A software product called the Scalable Checkpoint/Restart (SCR) Framework 2.0 recently won an R&D 100 Award. SCR enables HPC simulations to take advantage of hierarchical storage systems, without complex code modifications.

In this podcast episode (12:18) produced by the Exascale Computing Project, LLNL’s Kathryn Mohror and Elsa Gonsiorowski talk about what SCR is and does, the challenges involved in creating it, and the impact it is expected to have on HPC performance.
