Paul Elschot commented on LUCENE-1410: -------------------------------------- Q: I'm using fixed 6-bit frame size. Can you add bigger bit sizes to your pfor decompress? A: It should work for 1<=numFrameBits<=30. That answer was too short. There is some fallback code (decodeAnyFrame) that will decompress for any frame or reference. The patch contains unrolled versions of that for up to 7 bits iirc. I'll add higher numbers of bits later, the code is straightforward and it could actually be generated. Btw. on my machine the unrolled 9 bit version is actually a bit slower than the loop, I don't know why, maybe there are too many buffer references (9) in the loop for the jit to cope with. > PFOR implementation > ------------------- > > Key: LUCENE-1410 > URL: https://issues.apache.org/jira/browse/LUCENE-1410 > Project: Lucene - Java > Issue Type: New Feature > Components: Other > Reporter: Paul Elschot > Priority: Minor > Attachments: LUCENE-1410b.patch, TestPFor2.java > > Original Estimate: 21840h > Remaining Estimate: 21840h > > Implementation of Patched Frame of Reference. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
