    thanks for your reply,right now i just want to test checkpoint with blcr+torque+openmpi,so i install torque+blcr on one node and configure the torque and blcr's bin/lib in my PATH and also followed your document on this subject http://www.clusterresources.com/torquedocs21/2.6jobcheckpoint.shtml
 and start pbs_server,pbs_sched and pbs_mom all on this node, I can run cr_checkpoint in command line with no root user.   I find someone has same problem http://www.mailinglistarchive.com/html/torqueusers@supercluster.org/2012-04/msg00159.html   so is his problem solved?I can not get his email address.

You need to install BLCR on all the compute nodes. I am assuming you're trying to run jobs on one of compute nodes and the node that has torque is not one of them. Check BLCR website for more information on adding path of blcr libraries to LD_LIBRARY_PATH.

Just making sure:
You have installed BLCR on all the nodes. Right?

it's sound like that i do not export BLCR library in my LD_LIBRARY_PATH,but i do setup my user enviroment and I can cr_run,cr_checkpoint and cr_restart in command line.I add $ENV{LD_LIBRARY_PATH} = "blcr_libpath" ; in checkpoint_script and the error still exist. I use blcr-0.8.4 and torque-2.4.16so is someone help,_______________________________________________
