Blogging Research
As noted in the textbook chapter, multi-core technology may not necessarily make applications run faster. Research real-life computing environments that are expected to benefit from multi-core chips and briefly explain why. Cite your academic sources and be sure to include your name in the comments.

Apple uses multicores in its latest processors. They claim multicores solve both the power and heat problems of older technologies.

Intel uses dual-core technology to run business servers. Dual-core technology increases the server's processing capacity and allows problem solutions to be applied to larger problems. The company combines the already powerful dual-core tech with the equally powerful Hyper-Threading technology. By using these two technologies in tandem the number of threads per socket is doubles. These multi-core servers provide 53% more performance in the same physical space. Also, power has been powered up providing 43% more performance per watt. Ultimately performance is out of this world and even larger than could have been imagined even ten years ago.

AMD states that their Quad-Core AMD Opteron processors has an uncompromised design and gives unprecedented performance per watt.
AMD says that this new powerful processor has several advantages over other server cpu's which includes optimal virtualization, enhanced power efficiency, investment protection, and overall outstanding performance.
I wonder if these new multicore can really hold the weight that's been placed on their shoulders, and how other companies plan to answer to such a cliam.

My experience has been that both Linux and Unix machines have more robust memory management than Windows. I need to research the claims, probably on the net. I am posting this to see if I can get it up.
Vebders are offering more processors per chip. The computer then knows how to divide processing jobs between the two or more processors. But we have a problem. Most applications dont have the capibility of using multi-core chips to their full potential. So contrary to popular belief, just because you have multi-core processor doesnt mean your system will run any faster.

Many businesses have benefited from the multi-core chip processor. Although the multi-core chip processor does not improve the performance in computers by increasing the speed of processing, energy is used much more effeciently. This way companies get more “performance per watt” for the expenses they pay for power consumption which has become one of systems manager's top five concerns.

Google has done it with the blogging, by creating multiple categories of pages. Google has over 30 categories to chose from and selective languages. Blogging has become a way of communication beside e-mail, phone, and postal. One also can do blogging on the cell phone beside texing.
from what i have read on the Multi-core processor there are a number of advantages available. one such advantage is that it allows the cache coherency to operate with a higher clock rate than if it had to signal to another off-chip.
unfortunetly the OS must go through major adjustments to all existing software just to maximize the utilization of the resources that the multi-core provide.

MULTI-CORE
Multi-core processors solve several problems that ordinary processors have
1. they take up less board space per processor,
2. they require shorter interconnection, and
3. they allow slower clocking, which uses less power, which creates less heat, needing less cooling to survive.
These characteristics allow for parallel processes, such as cache or memory access during CPU operation in desktops:

/quad-core-06.pdf
pp.3,5,7
They also allow for easier multi-tasking, such as virus checking during I/O for a desktop or multiple clients for a network server:

p.3-5
Another application is internet telephony, which is the subject of a webinar later this month:

Multi core processing units are most widely used in computers from intel and amd and gaming consoles. In todays high graphic video game console systems there are many processors working. The reason for this is because they can heave several processors working that many times faster than 1 processor. The multi processors can each be ran at a lower speed and outperform a single processor while also keeping the system cooler and saving the life of the processor.

In terms of competing technologies for the silicon die area, multi-core design will prove CPU core library designs and produce a product with lower risk of design.
The general trend in processor development has been from multi-core to many-core: from dual-, quad-, eight-core chips to ones with tens or even hundreds of cores; see manycore processing unit. In addition, multi-core chips mixed with simultaneous multithreading, memory-on-chip, and special-purpose "heterogeneous" cores promise further performance and efficiency gains, especially in processing multimedia, recognition and networking applications. There is also a trend of improving energy efficiency by focusing on performance-per-watt with advanced fine-grain or ultra fine-grain power management and dynamic voltage and frequency scaling

Many engineering teams benefit from multi-core chips. Software programs such as CAD, CAE, and PLM can handle multiple, complex tasks simultaneously. This allows engineers to save money by eliminating costly specialized supercomputers.

The problem with using multi-core processors today is not that they are inferior to single core in any way, but that much of the existing software on the market doesn't support the resources that a multi-core will give you. This trend is changing however, as most every computer on the market today has at least a dual-core processor. It is not the processors, but some of the currently existing software that will not work optimally with them.
An example of an environment which would benefit from a multi-core processor would be gaming. Many game companies are now supporting multi-core processing in the computer games they release.
