Lustre Is the Logical File System for Exascale [24315]
Maturity, Stability, Object Store-based: Much of the Work Is Already Done
The clock is running on the goal to stage an exascale technology demonstration capable of handling a peak of 400 petaflops by 2015. This is more data than a single stream can deliver, so the search is on in the HPC community for a solution to these I/O demands. The hardware approach, writes Brent Gorda, Whamcloud CEO and President, in his HPCWire article "Why Lustre Is Set to Excel in Exascale," -- boosting performance on the single unit and going widely parallel -- will work until power limitations and parallelism issues become an impediment. Gorda enthusiastically nominates the Lustre file system to fill the software side of the equation. Lustre, he continues, based on an object store, has the necessary fundamental architecture for exascale, which the HPC file system technologists think will be based on an object store approach. It might work, Gorda continues, to introduce new file types to Lustre that will provide exascale object storage semantics internally. While this will require development of the underlying object model, Gorda points out that it holds the promise that the same file system will be able to support the full range of applications from (legacy) POSIX through to exascale. Finally, under development since 1999, Lustre has the maturity and stability that developers seek as the starting point for rapid and diverse development, Gorda concludes.

Sun Blade Servers Provide Foundation for Red Sky/Red Mesa Supercomputer [24144]
Sandia National Labs Achieves Tenfold Increase in Computational Capacity, Cuts Energy Consumption, Cost by 77 Percent
RedSky/Red Mesa one of the world's fastest and most energy efficient supercomputers, housed at Sandia National Laboratories, is powered by Oracle's Sun Servers that include Sun Blade Modular Systems that employ the Sun Cooling Door System and Oracle's network fabric as foundational technologies. With this architecture in its supercomputer datacenter, Sandia has realized reductions in energy consumption and cost by 77 percent and achieved a peak performance of more than 500 trillion mathematical operations per second. The Sun Cooling Door removes 90 percent of the heat load on servers and saves 5 million gallons of water per year. Using the Lustre file system running on Sun storage servers and on Sun disk arrays, Sandia increased their storage capacity and IO performance using an Infiniband connected file system with over 6PB in capacity that delivers more than 20GB/Sec in throughput.

New Oracle Names for Sun Software [23742]
With Links
Many of the software products produced by Sun Microsystems have been rebranded since the Oracle acquisition. This is a useful table mapping the old names to the new names along with links to the Oracle (or other) home pages for those products.

An Orphan No Longer, Lustre Gets Backing of Non-Profit Corporation [23616]
Open Scalable File Systems, Inc. Adopts Sun's Former Solution
Lustre has been adopted by a consortium of some of the biggest names in HPC computing, reports Michael Feldman in HPCwire. Open Scalable File Systems, Inc. (OpenSFS), backed by Cray, Data Direct Networks, Lawrence Livermore National Laboratory (LLNL) and Oak Ridge National Laboratory (ORNL), is the adoptive entity. The organization's mission is to bring together the stakeholders for high-end scalable file systems and provide a formal structure for moving the associated software forward, Feldman writes.

Could Oracle Be Losing Its Lustre? [23557]
Perhaps Ony Larry Ellison Knows for Sure
This much is known: Lustre 2.0.0 is now GA and available for download but in a community-only release. Upgrades to 2.0.0 are not supported for production 1.8.x sites. Lustre 2.0.0 provides support for OEL 5, RHEL 5, SLES 10 and 11 (client only), and Fedora 11 (client only). This release offers a number of significant features and enhancements, including Changelogs, Commit on Share, Lustre_rsync, and Size-on-MDS (preview). Lustre 2.0.0 supporting documentation includes the Operations Manual, Release Notes, and Change Log 2.0. As to Lustre's ultimate future ... more will be revealed.
