Download

The FermiQCD code is hosted on Google Code using the Mercurial distributed version control system. To install FermiQCD you need to download and install Mercurial then type from the bash shell:

hg clone https://fermiqcd.googlecode.com/hg/ fermiqcd

You can also browse the files online. Once you have downloaded FermiQCD, no installation is required. You just need to compile the examples making sure that the compiler can find the *.h files in the Libraries folder. The FermiQCD code is in this .h files. If you make it this far, feel free to email the author for assistance.
