本文记录了在Ubuntu系统上进行gem5和nvmain集成，并使用spec cpu2006基准测试的过程。首先解压并安装spec cpu2006，接着修改配置文件以适应gem5的需求。通过运行特定命令编译benchmark，例如gcc。在gem5中执行测试时遇到'Increasing stack size by one page'的问题，虽然能运行但仍有待解决。

最近在研究gem5，nvmain, 并将nvmain集成到gem5里面，然后用基准测试spec cpu2006进行测试。之前一直找不到基准测包，现在终于找到了，在此写下实验过程。

我的系统是ubuntu,spec cpu 2006是cpu2006-1.2.iso镜像。
1. 解压cpu2006-1.2.iso

2 .安装spec cpu 2006

执行下面的命令：

./install.sh -d /home/jyf/download/speccpu2006

注意：/home/jyf/download/speccpu2006 是我电脑上的安装路径，可自定义。

3.运行shrc脚本

source shrc

4.修改配置文件
将config目录下的 Example-linux64-amd64-gcc41.cfg配置文件复制下，命名为gcc41.cfg，由于gem5运行spec需要静态可执行文件，所以将gcc41.cfg文件修改：
将

COPTIMIZE   = -O2  
CXXOPTIMIZE = -O2  
FOPTIMIZE   = -O2

改为

COPTIMIZE   = -O2 -static
CXXOPTIMIZE = -O2 -static
FOPTIMIZE   = -O2 -static

5.编译其中一个benchmark(这里是编译的gcc)
runspec –config=gcc41.cfg –action=build –tune=base gcc

若出现runspec找不到命令时，需要回退到spec的安装目录，即输入命令

.空格./shrc

注意：编译成功后会在bencuspec下的cpu2006下的403.gcc包里产生exe和build两个文件。

6.在gem5中用cpu 2006进行基准测试：

./build/X86/gem5.opt ./configs/example/se.py -c ../../speccpu2006/benchspec/CPU2006/450.soplex/exe/soplex_base.gcc41-64bit -o ../../speccpu2006/benchspec/CPU2006/450.soplex/data/test/input/test.mps

注意：
540.sople可以运行，运行结果在/home/jyf/download/gem_nvmain/gem5-master/m5out/stats.txt，但还是会提示：info: Increasing stack size by one page.
运行结果：
