Embodiment Construction
[0067] The present invention is implemented by means of automatic operation. The embodiment uses the extended C language provided by the CUDA architecture as a development tool.
[0068] The CUDA architecture is shown as figure 1 As shown, the embodiments are implemented and run using a high performance PC and a new generation of GPU coprocessors based on the Kepler architecture. In the CUDA architecture, the CPU of a high-performance PC works with the GPU, and the CPU is responsible for logical transaction processing and serial calculations, including data preparation and device initialization before starting the CUDA parallel processing process, and parallel processing in each CUDA. Serial computing is performed between processes, while GPU focuses on executing highly threaded parallel processing tasks. The CUDA parallel processing process running on GPU is called kernel (kernel processing process). A kernel has two levels of parallelism, namely Grid ( Inter-block (thread ...
