Greg Miller commented on LUCENE-9918: ------------------------------------- I've setup a microbenchmark project over [here|https://github.com/gsmiller/lucene-pfor-benchmark] to help explore this more easily if anyone is interested. I'll probably mess around with this a bit, but don't let that stop you from working on it if interested :) > Can PForUtil be further auto-vectorized? > ---------------------------------------- > > Key: LUCENE-9918 > URL: https://issues.apache.org/jira/browse/LUCENE-9918 > Project: Lucene - Core > Issue Type: Task > Components: core/codecs > Affects Versions: main (9.0) > Reporter: Greg Miller > Priority: Minor > > While working on LUCENE-9850, we discovered the loop in PForUtil::prefixSumOf > is not getting auto-vectorized by the HotSpot compiler. We tried a few > different tweaks to see if we could change this, but came up empty. There are > some additional suggestions in the related > [PR|https://github.com/apache/lucene/pull/69#discussion_r608412309] that > could still be experimented with, and it may be worth doing so to see if > further improvements could be squeezed out. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
