Hi,
I had setup Open MPI "trunk_16171" for 3 computers with Lan connection, and
set environment parameters, ssh without typing password for each node. I use
Red Hat Enterprise Linux 5. The program I tried is 'send_recv'. I run
successful my 'send_recv' program in those 3 nodes. And checkpoint/resta

This is not true (as far as I know...). Open MPI has 2 di

Hi Joao,
Unfortunately Comm_spawn is a bit broken right now on the Open MPI trunk. We
are currently working on some major changes to the runtime system, so I would
rather not dig into this until these changes have made it onto the trunk.
I do not know of a timeline for when this these changes w

I switched on -mca oob_tcp_debug 1000 and the result is below.
Later on there's an "ifconfig -a" as the trace seems to show you are trying

Hello,
In the context of my PhD research, I have been developing a run-time
performance analyzer for MPI-based applications.
My tool provides a controller process for each MPI task. In particular, when
a MPI job is started, a special wrapper script is generated that first
starts my controller proc

Hi all!
I'm getting a error on call MPI_Init_thread and MPI_Comm_spawn.
am I mistaking something?

Now that the PATHs seem to be set correctly for

Is the error message still the same on as in the first mail?
Did you do the envorpnment/sshd_config on both machines?
What shell are you using?
On other test you could make is to start your application

Hi Jodi,
did the steps as you said, but it didn't work for me.
I set LD_LIBRARY_PATH in /etc/environment and ~/.shh/environment and
made the changes to sshd_config.
But this all didn't solve my problem, although the pahts seemed to be
set correctly (judging what ssh saturn `printenv >> test` says)

So you know this is something that we are working on for the next major
release of Open MPI (v 1.3). More details on some of the discussion can
be found here:

hello,
I am using Open MPI 1.2.3 to run a task on 4 hosts as follows:
amit@ubuntu-desktop-1:~/mpi-exec$ mpirun --np 4 --hostfile
mpi-host-file ParallelSearch
bash: /usr/local/bin/orted: No such file or directory
The problem is that 'orted' is not found on one of the 4 hosts. I
investigated the p
Specifying nodes several times in the hostfile or with the --host
parameter seems to just add up the number of slots availible for the
given node. It doesn't seem to affect the mapping of the ranks. I think
this is due to how the hostfile is read into the structure that holds this
information
How about a hostfile such as
% cat -n ~/tmp/hostfile
1 node0
2 node0
3 node1
4 node0
5 node1
6 node1
Looks like the function to express the mapping is not anything simple. If it's
an expressible function but too complicated for open mpi, you'll have to make

Oh man, sorry about that, and thanks for the fast response.
Let me try again, please :)
I want to manually specify what ranks should run on what node.
Here is an example of a mapping that I can't seem to be able to do, since
it isn't a round-robin type of mapping.

Hello,
I compile openmpi 1.2.3 with options ./configure --with-threads=posix
--enable-mpi-thread --enable-progress-threads --enable-smp-locks.
My program has 2 threads (main thread and an other). When i run it, i
can see 4 threads. I think that two threads are the progress threads, is
it right ?

I guess there must be a typo:
You can't assign one rank (4) to two nodes
And ranks start from 0 not from 1.
Check this site,

there might be some inforegarding your problem.

One more thing to add -mca mtl mx uses ethernet and IP emulation of
Myrinet to my knowledge. I want to use Myrinet(not its IP Emulation)
and shared memory simultaneously.
Thanks
