GitHub user chiranmoyFujitsu added a comment to the discussion: Prospects of 
SVE based optimizations

Not just Fujitsu A64X, the 
[Graviton](https://github.com/aws/aws-graviton-getting-started?tab=readme-ov-file)
 series from AWS also supports SVE.

Thank you for the information about the CI. For now, we will try to look into 
possible optimisations with SVE, and the community can make a decision based on 
the utility
