The Department of memory and the newly developed technology to enable programs to run more efficient multi-core processors.
IT 'parallelises' programs such as word processors, Web browsers, parsers language and graph algorithms, which is usually only used only one processor, or 'core', at one time.
The researcher, Dr. Devesh Tiwari can not be traditionally those programs that are running in parallel, comparing the process of brewing a pot of coffee in consecutive steps.
With his colleagues at the University of North Carolina, Tiwari developed a way to isolate and software functionality for memory management in a separate 'subject' from the rest of the workload.
And to the extent the functions of memory management, which involves the preparation of memory to hold the data or free memory that is currently in use, to include typically 30 percent of the volume of work in the program.
Because the thread 'memory management') (million tons) and can run on a core set different from the rest of the programs, researchers found 20 percent with the increase in the speed of open source software standards.
"Thread notifies the subject of calculation and memory management, said to be effective for the allocation and storage of data, and to notify the subject of computing where the storage space," explained Tiwari.
"In the same vein, when the calculation thread will no longer need certain data, it is a thread and memory management that could free up space storage-related."

computer updates every day
Core i7 is the name of a group of computer processors created by Intel. Issued in the autumn of 2008, and models of the Core i7 processors within the family include the Bloomfield, Lynnfield, and models of Clarksfield. Computer Core i7 processors to use what is known as Nehalem microarchitecture. In basic terms, this refers to the way they are building a microprocessor, and specifically in the size and efficiency of energy use later. Processors that have been created using the new technology microarchitecture Nehalem is 45 nm in size compared with earlier processors that measured 65 nanometers - a difference which greatly increases the efficiency of energy use, leading to increased performance and power to the computer.
Family Core i7 processors also extends the capabilities of the computer, thanks to use what is known as multi-core processors. Core processors and independent can be integrated to work together in a single computer. Microprocessors that have been created using the Nehalem available in models with four or eight cores. Signals are transmitted through the presence of many cores that are integrated, and between these departments can go much faster. This produces the best signal quality, and allows at a later time to be processed more data faster.
While processing the data in these speeds can greatly increase the ability of the computer for multi-tasking, there are some disadvantages to computing with multiple cores. By working faster and more difficult, can be multi-core processors and put pressure on other areas of the computer, bandwidth and a memory. Also, multi-core technology is only as good as the software, while improvements have been made in the models Core i7, and the only time to know whether the program is able to maximize the potential of many cores.
Core i7 processors are available in computers that are sold by many of the top computer manufacturers, which is available for both laptop and desktop computers. There are seven types of processors for desktop and seven other items of portable computers. Different numbers of processors view the details of work to suit the needs of the user's computer, such as the number of cores, clock speed of the processor, and the ability to cache, the size of nanometers, and the type of technology promotion.
Are best suited with computers Core i7 processors to anyone who wants a computer with a strong performance which can handle a wide variety of tasks at one time. When it launched the first processor, and provided computer experts and technology in general high marks and continue to do so because it represents an advance in treatment. Buzz in the area of technology say that, thanks to new micro-architecture Nehalem, Core i7 processors is not just a technology upgrade or renewal of the former, but it is a completely new design of processors that can provide a completely new set of possibilities

Multi-core processor and integrated circuits that use two or more individual processors, or cores, to handle the data. Can be installed and one of the cores and integrated circuits, or to include in the chapter die in a chip. Each core and cache tags and each has an independent capability for data processing.
Is to increase the use of multi-core processor speed. And traditional stores and one processor core of some data in the cache, and when required data out of the cache, it must be retrieved from other places such as random access memory (RAM). When this happens, the processor speed slows down to a top speed of random access memory or other storage device. This speed is usually much slower than the processor speed limit.
Multi-core processors, and faster because each core can handle the data stream of its own. While multi-core processors and cache data selectively and still retrieve the data is not cached other storage locations could be additional core or cores follow-up to execute commands and receive information at the speed of the physiotherapist, while another processor is to retrieve the required information from storage devices is slow. In this way, the whole system is not necessary to slow down while data is retrieved.
The multi-core processor is particularly valuable for multi-tasking, where more than one program, each serving a group of its own data for processing. In separate data streams can be handled by different cores, and increase the overall processing speed. For a computer program and one to take advantage of multi-core technology, it should be in the same time multi-threaded technology (named), which allows him to send the parallel sets of instructions for the use of multiple cores.
It was the first commercially available multi-core processor in the dual-core processor. There is also a multi-core processors with four, six and eight cores. Many paintings, however, unable to deal with this many cores. Systems can be homogeneous multi-core, using all the samples are identical, or heterogeneous, using the samples do not match.
Although the intended multi-core processors to increase speed and performance, and not all programs to take advantage of multi-core processor technology. Many programs and even some operating systems lack the senior management team need to use more than one processing core. Operating systems that use multi-core processors are not designed to maximize the potential is always multi-core processing, and thus the ability to process a full go in often unrealized.
The multi-core processor tends to produce more heat from a single processor core, causing the management challenges of the heat. The amount of heat produced by the processor tends to rise exponentially with each additional core. High temperatures can cause high temperature treatments for, and create operational problems and safety risks. The processor manufacturers to invest time and technology to find solutions to the challenges presented by the thermal multi-core processors.
