+The Scalable Checkpoint / Restart (SCR) library enables MPI applications to utilize distributed storage on Linux clusters to attain high file I/O bandwidth for checkpointing, restarting, and output in large-scale jobs. With SCR, jobs run more efficiently, recompute less work upon a failure, and reduce load on critical shared resources such as the parallel file system.
