What is the fastest you can make this execute? You might find the output of -ftree-vectorize -fopt-info-vec-missed
(with recent gcc) interesting. Does vectorization matter in this case? Can you trust what the compiler is saying?
Hi Jed,
I think there are two ways to improve the performance of the code. (1) Change G-S to Jacobi. (2) Continue chaining Jacobi to a block version.
