Efficiency of Parallel Computing Based on .Net 4.5

Abstract

In recent decades, with the continuous development of the CPU, the speed of single-core processors is increasingly close to the limit. Therefore, multi-core processors, through the internal integration of multi cores, solve the bottleneck in the development of the CPU. Over the past decade, the pace of development of multi-core technology is very fast, but the development of the software has not kept up with the pace of hardware. Most software and program failed to fully utilize the performance of multi-core processors. This paper introduces the parallel programming knowledge of Microsoft .Net 4.5 through the design of an experiment seeking the largest prime number demonstrates parallel the implementation process. Meanwhile, through the comparison of the time consumption between the parallel computation and traditional method, the author draw a conclusion that the computation efficiency is greatly improved by parallel computation then the traditional method in case of large amount of data. © Springer-Verlag Berlin Heidelberg 2013.
