The mac is a Two 2.26GHz Quad-Core Intel Xeon Mac Pro and the
Linux
Box is
Ubuntu Server Edition 9.04. The Mac has the ethernet interface to
connect
to the network and the linux box connects via a wireless adapter
(IOGEAR).
Please help me any way I can fix this issue. It really needs to
work
for
our project.
thanks in advance,
regards,
pallab
My other concern was the following but I am not sure it applies
here.
If you have multiple interfaces on the node, and they are on the
same
subnet, then you cannot actually select what IP address to go out
of.
You can only select the IP address you want to connect to. In
these
cases, I have seen a hang because we think we are selecting an IP
address to go out of, but it actually goes out the other one.
Perhaps you can send the User's list the output from "ifconfig"
on
each
of the machines which would show all the interfaces. You need to
get the
right arguments for ifconfig depending on the OS you are running
on.
One thought is make sure the ethernet interface is marked down on
both
boxes if that is possible.

Any suggestions on to how to debug this further..??
do you think I need to enable any other option besides
heterogeneous at
the configure proompt.?
The -enable-heterogeneous should do the trick. And to answer
the
previous question, yes, put both of the interfaces in the
include
list.
--mca btl_tcp_if_include en0,wlan0
If that does not work, then I may have one other thought why it
might
not work although perhaps not a solution.

Hi Rolf,
Do i need to configure openmpi with some specific options
apart
from
--enable-heterogeneous..?
I am currently using
./configure --prefix=/usr/local/ --enable-heterogeneous
--disable-static
--enable-shared --enable-debug
on both ends...is the above correct..?! Please let me know.
thanks and regards,
pallab
Hi:
I assume if you wait several minutes than your program will
actually
time out, yes? I guess I have two suggestions. First, can
you
run a
non-MPI job using the wireless? Something like hostname?
Secondly,
you
may want to specify the specific interfaces you want it to
use
on the
two machines. You can do that via the "--mca
btl_tcp_if_include"
run-time parameter. Just list the ones that you expect it to
use.
Also, this is not right - "--mca OMPI_mca_mpi_preconnect_all
1" It
should be --mca mpi_preconnect_mpi 1 if you want to do the
connection
during MPI_Init.

Hi
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
--enable-static
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,10.11.14.205
/tmp/back
it hangs on a send receive function between the two ends.
All
my
firewalls
are turned off at the macintosh end. PLEASE HELP ASAP>
regards,
pallab
