最近在看gem5源码时,对gpu的核心源码很感兴趣。结合amd在isca18的发表,学习一下gpu core的架构。 GPU CORE 微架构 GPU ISA的op type 从这个表可以看出,GPU ISA里使用vector命令来指会wavefront。在GPU中,Wavefront是执行的基本单位,通常由64个线程组成。这些线程在同一个Wavefront中执行相
gem5-gpu 选项解释 ‘--split’ ,该项用于模拟独立显卡,GPU与CPU不在同一芯片上,两者的内存物理上隔绝,使用PCI-Express连接。 ‘--access-host-pagetable’,该项用于模拟集成显卡,GPU与CPU在同一芯片上,共享物理内存,(1)当运行正常的Rodinia程序时,依然需要通过DMA引擎把数据从CPU空间复制到GPU空间,大多数协议保证...

首先庆祝一下终于成功搭建好了gem5-gpu实验环境,再次感谢实验室的小伙伴们(虽然他们可能看不到哈哈哈) 这里主要有几个点需要注意: 搭建gem5-gpu必须要使用CUDA,而且还必须使用那种非常老的CUDA 3.2,所以一定一定在ubuntu14.04上搭建,别的系统版本会涉及系统内核的问题造成搭建失败……另外装nvidia驱动是一个非常麻烦的...
