Fermiqcd: a Tool Kit for Parallel Lattice Qcd Applications

FermiQCD is a collection of classes, functions and parallel algorithms for lattice QCD [1], written in C++. It is based on Matrix Distributed Processing (MDP) [2]. The latter is a library that includes C++ methods for matrix manipulation, advanced statistical analysis (such as Jackknife and Boostrap) and optimized algorithms for interprocess communications of distributed lattices and fields. These communications are implemented using Message Passing Interface (MPI) but MPI calls are hidden to the high level algorithms that constitute FermiQCD. FermiQCD works also on single processor computers and, in this case, MPI is not required.
