Subject: [OMPI users] ompi-restart using different nodes
From: Jonathan Ferland (jonathan.ferland_at_[hidden])

Hi,

I am trying to use BLCR checkpointing in mpi. I am currently able to run
my application using some hostfile, checkpoint the run, and then restart
the application using the same hostfile. The thing I would like to do is
to restart the application with a different hostfile. But this leads to
a segfault using 1.3.3.

Is it possible to restart the application using a different hostfile (we
are using pbs to create the hostfile, so each new restart might be on
different nodes), how can we do that? If no, do you plan to include this
in a future release?

thanks
