Supercomputer niche chucks rocks at Nehalem

As niche supercomputer-maker SiCortex works on the next generation of its line and watches the IT marketing machine gearing up for Intel's impending Nehalem-based Xeon EP, the company says that Chipzilla isn't moving in the right direction for high-performance computing (HPC) workloads.

"The major improvement is in the integration of the memory controller, so you don't have to send all the memory traffic over the northbridge," says Jud Leonard, co-founder and chief architect at SiCortex. "But this only solves one of the three issues that Intel faces - issues that we have already solved. Intel hasn't done anything about solving the performance-per-watt problem, and they haven't done anything in terms of on-chip communication."

The future "Gainestown" Nehalem Xeon EP due on March 31 will run at between 1.86GHz and 3.2GHz with DDR3 main memory running at 800MHz, 1066MHz, or 1333MHz. TDPs will range from 60 to 130 watts.

The SiCortex super runs a variant of Gentoo Linux and has a tweaked version of the Lustre open-source clustered file system controlled by Sun and used by many supercomputer centers. Sun bought the company behind the Lustre project in September 2007.

EMC to open-source ViPR - and lots of other stuff apparently

ViPR is software storage controller tech that separates the control and data planes of operation, enabling different data services to be layered onto a set of storage hardware products - such as EMC's own arrays, Vblocks, selected third-party arrays, JBODs and cloud storage. The data services are typically ways of accessing data, such as file services, The open source software will be called Project CoprHD* and be made available on GitHub for community development. It will include all the storage automation and control functionality and be supplied under the Mozilla Public License 2.0 (MPL 2.0). Public supporting partners for CoprHD are Intel, Verizon and SAP.

Patent Pledges and Open Source Software Development

For all its benefits, one aspect of open source software does cause headaches: understanding the legal terms that control its development and use. For starters, scores of licenses have been created that the Open Source Initiative recognizes as meeting the definition of an “open source license.” While the percentage of these licenses that are in wide use is small, there are significant and important differences between many of these popular licenses. Moreover, determining what rights are granted in some cases requires referring to what the community thinks they mean (rather than their actual text), and in others by the context in which the license is used.

Open Source History: Why Did Linux Succeed?

One of the most puzzling questions about the history of free and open source is this: Why did Linux succeed so spectacularly, whereas similar attempts to build a free or open source, Unix-like operating system kernel met with considerably less success? I don't know the answer to that question. But I have rounded up some theories, which I'd like to lay out here. Read more
