The New Intelligent Design

Open the #pod bay doors, @HAL

Despite over promising the likes of HAL 9000 the Artificial Intelligence (AI) community has been making steady progress. Indeed, the famous Watson Jeopardy Experiment was a great demonstration of the coming era of "smart systems." Other examples are Apple's Siri, and smart search engines (including Google, which seems to be getting smarter about its search results each year.)

All of these efforts have several things in common; AI based software, piles of data, and racks of commodity hardware. Popular conversations include terms like business intelligence, knowledge discovery, Big Data, Hadoop, and other new buzz words. Is this yet another fad being oversold by the marketing types or is this a game changing set of technologies that will shape how we interact with almost everything we touch?

The Core-Diameter

Does the speed of light limits how big a cluster we can build

Recently, I started to think about the physical limits and how these limits would effect the size of clusters. I did some back of the envelope math to get an estimate of how c (the speed of light) can limit cluster size. As clusters continue to grow in size and the push toward exascale performance, the following analysis may become more important in designing HPC systems. I want to preface this discussion, however, with a disclaimer that I thought about this for all of 20 minutes. I welcome variations or refinements on my ciphering.

Supercomputers: Getting it Right and Wrong

Much has changed in the supercomputing arena. Even you can get in the game!

Recently, Sebastian Anthony wrote an article for ExtremeTech entitled What Can You Do With A Supercomputer? His conclusion was "not much" and for many people he is largely correct. However, there is deeper understanding that may change the answer to "plenty."

He was mostly right when talking about the worlds largest supercomputers. Indeed, one very workable past definition of a supercomputer was "any computer that had at least a six digit price tag." In the past, that was largely true and created a rather daunting barrier to entry for those who needed to crunch numbers. The cost was due to an architectural wall between supercomputers and the rest of computing. These systems were designed to perform math very quickly using vector processors. It all worked rather well until the cost of fabrication made creating your own vector CPU prohibitively expensive.

A Smidgen of Quantum Computing

Does a real instant password cracking quantum computer exist, or are we just at the beginning of the next revolution in computing?

(Note: The first half of this article was published last year at Linux-mag.com, however the second half was never published. Both parts have been updated and are presented below.)

Recent news by IBM describes very good progress toward the creation of real quantum computer. The work helped solve the stability problem associated with many quantum computer designs. There have been other quantum computer announcements over the last year. In May of 2011 a press release by DWave Systems proclaimed D-Wave Systems sells its first Quantum Computing System to Lockheed Martin Corporation. The press release created a bit of a stir in the quantum computing world and as with any new technology there is often some confusing (some deliberate) around actual milestones and press releases.

All Your BASH Are Belong To Us

From the "secret sauce that tastes bad" department

Many Linux/Unix programmers are not aware that a battle over Bash scripts is currently raging in a Kansas courtroom. A Linux cluster vendor, Atipa Technologies is claiming all the Bash scripts they shipped to customers contain trade secrets and were stolen by former employees. Should this issue be decided in Atipa's favor, the fundamental idea of shared and open software could be blanketed by the simple claim of trade secrets.
