The SCR software framework provides efficient, scalable checkpoint/restart capability for simulation codes, ensuring faster time to solution and allowing scientists to focus on the science. SCR caches checkpoint data in storage on the compute nodes of a Linux cluster to provide a fast, scalable checkpoint restart capability for MPI codes.

In this video, LLNL’s Kathryn Mohror explains how SCR works. Physicist Denise Hinkel then discusses how SCR has impacted simulation capabilities at the National Ignition Facility.
