Abstract

The entire world of parallel computing endured a change when accelerators are gradually embraced in today's high-performance computing cluster. A hybrid CPU-GPU cluster is required to speed up the complex computations by using parallel programming paradigms. This paper deals with performance evaluation of sequential, parallel and hybrid programming paradigms on the hybrid CPU-GPU cluster using the sorting strategies such as quick sort, heap sort and merge sort. In this research work performance comparison of C, MPI, and hybrid [MPI+CUDA] on CPU-GPUs hybrid systems are performed by using the sorting strategies. From the analysis it is observed that, the performance of parallel programming paradigm MPI is better when compared against sequential programming model. Also, research work evaluates the performance of CUDA on GPUs and hybrid programming model [MPI+CUDA] on CPU+GPU cluster using merge sort strategies and noticed that hybrid programming model [MPI+CUDA] has better performance against traditional approach and parallel programming paradigms MPI and CUDA When the overall performance of all three programming paradigms are compared, MPI+CUDA based on CPU+GPU environment gives the best speedup.
