  Recently, we have benchmarked and tuned the MILC code on a number of
architectures including Intel Itanium and Pentium IV (PIV), dual-CPU Athlon,
and the latest Compaq Alpha nodes. Results will be presented for many of these,
and we shall discuss some simple code changes that can result in a very
dramatic speedup of the KS conjugate gradient on processors with more advanced
memory systems such as PIV, IBM SP and Alpha.
