Benchmarking and tuning the MILC code on clusters and supercomputers

摘要

Recently, we have benchmarked and tuned the MILC code on a number ofarchitectures 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.
