Large-scale systems like Sequoia allow running small numbers of very large (1M+ process) jobs, but their resource managers and schedulers do not allow large numbers of small (4, 8, 16, etc.) process jobs to run efficiently. Cram is a tool that allows users to launch many small MPI jobs within one large partition, and to overcome the limitations of current resource management software for large ensembles of jobs.
