Hi every one
I want install openmpi in a cluster with multicore processor.
Is it necessary to configure with --enable-mpi-threads option?
when this option should be used?

Hi all,
I have written mandelbrot rendering using X11.I have two nodes with OpenMPI.
In my code, the rank 0 node(master) does the data collection from
salves, Window creation using X11 and render the graph.(using
XCreateSimpleWindow() ). Slave nodes calculate and send data to master.
But whe
Your cmd line specified that we are only to use the host "biggserver",
so all ranks will go there.
If you want ranks to go somewhere else, then you need to include that
location in your -host spec. See "man orte_hosts" for details.

Open MPI's threading support is functional but not optimized.
It depends on the problem y

Do anyone of you know any open source application level checkpointing tools
Dear Kritiraj,
You can use DMTCP http://sourceforge.net/projects/dmtcp

Dear All,
I can manually checkpoint an MPI application using OPEN MPI and BLCR.
However, I now want to checkpointing my application automatically at every 5
minutes. Is there a way in OPEN MPI to ensure automatic checkpointing without
the user intervention while the application is run
Dear Mohamed,
Thank you for the link

Dear Mohamed,
Is there some checkpointing software for interconnect other than
tcp say IB or Myrinet?

Sorry but the question is not very clear.

Hi,
I think that you can write a simple script such as:
wihle `pgrep mpirun` != ""
ompi-checkpoint `pidof mpirun`
sleep 5

Currently, there is no mechanism to checkpoint every X minutes in Open
MPI.
As mentioned below you can use a script to initiate the checkpoint
every X minutes. Alternatively it should not be too difficult to add
such a feature to Open MPI. If enough people would be interested I can

Checkpoint/restart in Open MPI supports TCP, Shared Memory,
Infiniband, and Myrinet interconnects (possibly others, but they have
not been tested) [1]. Is this what you are looking for?

This actually is a concern addressed to all the authors/OpenMPI
contributors. The links to IEEExplore or ACM requires a subscription
which, unfortunately, not all the list subscribers have.
Would it be a copyright violation to post the actual paper/article to
the list instead of just a link?

Dear Josh,
I am sure it will definitely be good because if someone is using
OPEN MPI for checkpointing his application, he will not want to sit and
checkpoint the application manually; and this can be a real pain if its a long
running application.
I would imagine an automatic resta

I'm using openmpi (1.3.2) to run on 3 dual processor machines (running
linux, slackware-12.1, gcc-4.4.0). Two are directly on my LAN while
the 3rd is connected to my LAN via VPN and NAT (I can communicate in
