![]() Parallel computers can be roughly classified according to the level at which the hardware supports parallelism, with multi-core and multi-processor computers having multiple processing elements within a single machine, while clusters, MPPs, and grids use multiple computers to work on the same task. In contrast, in concurrent computing, the various processes often do not address related tasks when they do, as is typical in distributed computing, the separate tasks may have a varied nature and often require some inter-process communication during execution. In parallel computing, a computational task is typically broken down into several, often many, very similar sub-tasks that can be processed independently and whose results are combined afterwards, upon completion. ![]() Parallel computing is closely related to concurrent computing-they are frequently used together, and often conflated, though the two are distinct: it is possible to have parallelism without concurrency, and concurrency without parallelism (such as multitasking by time-sharing on a single-core CPU). As power consumption (and consequently heat generation) by computers has become a concern in recent years, parallel computing has become the dominant paradigm in computer architecture, mainly in the form of multi-core processors. Parallelism has long been employed in high-performance computing, but has gained broader interest due to the physical constraints preventing frequency scaling. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism. Large problems can often be divided into smaller ones, which can then be solved at the same time. Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously. I welcome local customers - here are directions and a map.IBM's Blue Gene/P massively parallel supercomputer I also perform a wide range of expert speaker repairs - I can fix virtually any repairable brand or type of speaker. I offer intensive specialized service and support for speakers from the 1970s and 80s made by Genesis Physics Corporation and EPI - Epicure Products Incorporated. speaker builder - build your own speakers with HUMAN parts and kits. I also provide a range of high quality parts and kits for the D.I.Y. ![]() The HUMAN Model 81 was rated 9/10 ("nearly flawless, buy it now") by Wired magazine. I build a line of new speakers by hand here in New Hampshire, USA, and ship them worldwide. ![]() The long-awaited HUMAN 81 DK is now available. ![]()
