With SCR, jobs run more efficiently, recover more work upon failure, and reduce load on critical shared resources.

Project

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.
