Let's say I have an MPI application running on several hosts. Is there any
way to checkpoint this application without having a shared storage between
the nodes?
I already took a look at the examples here
http://www.osl.iu.edu/research/ft/ompi-cr/examples.php, but it seems that in

int* coords;
}point;

compilers as well. In many cases openmpi fails test 1 and perhaps some
of the others. Openmpi is not alone; the version of mvapich on my
cluster fails a simple "CNTRL
