Revision as of 21:31, 3 June 2008
- These updates concern Tamarin and related projects only.
Meeting Details
- 2:00pm Pacific Time (21:00 UTC) on Tuesdays
- (5PM Eastern US, 11PM Oslo, 6AM (Wed) Seoul, 7AM (Wed) Melbourne)
- Location: Tel: 866 705 2554 (us), 913 227 1201 (int’l)
- Passcode: 9140087
- Duration: 60 minutes
- join irc.mozilla.org #tamarin for attendence taking and questions
- Next meeting's Agenda Items:
- (Moh/Intel)-
- Shengnan has got the VTune sampling support for TT in place. The first version runs all Sunspider tests without any known problems. We're waiting for feedback from Rick & Ed. bug 436987.
- Jungwoo completed code alignment of trace prologues, loop headers, and trace epilogues. No significant performance gains observed yet.
- (Moh/Intel)-
- Last meeting's Agenda Items:
- (Moh/Intel)-
- Significant performance improvements through a shortcut in String::equalsUTF8
- runtests.py script is unfair
- Does it make sense to have a fast post-codegen pass to do code-alignment among other peephole optimizations? Starting points? Jungwoo is exploring.
- Shengnan needs LIR_file and LIR_line in TT to enable VTune. Starting points?
- (Jim/Mozilla)-
- Moving TC's MMgc into TT: compiles, but there are still test regressions. Tommy has reviewed changes from TT's MMgc for inclusion in TC's MMgc (backmerge); seven patches waiting for review
- (Moh/Intel)-
3rd June 2008

Updates
- Moh (Intel)-
- Shengnan has got the VTune sampling support for TT in place. The first version runs all Sunspider tests without any known problems. We're waiting for feedback from Rick & Ed. (bug# 436987)
- Jungwoo completed code alignment of trace prologues, loop headers, and trace epilogues. No significant performance gains observed yet.
- Rick (Adobe) wants to review some of this, so he will check in with Moh this. Rick needs to try this on SunSpider.
- We need a new filename for the trace/fragment. VTune requires continuous code for each trace. Moh wants to link name with the line number so that it stays constant.
- Hot exit thresholds- there are a few different numbers, Jungwoo has been having luck from increasing the number from 2 to 10 (on SunSpider). Moh and team will continue to explore this.
- Moh (Intel)-
- Steven (Adobe)
- Has been tied up with internal work, so no major updates. But, Adobe has new Tamarin employee: Vladamir!
- Steven (Adobe)
- Rick (Adobe)
- Continuing to work on trace trees. Currently, can run some of the benchmarks with trace trees. Some have broken, so is currently debugging but hopes to get all the benchmarks running soon.
- Rick (Adobe)
- Brendan (Mozilla)
- Wants to see that Mark Hammond gets the help he needs for Screaming Monkey. Jeff says that there are some solutions out there (in Lars, Jeff, and others heads). Jeff to ping Brendan with the bug number (#417342). There is a dupe bug that has even more detail.
- Performance of ESC and Tamarin Central is next major project. Brent Baker has been helping with QE- he may be able to assist.
