    Hi:
    
     I've checkpointed/restarted jobs on different CPU's
    before for example:
    I've checkpointed on a AMD processor and
    restarted on a xeon processor.
    
    It does not seem to work all the
    time however. I just did a checkpoint on a XEON and
    tried to restart
    on a AMD and I got a segmentation fault. trying to restart the
    application.
    
    My question is under what  circumstances I
    can restart on a different x64 CPU.
    How can I build my code so I
    won't have problems with this. (Or should it be working).
    
    I am
    using blcr 0.8.0 on  2.6.9-55.ELsmp kernels.
    
    
    With
    Blessings
    and Best regards,
