摘要:

曙光E级原型机是我国“十三五”计划中3台原型系统之一,该系统采用异构计算架构,CPU和加速器选用AMD授权的国产海光处理器架构。除了采用基准测试程序对芯片进行测试外,为探究真实应用在该原型机上的性能,移植了激光等离子体应用GTC-P,对比了GTC-P在海光CPU和DCU与Intel 6148 CPU和NVIDIA V100 GPU上的性能,并在原型机的多结点上进行了扩展性分析。性能评估工作反映了高性能计算应用在曙光E级原型机上的实际运行性能。

Abstract:

As one of three exascale prototypes for the 13th Five-Year Plan, Sugon exascale prototype uses heterogeneous computing architecture. In the prototype, CPUs are the domestically-produced Hygon x86 processors authorized by AMD, and accelerators are Hygon DCUs (Deep Computing Units). In addition to testing the chips with benchmarks, in order to study the performance of real applications on this prototype, we port a Particle-In-Cell application called Gyrokinetic Toroidal Code at Princeton (GTC-P). We compare the performance and scalability of GTC-P on Hygon CPU and DCU with Intel 6148 CPU and NVIDIA V100 GPU. Our evaluation show the performance of real HPC application on Sugon exascale prototype.
