This paper presents two coupled software packages which receive widespread use in the ﬁeld of numerical simulations of Quantum Chromo-Dynamics. These consist of the BAGEL library and the BAGEL Fermion sparse-matrix library, BFM. The Bagel library can generate assembly code for a number of architectures and is conﬁgurable – supporting several precision and memory pattern options to allow architecture speciﬁg optimisation. It provides high performance on the QCDOC, BlueGene/L and BlueGene/P parallel computer architectures that are popular in the the ﬁeld of lattice QCD. The code includes a complete conjugate gradient implementation for the Wilson and Domain Wall fermion actions, making it easy to use for third party codes including the Jefferson Laboratory’s CHROMA, UKQCD’s UKhadron, and the Riken-Brookhaven-Columbia collaboration’s CPS packages.
