    Hi all,
    I noticed the BLCR User Guid says:
    "You may restart a program on a different machine than the one it was 
    checkpointed on if all of these conditions are met (they often are on 
    cluster systems, especially if you are using a shared network 
    filesystem), and the kernels are the same."
    I'm trying to implement such function on our Linux cluster:
    - Node: IBM x3550 - 2 x Intel 5160 Xeon dual core
    - O/S: Scientific Linux 4 (similar to RHEL4)
    - File System: GPFS
    - Compiler: GNU 3.4.5
    - BLCR version: 0.5.0 and 0.6.1
    I can restart checkpointed file on the same node but failed on another 
    one. All work nodes using the same image and shared file system.
    The error message is: "Segmentation fault"
    Anyone knows why my restart fail and how to implement cross node restart 
    on the cluster? Thanks
