Portable assembler and other oxymorons

Lattice QCD simulations are computationally intensive, and require multiple teraflop-years of effort to solve. In this context it is imperative to extract the best possible performance from a processor.

We have written a portable code generator for high performance assembler kernels required by Lattice QCD simulations for a number of risc architectures. This results in a significant performance improvement over current optimising compilers.
