Super computer

Supercomputer is a computer world leader in processing capacity, particularly speed of calculation, at the beginning of his introduction. Supercomputers introduced in the 1960s, designed by Seymour Cray at Control Data Corporation (CDC), led the market in the 1970s until Cray quit to form his own corporation, Cray Research .

He then took the supercomputer market with its design, the whole supercomputer leader for 25 years (1965-1990). In the 1980s several small competitors entering the market, which together with the creation of mini-computers in the previous decade. now, the supercomputer market is held by IBM and HP , although Cray Inc.. still specialize in the manufacture of supercomputers.

PlayStation 3

PlayStation 3 (Japanese language: ?????????3, San Pureisut?shon, trademark: PLAYSTATION 3, abbreviated PS3) is the console Sony third generation. PlayStation 3 is the successor to the PlayStation and PlayStation 2 and will compete with the Xbox 360 from Microsoft and the Wii from Nintendo.

PlayStation 3 released in Japan on 11 November 2006 promptly at seven, and will be released on November 17, 2006 in North America (United States and Canada), Hong Kong and Taiwan, and 1 or March 7, 2007 in Europe and Australia, and the region Other PAL. PlayStation 3 will be released with 2 types, Basix and Premium / Platinum. PlayStation 3 officially introduced to the world on May 16, 2005 at E3. The first final configuration is shown in the TGS (Tokyo Game Show) 2006.

Latest technology used is its cell processor, processor type that really optimized to perform floating point operations. Unlike with desktop processors in general, the ability of the PS3 cell processor to perform floating point operations very well. Cell processor’s ability to perform floating point operations is very good because the cell processor is a vector processor architecture. Even processors that are used in the PS3 is the most advanced processors today. Also GPU itself is made in cooperation with NVidia.

Graphics cards can also be overclocked ( computer )

Graphics cards

Graphics cards can also be overclocked, with utilities such as EVGA’s Precision, RivaTuner, ATI Overdrive (on ATI cards only), MSI Afterburner, or the PEG Link Mode on ASUS motherboards. Overclocking a GPU will often yield a marked increase in performance in synthetic benchmarks, and usually will improve game performance too. Sometimes, it is possible to see that a graphics card is pushed beyond its limits before any permanent damage is done by observing on-screen distortions known as artifacts. Two such discriminated “warning bells” are widely understood: green-flashing, random triangles appearing on the screen usually correspond to overheating problems on the GPU itself, while white, flashing dots appearing randomly (usually in groups) on the screen often mean that the card’s RAM is overheating. It is common to run into one of those problems when overclocking graphics cards. Showing both symptoms at the same time usually means that the card is severely pushed beyond its heat/clock rate/voltage limits. If seen at normal clock rate, voltage and temperature, they may indicate faults with the card itself. However, if the video card is simply clocked too high and doesen’t overheat then the artifacts are a bit different. There are many different ways for this to show up and any irregularities should be considered but usually if the core is pushed too hard black circles or blobs appear on the screen and overclocking the video memory beyond its limits usually results in the application or the entire operating system crashing. Luckily though, after the computer is restarted the settings is reset to stock (Stored in the video card BIOS) and the maximum clock rate of that specific card has been found.

Some overclockers use a hardware voltage modification where a potentiometer is applied to the video card to manually adjust the voltage. This results in much greater flexibility, as overclocking software for graphics cards is rarely able to freely adjust the voltage. Voltage mods are very risky and may result in a dead video card, especially if the voltage modification (“voltmod”) is applied by an inexperienced individual. A pencil volt mod refers to changing a resistor’s value on the graphics card by drawing across it with a graphite pencil. This results in a change of GPU voltage. It is also worth mentioning that adding physical elements to the video card immediately voids the warranty.

Alternatives

Flashing and Unlocking are two popular ways to gain performance out of a video card, without technically overclocking.
Flashing refers to using the firmware of another card, based on the same core and design specs, to “override” the original firmware, Read more…

Sustainable energy , Energy efficiency , Green energy

Sustainable energy is the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their needs. A broader interpretation may allow inclusion of fossil fuels as transitional sources while technology develops, as long as new sources are developed for future generations to use. A narrower interpretation includes only energy sources which are not expected to be depleted in a time frame relevant to the human race, which can potentially also include nuclear power if it is utilized differently from the current manner.

Sustainable energy sources are most often regarded as including all renewable sources, such as biofuels, solar power, wind power, wave power, geothermal power and tidal power. It usually also includes technologies that improve energy efficiency. Conventional fission power is sometimes referred to as sustainable, but this is controversial politically due to concerns about peak uranium, radioactive waste disposal and the risks of disaster due to accident, terrorism, or natural disaster.

Energy efficiency

Moving towards energy sustainability will require changes not only in the way energy is supplied, but in the way it is used, and reducing the amount of energy required to deliver various goods or services is essential. Opportunities for improvement on the demand side of the energy equation are as rich and diverse as those on the supply side, and often offer significant economic benefits.

Renewable energy and energy efficiency are Read more…

Green computing or green IT , Roads to Green Computing

Green computing or green IT, refers to environmentally sustainable computing or IT. It is “the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment. Green IT also strives to achieve economic viability and improved system performance and use, while abiding by our social and ethical responsibilities. Thus, green IT includes the dimensions of environmental sustainability, the economics of energy efficiency, and the total cost of ownership, which includes the cost of disposal and recycling. It is the study and practice of using computing resources efficiently.”

With increasing recognition that man-made greenhouse gas emissions are a major contributing factor to global warming, enterprises, governments, and society at large now have an important new agenda: tackling environmental issues and adopting environmentally sound practices. Greening our IT products, applications, services, and practices is both an economic and an environmental imperative, as well as our social responsibility. Therefore, a growing number of IT vendors and users are moving toward green IT and thereby assisting in building a green society and economy.

The goals of green computing are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product’s lifetime, and promote recyclability or biodegradability of defunct products and factory waste.
