Univa Grid Engine
Univa continues the development of the open source Sun Grid Engine project. For this the company hired the Grid Engine core development team. Based on the latest public sources of the project it contributed lots of bug fixes and other developments back to the public repository. It is hosted as a git project on github: github.com/gridengine. Since around version 8.0.0 no open source checkins.
The first version of Univa Grid Engine (version 8.0.0) was released in April 2011.
Univa provides commercial support for Grid Engine and offers other interesting products like UniCloud. Free 48-core limited version available for download.

Univa Grid Engine contains UniSight (web based interface) for accounting and reporting. Several new features like Job Classes, NUMA aware scheduler, Postgres Spooling, Improved Error Handling, new Resource Types, Support for GPU and other Co-Processors etc. are available. Additional improved (in comparison to the open source integration) support for Hadoop available.
Univa Grid Engine 8.2 comes with further scalability improvements (internally called: read-only threads) which splits the workload for job submission (write calls) and job status calls (read calls) internally in order keep up with future cluster sizes (currently big clusters have around 100.000s of cores). Because the Windows support in the past used a kind of Unix emulation layer, Univa Grid Engine is now natively ported to Windows. This allows you an easy integration of Windows submit and compute hosts in the Univa Grid Engine cluster. Dozens of improvements for parallel jobs (new parameters), clock resolution changes (from seconds to milliseconds) etc. are part of that release. Additionally a preview version of the DRMAA2 C API is included.
Since Univa was aquired by Altair the project has been renamed to Altair Grid Engine
