[PCW] Multicore Myths Revealed - Page 2

Thread Starter 
it just doesn't seem to be a hardware issue at all
and we have been positioned to see it as such through advertising.
fact is the hardware rocks...
software has not kept up, period.

Microsoft and Intel joined together to build two research centers focused on parallel computing and multicore programming research. The companies have agreed to offer a combined $20 million to two universities to fund the centers.
Microsoft and Intel plant to establish Universal Parallel Computing Research Centers at two universities, UC-Berkely and the University of Illinois at Urbana-Champaign. Both companies have agreed to invest the grant over a period of five years.
"This is a once-in-a-career opportunity to recast the foundations of information technology and influence the entire IT industry for decades said David Patterson to come,",
(Erm... excuse me Dr. David, "recast foundations?"; don't I arleady have this technology in my desktop?)

UC-Berkeley professor of computer sciences, in an announcement. "We are excited and proud to be a part of this ambitious effort."
The centers will promote industry/university collaboration in solving problems that face the IT industry.
The centers will be focused on parallel computing and multicore programming research and will help make new software technologies available to mainstream users. According to Microsoft and Intel, software developed by the centers will be made available to the vast technology community for further refinement
("parallel and multicore programming research...available to the vast technology community for further refinement", sounds like it doesnt exist. Could this be true?)
According to Microsoft and Intel, the shift to multicore processors has made it imperative to further refine our current methods of programming as well as creating new methods. Software optimization is necessary in order to take advantage of the multiple cores found on modern CPUs.
(Can this mean the proper instructions for parallel and multicore processing has not existed since the 8xx series?)
Microsoft and Intel won't be the only ones providing for the research centers. UC-Berkely researchers are also applying for a UC Discovery Grant, which matches industry grants through state and university funding. The University of Illinois committed another $8 million to the project.
Microsoft says the two universities were chosen out of a pool of 25 high-tech and leading computer science universities.

E8400 or Q6600?
I recommend Q6600, nearly almost the same price. I see a lot of places selling it for about $229-$250, why not spend a little more for it to last longer. Especially if you don't upgrade a lot, a quad will last longer than a duo.

since 2001 or so, the steadily climbing speeds have suddenly flattened, and it doesn't take a lot of empirical evidence to see this. In August of that year, the average CPU speed in a high-end desktop or low-end server was around 2GHz, meaning that six years and four iterations of Moore's Law later we should be seeing processors at around 16GHz or so. A quick glance through online product descriptions from any major PC supplier will show that similar-ranged machines are hovering around the 3.0-3.6GHz range, more than a bit short of that 16GHz mark
Clock speed is NOT the same as raw performance! If I make a really inefficient processor that has a clock speed of 10GHz, it would get totally pwnd by a Conroe.

The ONLY measurement of performance is execution time. We could arbitrarily force every processor to run at 3GHz, and still show a large improvement in performance over time by simply building better architectures.

I'm sick of this clock speed bs, it means nothing.

True to a point but you can get the processes to run faster by increasing clock speed or adding cores. Its just that the level of performance that we should be seeing by doing such isnt what it should be. Hence why a 8400 at 4.5ghz still rocks when running against a quad at 3.2ghz when it should be getting its ars kicked.

This has sparked resurgent interest in new ways to deal with concurrency, ranging from new language-based approaches (e.g., OpenMP or JR)
YES! JR WINS!

JR is a language based on Java, but with high-level concurrency features added to it. I actually know the professor who made this language, as I just took a class from him in which he taught us JR!

Also, I will be working on JR research with him next quarter.

All programmers should check it out:
