Grassmann.jl is the library that made me take Julia seriously. It's an awesome library, and the author really gets one of Julia's most special and well integrated features, multiple dispatch. Because the code is written in solid, idiomatic Julia, it's interoperable with tons of other libraries. I actually had success using this library with CuArrays.jl without any modifications. So yeah, you can use it to run geometric algebra computations on a GPU for algebras of dimension < 2^5 (in my case, I tried it with CGA3D).
