Graphic process units (GPUs) are widely used in scientific computing, because of their high performance and energy efficiency. Nonetheless, GPUs are featured with a hierarchical memory system, on which code optimization requires an in-depth understanding for programmers. For this, we often measure the capability (latency or bandwidth) of the memory system with micro-benchmarks. Prior works focus on...
Fast independent component analysis (Fast ICA) for hyper spectral image dimensionality reduction is computationally complex and time-consuming due to the high dimensionality of hyper spectral images. By analyzing the Fast ICA algorithm, we design parallel schemes for covariance matrix calculating, white processing and ICA iteration at three parallel levels: multicores, many integrated cores (MIC),...
The space computer puts forward high demands on the performance. Therefore, the high-performance digital signal processors are increasingly used in the space computer. However, the single particle effects caused by the cosmic radiation make the reliability of the space computer become a huge challenge. The COTS DSP chip has a huge advantage compared to the antiradiation DSP chip in performance, price,...
