研究主动布朗运动的OpenCL/OpenGL方法
OpenCL/OpenGL approach for studying active Brownian motion
摘要:
这项工作提出了一种方法,研究主动布朗动力学棘轮电位使用互操作OpenCL和OpenGL框架。随着优化问题的详细说明进行了讨论,然后由COM-在不同设备上的性能。使用OpenGL与OpenCL共享缓冲区的可视化时间已经针对另一种技术进行了测试,该技术在使用OpenGL时不与OpenCL共享内存缓冲区。这两种方法都与将数据可视化到外部软件gnuplot进行了比较。OpenCL/OpenGL互操作方法被认为是最适合于可视化任何大的数据集,计算本身不是很长。
英文摘要:
This work presents a methodology for studying active Brownian dynamics on ratchet potentials using interoperating OpenCL and OpenGL frameworks. Programing details along with optimization issues are discussed, followed by a com- parison of performance on different devices. Time of visualization using OpenGL sharing buffer with OpenCL has been tested against another technique which, while using OpenGL, does not share memory buffer with OpenCL. Both methods have been compared with visualizing data to an external software - gnuplot. OpenCL/OpenGL interoperating method has been found the most appropriate to visualize any large set of data for which calculation itself is not very long.
