[mpich-discuss] How to get checkpoint-file

[Darius Buntinas]

It seems that you did things correctly.  Did you recompile your 
application (cg) with the new mpich2?  The make sure the 
/tmp/app.ckpoint directory exists (not just /tmp but /tmp/app.ckpoint).

Note that this version of MPICH2 is still an alpha version, and we're 
still working the bugs out of it.  We appreciate that you're giving this 
a try.
