Sun Grid Engine 6.2 Update 2 is now available with new features, scalability improvements and memory foot print reductions for HPC clusters, and bug fixes. The Sun Grid Engine software provides advanced resource management and policy administration for UNIX and Windows environments that are composed of multiple shared resources. The Sun Grid Engine software enables users to apply resource management strategies to distribute jobs across a grid. Users can submit millions of jobs at a time with the system supporting clusters of up to 63,000 cores.

New Features in SGE 6.2 U2

• GUI Installer: the new GUI installer simplifies the installation process of a whole cluster interactively.

• Microsoft Windows Vista Support: Support is now offered for Microsoft Windows Vista Enterprise and Ultimate Edition, Windows Server 2003R2 and Windows Server 2008 (both 32- and 64-bit versions).

• Job Submission Verifier (JSV): This script or binary can be used to verify, modify, or reject a job during the time of job submission or on the master host. JSVs allow rules to be defined to determine which jobs are allowed to enter into a cluster and which jobs should be rejected immediately.

• Consumable Resource per Job: Consumable complex attributes can now be configured as per job. Such consumables are consumed as requested and are no longer multiplied by the requested slots. This makes resource requests for parallel jobs much easier to define, especially when using slot ranges.

• Jemalloc Library (on Linux x64): Linux distributions (x64 platforms) come with a default memory allocator library which is not as efficient as the open source jemalloc memory allocator library also used by the Firefox browser. Update 2 replaces the native Linux malloc library with the jemalloc library on x64 platforms. This has a positive effect on the master host performance in large and high throughput Sun Grid Engine clusters on Linux x64 and reduces the memory footprint up to 20% leading to a significant performance increase.

"As always, you may test this release in parallel with your old cluster to try out the new features," advises Sun's Lubomir Petrik. "Optionally, you may use the upgrade procedure (clone configuration method) to install SGE 6.2u2, while keeping all your other cluster configuration settings. See the upgrade video. While the video shows an upgrade from 6.1 to 6.2, it will work the same way for cloning any 6.0u2 or later to 6.2u2."
