I guess you've got a Quanta server to test against? I sent a quick email to the FreeBSD foundation and Robert Watson = suggested someone from Tilera, Chris?, should come to brief the FreeBSD developer = summit in=20 Ottawa this year and they would like interested students/faculty=20 from CMU to attend as well to give a talk about their work, in = particular, progress, motivations, and obstacles,=20 The developer summit would be held just after or just before BSDCan in = this case, http://www.bsdcan.org/2012/ The Tilera boards appeal to me a way of breaking the x86 stranglehold on servers as they're still so power hungry. I've got a feeling ARM is = going to take a long time to penetrate the server market, but Tilera is = aggressively attacking it. Cheers, Mark=
