模拟生物分子的相互作用,或对接,对于理解基本的生命过程和设计新药都至关重要。描述了基于现场可编程门阵列(FPGA)的最近开发的、复杂的、生产对接代码的加速。作者发现,有必要以多种方式扩展他们以前的三维(3D)相关结构,最重要的是支持同时计算几个相关函数。小分子对接的结果是一段代码的速度提高了100倍,这段代码代表了原始运行时间的95%以上。另外2%的加速是通过前面描述的方法进行的,单核的总加速为36倍,四核的总加速为10倍。这种方法被认为是一个理想的补充图形处理单元(GPU)的基础上的对接,它擅长在蛋白质-蛋白质域。
Modelling the interactions of biological molecules, or docking, is critical both to understanding basic life processes and to designing new drugs. The field programmable gate array (FPGA) based acceleration of a recently developed, complex, production docking code is described. The authors found that it is necessary to extend their previous three-dimensional (3D) correlation structure in several ways, most significantly to support simultaneous computation of several correlation functions. The result for small-molecule docking is a 100-fold speed-up of a section of the code that represents over 95% of the original run-time. An additional 2% is accelerated through a previously described method, yielding a total acceleration of 36× over a single core and 10× over a quad-core. This approach is found to be an ideal complement to graphics processing unit (GPU) based docking, which excels in the protein–protein domain.
