Thanks Josh.

I will give a go.

Re: [OMPI users] BLCR + Qlogic infiniband

[Josh Hursey]

With that configure string, Open MPI should fail in configure if it does
not find the BLCR libraries. Note that this does not check to make sure the
BLCR is loaded as a module in the kernel (you will need to check that
manually).

The ompi_info command will also show you if C/R is enabled and will show
you if the 'blcr' 'crs' module in the listing at the end. That is probably
the best way to see if the build includes this support.

Re: [OMPI users] Live process migration

[Josh Hursey]

Process migration was implemented in Open MPI and working in the trunk a
couple of years ago. It has not been well maintained for a few years though
(hopefully that will change one day). So you can try it, but your results
may vary.

Some details are at the link below:

Thanks Jaroslaw,

I will try it asap, it appears that DMTCP at sourceforge.net site is down
at the moment.

Re: [OMPI users] error configuring OpenMPI 1.6.3 with gcc 4.7.2

[Joseph Farran]

Hi All.

I was away all of last week so I am late here. A note that I was able to 
compile OpenMP 1.6.3 with gcc 4.7.2 successfully.

I built gcc 4.7.2 by hand with binutils-2.23.1, mpc-1.0.1, mpfr-3.1.1 and 
gmp-5.0.5.

Thanks. This is obviously (now) a problem with my gcc build which isn't 
appropriate for this list. I'll re-visit this and post a solution once I've 
(hopefully) got this working. I don't have any shared libraries (*.so.*) in my 
gcc tree so something went badly wrong ...

Thanks for your help.
