[mpich-discuss] How to get checkpoint-file

[Darius Buntinas]

You should reconfigure mpich2 1.3a2 with those options, then do
   make clean
   make
   make install
Then recompile your applications.

To run your app with checkpointing do (all on one line)
   mpiexec -n 11 -ckpoint-interval 5 -ckpoint-prefix /tmp/app.ckpoint ./cg

Let us know how that works.
