Subject [jira] [Commented] (ARROW-90) Apache Arrow cpp code does not support power architecture
Date Tue, 29 Mar 2016 12:37:25 GMT

    [ https://issues.apache.org/jira/browse/ARROW-90?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15215942#comment-15215942

Kai Zheng commented on ARROW-90:
--------------------------------

bq. To enable SIMD support(SIMD being feature of best processor) for power architecture for
Apache Arrow, needs to replace "sse3" with "altivec" flag in "CMakeLists.txt".
I understand it needs to support power arch, but why it has to replace "sse3" with "altivec"?
IMO, this should be done intelligently, switching to the other by detecting the underlying
CPU arch, please.
