Paul RichThe Cobalt Scheduler and Resource Manager
Cobalt is a relatively lightweight batch scheduler and resource manager for clusters and large high performance computing systems. It currently supports the IBM BlueGene series of systems as well as the Cray XC40 series running CLE 6.0 as well as smaller general compute clusters. When available, Cobalt will use vendor-provided resource management tools, like ALPS or IBM's HLCS to help manage hardware. It also includes a simulator for modeling scheduler behavior with modified algorithms and functions and can be run off of prior accounting-log traces for testing new policies against production data as well as realtime-simulation modes for prototyping site policy filters and testing site-localization scripts in an offline environment.
