Sweet 16?
Опубликовано Clay Breshears (Intel) Размещено 06.02.2012 4
I just saw the article "AMD calls end to core growth on server chips" at Techworld.com. The gist of the article is that AMD has decided to produce server chips with no more than 16 cores. There were some interesting future directions outlined and hinted at by the end of the article, too. What see...
Using Amdahl's Law for Energy Efficient Performance Estimation?
Опубликовано Clay Breshears (Intel) Размещено 26.01.2012 1
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 tha...
How would you define "Energy Efficient"?
Опубликовано Clay Breshears (Intel) Размещено 18.01.2012 0
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 know ...
Parallel Programming is easier than separating 2 corks
Опубликовано Clay Breshears (Intel) Размещено 06.01.2012 2
I've known Prof. Tom Murphy for a few years now. Whenever we were at a conference or other event together and had dinner, he invariably would ask the wait staff if they had two corks he could have. If the place served wine, it wasn't too difficult to find two corks that were the same size or clos...
Can <em>your</em> phone SEE what you're saying?
Опубликовано Clay Breshears (Intel) Размещено 16.12.2011 5
Since I don't have a smartphone (and am not in the market for one), I don't typically care what new features get put into the latest models. That is, unless it is cool and interesting. When I first saw commercials for the Apple iPhone S and Siri, I thought it must have been a recreation of the te...
As fall Idaho twins, so falls Twin Falls, ID

If you've read Kathy's blog and Show Notes for Parallel Programming Talk #130, then you know the sad news. This was the last show we'll be doing. Kathy and I are moving on to different duties within Intel. Ironically, over the last three months I've had quite a few people tell me that they had ju...
MIC: Stepping-stone to Quantum Computing?
Опубликовано Clay Breshears (Intel) Размещено 14.12.2011 5
I was reading Quantum Computing for Computer Scientists by Noson S. Yanofsky and Mirco A. Mannucci while I was on the treadmill last night. I started out reading the description of Shor's algorithm (for factoring integers) and thought that implementing this on a classical computer (in parallel, o...
FLASH: Why haven't we seen this sooner?
Опубликовано Clay Breshears (Intel) Размещено 12.12.2011 3
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...
It's here! The Intel Guide for Developing Multithreaded Applications
Опубликовано Clay Breshears (Intel) Размещено 27.10.2011 13
Okay, so it's not something that I would promote as "New & Improved"  with big splashy TV commercials, like some laundry detergent or kids' sugary drink. I would be more likely to skip the trumpets and play a fanfare on a kazoo instead. Even so, I'm excited to announce that the Intel Guide f...
The slings and arrows of outrageous fortune?

I knew this day was coming, but you're never prepared for it. I was in Portland, OR, for an internal Intel conference. Before the meeting got started, I arrived early and decided to browse Powell's Books. The technical store's location has changed and the name seems to now be Powell's #2, so I wa...
