摘要：This paper presents Heterogeneous Parallel Computing (HPC), which is a well-orchestrated and co-ordinated effective use of a suite of diverse high performance machines to provide super-speed processing for computationally demanding tasks with diverse computational needs. GPUs are accoutered with a much more throughput oriented design as compared to that of the CPUs thus making them a powerful alternative to boast overall performance. It is now used all the way from mobile computing to supercomputing, like in Blue Star Super Computers. Upcoming Exascale and Petascale systems have embraced even heterogeneity in order to overcome power limitations. This paper also illustrates programming example using CUDA C to demonstrate the efficiency achieved in problems like matrix multiplication using a more heterogeneous approach as compared to that of sequential approach. It also explains how Heterogeneous Parallel Programming is a plausible, novel technique which allows to exploit inherent capabilities of a wide range of computational machines to solve computationally intensive problems that have several types of embedded parallelism by breaking it into separate modules. This paper also puts light on the challenges and concerns which exist when programming in HPC environment and some techniques to alleviate them.
