在GPU上使用交错费米子进行QCD模拟

QCD simulations with staggered fermions on GPUs

Claudio Bonati, Guido Cossu, Massimo D'Elia, Pietro Incardona

摘要:

我们报告我们的RHMC算法的模拟格点量子色动力学与两个交错的口味上的图形处理单元的实现,使用NVIDIA CUDA编程语言。我们的代码的主要特点是,GPU不只是作为一个加速器使用,而是整个分子动力学的轨迹上执行。在指出主要的瓶颈和如何规避它们之后,我们讨论了所获得的性能。我们提出了一些关于OpenCL和多GPU扩展我们的代码的初步结果,并讨论未来的前景。

英文摘要:

We report on our implementation of the RHMC algorithm for the simulation of lattice QCD with two staggered flavors on Graphics Processing Units, using the NVIDIA CUDA programming language. The main feature of our code is that the GPU is not used just as an accelerator, but instead the whole Molecular Dynamics trajectory is performed on it. After pointing out the main bottlenecks and how to circumvent them, we discuss the obtained performances. We present some preliminary results regarding OpenCL and multiGPU extensions of our code and discuss future perspectives.
