An Overview on High Performance Issues of Parallel Architectures
Koushik Chatterjee, Sumit Joshi · Internet Technologies and Applications Research · 2013
In recent years, as microprocessors have become cheaper and the technology for interconnecting them has improved, it has become both possible and practical to build general-purpose parallel computers containing a very large number of processors. Processors in a parallel computer need to communicate in order to solve a problem. Therefore, there is a need for some kind of communication highway or interconnection network, i.e. the processors to be connected in some pattern. Performance in multiprocessor systems is highly dependent on communication processes between processors and memory, I/O devices, and other processors. Therefore, choosing the right interconnection network is important for efficiency reasons. In the present work the issues of High Performance in parallel computing to achieve parallel architecture at level of hardware and software has been studied.
