OpenLava is an open source workload job scheduling software for a cluster of computers. OpenLava was derived from an early version of Platform LSF. 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.
OpenLava has gained significant development after forking out from Platform Lava, particularly in recent years.
Since fall 2015, the OpenLava development effort has been focused on improving scheduler performance and efficiency for high throughput workloads. In May 2016, OpenLava was benchmarked on AWS to schedule 1 million jobs with 100,000 concurrent job slots.

History
In 2007, Platform Computing (now part of IBM) released Platform Lava 1.0, which is a simplified version of Platform LSF 4.2 code, licensed under GNU General Public License v2. Platform Lava had no additional releases after v1.0 and was discontinued in 2011.
In 2011, former Platform Computing employee David Bigagli created OpenLava 1.0 by forking code from Platform Lava.
In June 2011, OpenLava 1.0 code was committed to GitHub.
In January 2012, OpenLava 2.0 was released with feature enhancements and bug fixes.

Commercial support
In 2014, a number of former Platform Computing employees founded Teraproc Inc., which contributes development and provides commercial support for OpenLava. Commercially supported OpenLava contains add-on features than the community based OpenLava project.
IBM Lawsuit
In October 2016, IBM filed a lawsuit alleging copyright infringement and trade secrets misappropriation against Teraproc. The complaint accused some of the company's founders of taking "confidential and proprietary source code" for IBM's Spectrum LSF product when they left, which was then used as the basis of the competitive product OpenLava. David Bigagli, the TeraProc employee who started the OpenLava project, posted a notice on GitHub announcing that downloads for OpenLava had been disabled because of a DMCA takedown notice sent by IBM's lawyers.
Bigagli later announced that the source code for OpenLava 3.0 and 4.0 would be taken down, while the source code of 2.2 would be restored in order to regain the GitHub repository and the openlava.org website, while claiming that the DMCA claim is fraudulent.
