes the processes on both ends and then hangs at the MPI_Send MPI_Receive functions. I ran: /usr/local/bin/mpirun --mca btl_base_verbose 30 --mca OMPI_mca_mpi_preconnect_all 1 -np 2 -hetero -H localhost,10.11.14.205 ./app and it hangs. I saw that the linux box is trying to connect() the Mac using port 4/260. So I purposely forced mpi to look for higher numbered ports.. I ran : /usr/local/bin/mpirun --mca btl_tcp_port_min_v4 36900 -mca btl_tcp_port_range_v4 32 --mca btl_base_verbose 30 --mca OMPI_mca_mpi_preconnect_all 1 -np 2 -hetero -H localhost,10.11.14.205 ./app and it still hangs giving the following message: btl: tcp: attempting to connect() to address 10.11.14.203 on port 9360 10.11.14.203 == localhost. Can anybody explain what I am missing and how I can make the macintosh and Linux boxes talk to each other over wireless.. regards, pallab
