Open64 is an open source compiler with powerful analysis and widely used as a research and commercial development platform. However, it has not been designed and developed to realize MPI parallelization. There are many contributions in the paper. Firstly, the Open64 compiler infrastructure is showed. Secondly, the location of MPI code generation in the Open64 compiler architecture is analyzed. Thirdly,...
In this paper, instruction level optimization by exploiting SSE2 instructions is proposed to speed up the time-critical modules in H.264 encoder. SSE2 instruction set to execute a large number of small-size native data type operations in parallel to improve the real-time multimedia data processing capability. The contributions of the paper are manifold: Firstly, the paper shows SSE2 instruction set...
