Processors
One of the more recent developments in operating systems has been the use of multi-core processors. Once only used in high end systems, dual processors and even quad processors are now available in consumer grade machines. This article provides a good basic understanding of the dual core processor.
What advantages do you see in buying a multi-core PC? Blog on!

Duel core Processors are a huge development for the PC users! I first noticed the change of pace when I was ripping a DVD… (for personal use of course…)
If the software is written well to take avenge of the duel processors, you will get the speeds that you been waiting for. And the Quad cores will be even better; however, I do have some concerns about the heat that will come from these new improvements and the new bugs…
My HP dv2120us Notebook PC does get a bit warm (it has the AMD Turion64 x2 Mobile Technology) I also notice that it was bit buggy when using Acrobat PDF plug-in for web browsers when I was using Windows Xp and I was having to reboot because my system crash… these problems went away when I upgraded to Vista Home Premium…
In the past, I only bought Intel products, but took a chance when I saw the price for the AMD product. Right now, I do like the AMD product because of the stability that Vista gave it…

Intel Builds 80-Core, 1-Trillion Calcs Per Second Prototype Chip

Multicore processors can simultaneously execute multiple computing tasks; however, it is multithreaded applications that release the full power of multicore processing because they separate their tasks into independent threads. The National Instruments LabVIEW graphical development environment has been multithreaded since Version 5.0, which released in 1998. Therefore, virtual instrumentation applications, including data acquisition and modular instrumentation running LabVIEW, can obtain performance increases of up to 100 percent for multithreaded applications with parallel processes.

Some would say that AMD and INTEL have hit clock speed walls, but that not the case. The problem with winding up clock speeds is heat. At present the processor engine can operate at only so much RPM before the engine will seize. Heat is the enemy of any processor and high clock speeds mean high heat and that means errors. A Windows PC running at 10GHz isn't much good if it can't make it past booting up before crashing.
That heat comes from power. It takes a lot of juice to crank up a processor to high clock speeds and a processor with that much electricity running around the die is prone to noise. It's not audible noise like a high RPM cooling fan but electrical noise otherwise akin to interference. The pathways on a processor are microscopically close together. The more power that runs through these pathways due to the requirement of higher clock speeds means that there will be a small amount of electrical radiation from one pathway to the next. That leakage could corrupt the data in another pathway. Corrupted data means errors which means a program could get cranky. Dual or Quad core technology advances in recent years really made handling processes alot faster and affordable.

The way I see it, Dual-Core processors simply add more lanes to the highway where information travels. As the road widens, more parallel jobs can be performed, increasing the efficacy of the system, and decreases the time simultaneous jobs a re performed. I only wonder where this will lead us to!
I've worked with servers with 4 to 8 processors. I also, worked with stand alones and networked computers. The duel processor chip does come in handy as long as you use some forms of XP, Vista, and UNIX based systems. The duel core processor also allows these servers to act as an 8 to 16 processor systems. Now to the disadvantage...COOLING! You need to mount more fans or use a liquid cooling system (i.e. r-134 or water cool). Wait tell people over clock the processor talk about overheating. Soon the home computer will not be mobile but it will be compact and feasible.

I found the article interesting but this is really not my field. A few years back, Verizon used to run servers together to make our IT projects run better, "Calvin" and "Hobbes."

There are many advantages to increasing the number of processors. Now becoming available to common PC users, we're able to experience better performance, increased productivity, and enhanced performance. Never before was I able to run a virus scanner while performing other tasks, but the multi core processer will now allow no speed or performance delays. Many of the speed-sucking tasks can now be used without hesitation.

to all.......i am not in your class but i was, last spring 07, taking the same class.....
hi! manny....remember me from VB??
guys here's and ercerpt from the last semesters blog when i was taking op sys.....
ms perschbach....your great....thanks for all the insights.....looking forward to see again this fall 07...
anyways here it is......
multicore/singlecore....all these are interesting....I surely wanted to have all the latest gadgets available....but you've got to remember you always have to fit your needs and what you do.....as for me, so far i can live without the duocore or multicore....a singlecore so far satisfies me...unless some of you guys can convince me otherwise...remember money is a BIG consideration.....try me?
