Yibo Cai created ARROW-18162: -------------------------------- Summary: [C++] Add Arm SVE compiler options Key: ARROW-18162 URL: https://issues.apache.org/jira/browse/ARROW-18162 Project: Apache Arrow Issue Type: Improvement Components: C++ Reporter: Yibo Cai Assignee: Yibo Cai
{{xsimd}} 9.0+ supports Arm SVE (fixed size). Some additional compiler options are required to enable SVE. Per my test on Amazon Graviton3 (SVE-256). SVE256 performs much better than NEON for some cases. E.g., utf8 benchmark {{ValidateLargeAscii}} improves from *38.6* (NEON) to *51.5* (SVE256) GB/s. -- This message was sent by Atlassian Jira (v8.20.10#820010)
