Subject: [OMPI users] Checkpoint and restart
From: Gabriele Fatigati (g.fatigati_at_[hidden])

Dear OpenMPI developers,
i have some questions about application robustness. , I have read that in
OpenMPI development trunk version will have implemented techniques of
checkpoint and restart. But, i need to know ho this techniques works. Are
they internal functions to insert in my code, external tool or other?

And, when i restart my application, is it possible to modify the initial
number of processors?
