At TransGaming‚ we believe that this convergence will continue to the point where typical systems have only one type of processing unit‚ with large numbers of cores and very wide vector execution units available for high performance parallel execution. In this kind of environment‚ all graphics processing will ultimately take place in software. Through our SwiftShader software GPU toolkit‚ TransGaming has long been a world leader in software based rendering‚ with widespread adoption of

systems using FPGAs and FPGA use models are described. I. Introduction Due to high application demand conventional processors are unable to deliver desired performance. So hardware acceleration is required to meet high performance. This is done by parallel computing and by connecting application specification processors. Because of low price‚ low power consumption and high performance FPGAs are used in the basic coprocessor design. Until 2000‚ single core CPU based systems are used for High Performance

A scientist studying proteins logs into a computer and uses an entire network of computers to analyze data. A businessman accesses his company’s network through a PDA in order to forecast the future of a particular stock. An Army official accesses and coordinates computer resources on three different military networks to formulate a battle strategy. All of these scenarios have one thing in common: They rely on a concept called grid computing. Clusters And Grid A computer cluster is a group of

Attempt to produce man-made fibre was first started with Artificial Silk’ at 1855 in England by Swiss chemist named Audemars. The fibrous inner bark of mulberry tree was then chemically modified to produce cellulose. At 1880s‚ sir Joseph Swan an English chemist experimented by forcing the cellulose liquid through fine holes into a coagulating bath. First commercial production of artificial fibre was achieved by French chemist Count Hilaire de chardonnet at 1889 in France. At that time he produced

Lyocell Lyocell is a newly manufactured cellulose fibre which is used in a wide range of clothing and household textiles due to its very unique properties. These properties include: strong‚ long lasting‚ variety of textures (including silky and denim feel)‚ absorbent and wicks moisture. In addition it is very durable‚ so it can be used in conveyor belts‚ oil filters‚ and capacitor separators. Lyocell is made by dissolving wood pulp into amine oxide solvent which changes chemical and surface properties
