Gleb,
I am trying to use BLCR as well. What levels of OpenMPI, OFED, and BLCR
are you using? I can get a serial checkpoint/restart to work but not the
parallel case. I built my system using OFED 1.3.1, OpenMPI 1.3.1, and BLCR
0.8.1-1. I also used your same BLCR configuration options for OpenMPI.
Thanks,
Pat

Fixed this, not all paths were in variables. Sorry.
