OpenLava[1] is an open source workload job scheduling software for a cluster of computers. OpenLava was derived from an early version of Platform LSF.[2] Its configuration file syntax, API, and CLI have been kept unchanged. Therefore OpenLava is mostly compatible with Platform LSF.
OpenLava was based on the Utopia research project at the University of Toronto.[3]
