![]() ![]() 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. Contact me for payment methods to pay on pickup.IBM's Blue Gene/P massively parallel supercomputer Photos may include items that are not for sale. Grills have been replaced with green cloth and nameplates have been removed. Warranty and information cards have been removed, some serial numbers are unknown. Currently the four speakers are driven by a Kenwood Basic M1 (105w per channel claimed), but I have used a 50w per channel Sansui amp with no problems.Size: approx. To do this the two 8 ohm speakers on each side must be connected in parallel, so you need a power amp capable of driving a 4 ohm load per channel. Why four speakers? To build the legendary “double advent” or “stacked” configuration with the top two units inverted so that the tweeters are close together, creating a dispersion pattern that exceeds the capability of two speakers alone, and an overall great sound. Woofers have been refoamed once or twice, dates unknown at present they appear to be in good condition. I have replaced crossover capacitors on two of them. They feature 10” woofers for low end, and switchable crossovers to fine tune the highs. They were produced between 19 to universal acclaim. For sale, four of the original Larger Advent speakers. ![]()
