**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)
** Short and long-term GC plan discussion. MMGC within SpiderMonkey. Can we use for MMGC or put lightweight internal API to avoid forking?  Make sure focus is on Tamarin Tracing vs. Tamarin Central
** Jungwoo completed code alignment of trace prologues, loop headers, and trace epilogues. No significant performance gains observed yet.
*** Steven though short-term GC needs OK for Adobe.  But, Tom has an API that extracts over MMGC and SPAM (for smaller devices). Tom to get involved with this (Brendan to assist w/ getting Tom involved). It would be ideal to get Lars involved on GC as well, but that will have to wait for now.
*** Rick (Adobe) wants to review some of this, so he will check in with Moh this. Rick needs to try this on SunSpider.  
** Has Jason Evans started his integration yet?  Not fully, so good time to review API vs. forking, etc.
*** 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.  
*** Ben to start thread on tamarin-devel list on this.
**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 also wants to merge MMGC with Tamarin Tracing
 
* Steven (Adobe)
** Has been tied up with internal work, so no major updates.  But, Adobe has new Tamarin employee: Vladamir!


* Rick (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.
** Posted a patch for trace trees this past week, but is still a bit buggy.


* Brendan (Mozilla)
* Next week:
** 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.
**Need to discuss ScreamingMonkey w/ Jeff H.
** Performance of ESC and Tamarin Central is next major project. Brent Baker has been helping with QE- he may be able to assist.
