He can put it on the agenda and Trevor can give input to the chapter 13:36:01 #info Trevor said there is another aspect of benchmarks 13:38:27 #info Sunku Ranganath 13:41:34 #info Mark said he really liked Trevor's slides. He suggested to discuss it in more details on Wednesday's CNTT call. 13:42:40 #info Mike Fix and Mark S asked for a copy of slides 13:44:09 #info Mike thinks it is very good, and he would like to incorporate some into Chapter 8 13:44:31 #info Trevor will email Bin the slides, and put into minutes on wiki 13:45:50 #info George Yang asked that on page 7 and page 6, if specified in Intel CPU, it may not be applicable to ARM 13:46:42 #info Trevor clarified that it is really up to manufacturer to decide what they think to meet the profile. 13:47:17 #info The spec will not say what to buy to meet the profile. Spec is just a guidance 13:52:54 #topic AOB 13:53:17 #info Trevor will share slides with Bin, and Bin will put it into minutes on wiki 13:53:57 #info Mark will put it into CNTT agenda, and Trevor will present it in CNTT meeting. Important is to have enough time for Trevor to go over the details of proposal 13:54:08 #info Meeting adjourned 13:54:12 #endmeeting
