Subject: [OMPI users] Open-MPI between Mac and Linux (ubuntu 9.04) over wireless
From: Pallab Datta (datta_at_[hidden])
Date: 2009-09-21 18:50:12


I am trying to run open-mpi 1.3.3. between a linux box running ubuntu
server v.9.04 and a Macintosh. I have configured openmpi with the
following options.:
./configure --prefix=/usr/local/ --enable-heterogeneous --disable-shared

When both the machines are connected to the network via ethernet cables
openmpi works fine.

But when I switch the linux box to a wireless adapter i can reach (ping)
the macintosh
but openmpi hangs on a hello world program.

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,

it hangs on a send receive function between the two ends. All my firewalls
are turned off at the macintosh end. PLEASE HELP ASAP>
