Intel Xeon 5500 (Nehalem EP) NUMA Versus Interleaved Memory (aka SUMA): There Is No Difference! A Forced Confession.

I received an interesting email recently from a reader that takes offense at how I dare to discuss the differences between Intel Xeon 5500 (Nehalem) systems operating in NUMA versus SUMA/SUMO mode. One excerpt of the email read:

…and I think you are just creating confusion and chaos to gain popularity with your NUMA versus non-NUMA stuff. We tested everything we can think of and see no difference when booted with NUMA or non-NUMA…

I don’t doubt for one moment that the testing performed by this reader showed no performance differences between NUMA and SUMA because I have no idea whatsoever what his testing consisted of. And, besides, Xeon 5500 Nehalem EP is one extremely nice NUMA package. That is, when running non-NUMA aware software on this particular NUMA offering you can rest assured that you won’t likely fall over dead from NUMA pathologies. That’s good, but does that mean there really is no difference when booted in the NUMA versus SUMA? Hardly! more. . .

FINANCE: Firm Escorts Nanotech Energy Startups through 'Valley of Death

The article spotlights an early-stage venture fund, called Nanoholdings, that says it exists to help nanotechnology ventures get through the "Valley of Death", the hostile gap between laboratory and market - a place where startups collapse and die due to a lack of cash. The company, based in Connecticut, United States, was launched in 2003 and has already invested US$15 million in 14 nano-energy companies in the United States and the United Kingdom. Its partners work with scientists starting companies and help them to develop business models, find employees, identify potential buyers more . . .

Microsoft submits source code for Linux kernel

In a move that has Linux backers hailing it as an endorsement of the open-source development model, Microsoft on Monday submitted source code for inclusion to the Linux kernel under a GPLv2 license. The code consists of four drivers that will provide hooks for any distribution of Linux to run on Windows Server 2008 and Microsoft's Hyper-V hypervisor technology. more . . .

ANSI Nanotechnology Standards Panel Meeting To Be Held September 9

Washington, DC | Posted on August 13th, 2009Scheduled for the afternoon of September 9, 2009, the ANSI-NSP meeting will provide an opportunity for interested stakeholders to learn about ongoing nanotechnology standardization activities as well as to discuss particular areas of focus needed for nanotechnology standards.

"The growing number of nanotechnology-based industrial products and services has created a critical need for standards to support trade in this arena and to be used in protecting the environment and the health and safety of consumers and workers," said Clayton Teague, chairman of the ANSI-NSP and director of the National Nanotechnology Coordination Office (NNCO). "But in order to move these standards forward, we need active engagement by technical experts from academia and significant industry sectors that are working to advance this important and promising technology."

Formed in 2004, the ANSI-NSP serves as a cross-sector more . . .

Eight-year-old critical bug found in Linux kernel

Developers have issued an update to patch a critical bug that has just been discovered in the Linux kernel. This serious vulnerability puts the kernel--and the entire server by extension--open to being taken over via local privilege escalation. You can check out the more . . .
