Dear All,
I am trying to checkpoint am MPI application which has two processes
each running on two seperate hosts.
I run the application as follows:

and I trigger

Can you recommend me a good open source Grid simulation tool to execute

Dear All,
I am trying to get the process Id of Mpirun from within my MPI
application. When i use getpid() and getppid(), i get the PID of my application
and the PID of "orted --daemonize -mca..." respectively.
Is there a way to get the PID of the mpirun? In this case, it looks like it

I am trying to integrate DMTCP with openmpi. IF I run a c

HI,
I want to configure OPENMPI to checkpoint MPI applications using DMTCP. Does
anyone know how to specify the path to the DMTCP application when installing
OPENMPI.
Also, I wanted to use OPENMPI with SELF instead of BLCR. Is there any guide for
setting up OPENMPI with SELF?
Thanks a lot.

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
Daer All,
I have successfully comfigure OPENMPI with BLCR and id some test.
hover, i now want to do some testing with an Application Level checkpointng
tools. I tried using libckpt but could not install it.
Do anyone of you know any open source application level checkpointing tools
the /tmp directory instead of the $HOME directory?
Thank you
