    I am afraid that Moe (Morris) either misunderstood our discussions in 
    November, or is misremembering them.
    Our BLCR work has *not* yet done any integration with SLURM.  I 
    mentioned to Moe that we had been doing BLCR integration work with TORQUE.
    I also described to Moe work we had done to integrate SLURM on the 
    SiCortex platform with our Berkeley UPC compiler.
    So, with respect to BLCR+SLURM integration there are not any 
    "capabilities that exist today" from which to expand.
    I do share Moe's interest in you completing work on a SLURM plugin for 
    BLCR integration.  If there are any questions about BLCR that I could 
    answer for you, feel free to email our list: checkpoint_at_lbl_dot_gov.
