Hi As an avid game as well as AI programmer, (and long time lurker on this list) I was wondering if anyone had given any thought running their code on a DX11 graphics card with openCompute enabled?
I have read about some colleagues running market simulations on them due to their exceptionally high multithreading and fast memory, but I wondered if there was some obvious limitation that I had overlooked before I start working in this direction and learning a while new low level API.

I wrote about my experiences with testing of Pachi on computers at our university department just a few months ago. Our top-performance stations are i7 920 with hyperthreading (i.e. 8-threaded; one year old), and Phenom 1090T machines (6-threaded; bought this Christmas). We currently do not overclock either, and my experience is that total performance sum over all threads is the same for i7 920 and AMD 1090T. You could milk quite a bit more from current i7, but Phenoms are cheaper (and you rightfully notice also the much cheaper MoBos). > 5.

We also have a server with two 8-thread Opterons 6134, the per-thread speed is just a bit faster than hyperthreaded i7 920 per-thread speed. (I.e. it is roughly like two i7-920 with shared memory.) It was not too expensive, but server-grade Opterons and Xeons are ridiculously overpriced. My personal opinion is that unless shared memory is total must (e.g. for as powerful as possible single instance of program running), you are quite better off with building small cluster of uniprocessor machines. And there, when optimizing solely for smallest purchase price, I think cluster of Phenoms is most cost-effective. Of course, this does not factor in capacity of server room, heat production, power consumption etc. So the important factor is if you are interested just in performance tuning with many single-threaded instances, or want to also run a beefy program doing all simulations on a shared tree. -- Petr "Pasky" Baudis UNIX is user friendly, it's just picky about who its friends are. ------------------------------ Message: 2 Date: Sun, 22 May 2011 09:11:54 +0200 From: Petr Baudis <[email protected]> To: [email protected] Subject: [Computer-go] kgsGtp update required! Message-ID: <[email protected]> Content-Type: text/plain; charset=us-ascii Hi! Beware especially for participants of today tournament - kgsGtp update is required because of nonbackwardscompatible KGS version change tonight: http://files.gokgs.com/changeLog.txt With old kgsGtp, you will see immediate disconnects from server with no further explanation. You can get new kgsGtp version at http://files.gokgs.com/javaBin/kgsGtp-3.5.0.tar.gz http://files.gokgs.com/javaBin/kgsGtp-3.5.0.zip If like me, you have not updated kgsGtp for a while, you might be interested to know that it now supports mode=both to enable both automatch and challenge wait, you can prevent handicap automatch games if you do not support the handicap command, and you can get information about current ruleset used by the kgs-rules command. -- Petr "Pasky" Baudis UNIX is user friendly, it's just picky about who its friends are. ------------------------------ Message: 3 Date: Sun, 22 May 2011 11:05:11 +0200 From: ds <[email protected]> To: [email protected] Cc: [email protected] Subject: Re: [Computer-go] kgsGtp update required!

I updated yesterday, and on the page was 3.4.15 :-) One short question: In http://www.weddslist.com/kgs/how/tourney.html you mention open=f but it is not in the sample file for tournament. Is it recommanded?
