They instrumented a large set of Java benchmarks to look at the array accesses, over 3 billion of them in total. The majority fell into five simple access patterns. See the pictures on page 8 of the PDF. https://arxiv.org/abs/2403.02416 Regards, John Levine, johnl@taugh.com, Taughannock Networks, Trumansburg NY Please consider the environment before reading this e-mail. https://jl.ly
