In this paper a survey on current trends in parallel computing has been studied that depicts all the aspects of parallel computing system. A large computational problem that cannot be solved by a single CPU can be divided into a chunk of small enough subtasks which are processed simultaneously by a parallel computer. The parallel computer consists of parallel computing hardware, parallel computing model, and software support for parallel programming. Parallel performance measurement parameters and parallel benchmarks are used to measure the performance of a parallel computing system. The hardware and the software are specially designed for parallel algorithm and programming. This paper explores all the aspects of parallel computing and its usefulness.
