+1 I would be interested in seeing support for this in Open MPI.

Re: [OMPI devel] CRIU checkpoint support in Open-MPI?

[George Bosilca]

Samuel,

Yes, all contributions are welcomed. It should be almost trivial to write a new 
backend in Open MPI to support what the kernel developers will agree to add as 
C/R capabilities. A good starting point to look at are the existing modules in 
opal/mca/crs.

[OMPI devel] CRIU checkpoint support in Open-MPI?

[Christopher Samuel]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hi folks,

I don't know if people have seen that the Linux kernel community is
following its own different checkpoint/restart path to those currently
supported by OMPI, namely that of the OpenVZ developers
"checkpoint/restore in user space" project (CRIU).

You can read more about its current state here:

 https://lwn.net/Articles/525675/

The CRIU website is here:

 http://criu.org/

CRIU will also be up for discussion at LCA2013 in Canberra this year
(though I won't be there):

http://linux.conf.au/schedule/30116/view_talk?day=thursday

Is there interest from OMPI in supporting this, given it looks like
it's quite likely to make it into the mainline kernel?

Or is better to wait for it to be merged, and then take a look?

All the best,
Chris
