Silver is an advance reservation based meta-scheduler.
It is a system which allows a site to combine the resources of multiple high performance computing systems providing a common user interface to all resources. Silver also provides intelligent load balancing across the systems, and advanced co-allocation functions allowing a single job to span multiple homogeneous or heterogeneous computing systems. The benefits to such a system are clearly evident and come at multiple levels. Users are no longer frustrated by the requirement to learn a new interface for each compute system. Silver is able to load balance across the machines resulting in better overall utilization and better turnaround time.
