Bugs, broken codes, or system failures require added time for troubleshooting and increase the risk of data loss. LLNL has addressed failure recovery by developing the Scalable Checkpoint/Restart (SCR) framework.
News Item
With SCR, jobs run more efficiently, recover more work upon failure, and reduce load on critical shared resources.
