Can I still get an Energy Efficient Free Lunch?
By Clay Breshears (Intel) (196 posts) on February 17, 2012 at 3:49 pm
Comments (1)
When the semiconductor industry was turning to multicore chips and lowering clock rates, Herb Sutter wrote a seminal article entitled "The Free Lunch is Over: A Fundamental Turn Toward Concurrency in Software." Up to that point software developers relied on the increasing clock speeds (the "free lunch") to give their software a boost in the next generation [...]

Have we already hit the maximum number of cores that can be put in our processors? Or have the needs of the user and developer communities been served at sixteen cores?

Using Amdahl's Law for Energy Efficient Performance Estimation?
By Clay Breshears (Intel) (196 posts) on January 26, 2012 at 1:24 pm

While trying to find an answer to my previous question, I stumbled across the paper "Extending Amdahl's Law for Energy-Efficient Computing in the Many-Core Era" (Computer, Dec. 2008, pp. 24-31) by Dong Hyuk Woo and Hsien-Hsin S. Lee (Georgia Institute of Technology). The title had me thinking that this might be an investigation into finding [...]

A few weeks back I went on eBay and got myself two Pogoplug devices. Very nice little media and file sharing devices, you plug storage in the USB ports and you get access to the data anywhere on the internet. The devices are not expensive at all and very functional. One of the things that [...]

Say your boss comes to you and tells you to ensure that the software project you are working on is energy efficient. (Go ahead, I'll wait while you say it.) There are all kinds of ideas to be found on the Power Efficiency Community site on how to accomplish this assignment. What I'd like to [...]

With this post, I want to cover how Meshcentral.com powers up sleeping computers. As many of you know, you can go on the web site, see all your computers and select one or many and remotely powered them off, reset them, etc. These operations are fairly simple, just tell the mesh agent to instruct the [...]

Without a doubt, one of the most exciting developments in the tech world for 2011 was the introduction of the Ultrabook. We put a reference design out there and OEMs took it and ran with it. Most of the models that arrived were slim, sleek, powerful and yet power-efficient. I brought one of the current [...]

Accessing Intel® Power Gadget from Intel® Energy Checker SDK
By Jun De Vega (Intel) (2 posts) on December 15, 2011 at 10:00 am
Comments (0)
Intel® Power Gadget 2.0 can be associated with the Intel® Energy Checker SDK (Intel EC SDK). Used as an ESRV* DAQ module**, the Intel® Power Gadget can provide processor average power (Watt), cumulative energy consumed (Joule) and instantaneous frequency (MHz) as counters. These counter’s values can then be read by any application using the SDK API or [...]

I saw an announcement of the Gordon supercomputer in an online Wired article. What made the new installation at the San Diego Supercomputer Center (SDSC) noteworthy wasn't the size of the machine or that the machine debuted at #48 on the TOP500 list. No, it was the fact that Gordon is the world's first supercomputer [...]
