This is the gem5 simulator.
The main website can be found at http://www.gem5.org
A good starting point is http://www.gem5.org/about, and for more information about building the simulator and getting started please see http://www.gem5.org/documentation and http://www.gem5.org/documentation/learning_gem5/introduction.
To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, SWIG, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/documentation/general_docs/building for more details concerning the minimum versions of the aforementioned tools.
Once you have all dependencies resolved, type 'scons build//gem5.opt' where ARCH is one of ARM, NULL, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. See http://www.gem5.org/documentation/general_docs/building for more details and options.
The basic source release includes these subdirectories:
- configs: example simulation configuration scripts
- ext: less-common external packages needed to build gem5
- src: source code of the gem5 simulator
- system: source for some optional system software for simulated systems
- tests: regression tests
- util: useful utility programs and files
To run full-system simulations, you will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images.

Enjoy using gem5 and please share your modifications and extensions.
首先，使用如下命令clone该仓库
git clone https://github.com/Raymondwo/gem5-src.git
然后，在stable分支的基础上，创建自己的分支。
git checkout stable
git checkout -b ray-mybranch
修改本地文件，例如readme。
git add readme
git commmit -m "modify the readme file"
上传本地分支到远程。
git push --set-upstream origin ray-mybranch
所有ray创建的分支将使用ray作为开头。首先，大家创建一个自己的master分支，然后在该分支的基础上创建tutorial分支等。
