In the latest versions of libtool, the runtime library path is encoded with
a statement like:
LD_RUN_PATH="/scr_multipole/cary/facetsall/physics/uedge/par/uecxxpy/.libs:/contrib/babel-1.4.0-r6662p1-shared/lib:/scr_multipole/cary/facetsall/physics/uedge/par/uecxxpy:/scr_multipole/cary/volatile/ued
The only thing that changes is the required connectivity. It sounds to me
like you may have a firewall issue here, where cloud3 is blocking
connectivity from cloud6, but cloud6 is allowing connectivity from cloud3.
Is there a firewall in operation, per chance?

Task-farm or manager/worker recovery models typically depend on
intercommunicators (i.e., from MPI_Comm_spawn) and a resilient MPI
implementation. William Gropp and Ewing Lusk have a paper entitled
"Fault Tolerance in MPI Programs" that outlines how an application

You are both correct. If you simply type "mpirun pvserver", then we will
execute pvserver on whatever machine is local.
However, if you type "mpirun -n 1 -H host1 pvserver", then we will start
pvserver on the specified host. Note that mpirun will still be executing on
your local machine - but pvse

Hi
I guess "task-farming" could give you a certain amount of the kind of
fault-tolerance you want.
(i.e. a master process distributes tasks to idle slave processors -
however, this will only work
if the slave processes don't need to communicate with each other)

I have three machines: mine (daviddoria) and two identical remote machines
(cloud3 and cloud6). I can password-less ssh between any pair. The machines
are all 32bit running Fedora 11. OpenMPI was installed identically on each.
The .bashrc is identical on each. /etc/hosts is identical on each.

Thank you Dominik for all your help!!
I've solved the problem: execute : printenv > ~/.ssh/environment
edit /etc/ssh/sshd_config and set PermitUserEnvironment to "yes" and
check that UseLogin is set to "no"
scp hostname ~/.ssh/environment user@hostname:~/.ssh/environment
edit sshd_config on the
Hi all,
Thanks Durga for your reply.
Jeff, once you wrote code for Mandelbrot set to demonstrate fault tolerance
in LAM-MPI. i. e. killing any slave process doesn't
affect others. Exact behaviour I am looking for in Open MPI. I attempted,
but no luck. Can you please tell how to write such program

Hi,
Dose OpenMPI has the processors binding like command "taskset"? For
example, I started 16 MPI processes then I want to bind them with
specific processor.
How to do that?
Thank you very much.
Best Regards,
Amy
