[mvapich-discuss] cr_restart does not work when you change the hosts file

[Xavier Besseron]

Hi Alexandr,

Please make sure that you follow all the configuration steps under the
"Basic Checkpoint/Restart" section of the userguide:
http://mvapich.cse.ohio-state.edu/support/user_guide_mvapich2-1.7_alpha2.html#x1-530006.9.1

Because you want to restart on a different node, I guess you need to
disable prelinking on your nodes.
You can find further details about this here:
https://upc-bugs.lbl.gov//blcr/doc/html/FAQ.html#prelink

Let us know if it solves your issue.

Thanks,

Xavier
