Hello,
There are a few things you need to do to build Open MPI with
Checkpoint/Restart support. By default Open MPI is configured without
checkpoint/restart support.
1) Make sure you have BLCR successfully installed and loaded on your
system(s)
2) configure Open MPI with the "--with-ft=cr" option, which enables
checkpoint/restart fault tolerance
Note: you may also have to specify the install directory of BLCR
with the "--with-blcr=/path/to/blcr"
3) make and make install
The resultant build will have support for checkpoint/restart and the
tools (e.g., ompi-checkpoint, ompi-restart) will become available.
Looking at the documentation it doesn't seem to include these steps.
I'll fix that later today, and post and updated file to the wiki.
Sorry about that. :(
Hope this helps,
Josh

Hello,
I'm Hiep, I'm trying to use checkpoint/restart feature in Open MPI.
I had read information about this feature in https://svn.open-
mpi.org/trac/ompi/wiki/ProcessFT_CR and Open-MPI-FT-CR-Draft-
v1.pdf. I had built Open MPI from "trunk" which gotten by Subversion.
But I don't know how to enable checkpoint/restart fault tolerance
in Open MPI.
So that, I get this error when I try this command: ompi-checkpoint.
bash: ompi-checkpoint: command not found
I want to ask you how to build and use checkpoint/restart feature
in Open MPI.
Please tell me in details, I'm a new user.
Thanks!
