Hello Lili Cui,
Since I'm also trying to improve this lately, I've tested your patch on
several aarch64 machines we have, including neoverse-n1 and ampere1
architectures. However, I haven't reproduced the 6.00% improvement of
503.bwaves_r single copy run you mentioned. Could you share more inform
I will rebase and commit this patch, thanks!
Lili.
