Don't forget the cost of testing. For perhaps 5 hours of tournament play, I do hundreds of hours of testing before it. Much of that testing must be on the target machine environment.

I'm very confident Pachi can be built for it with minimal headaches. Oliver, the per-hour cost for the "High-CPU Instances" that I would consider the most reasonable for such an event cost $0.68/hour for Linux images and $1.16/hour for Windows images. Machines can be spun up for single hours at a time, there's no "minimum reservation", so the entire event could be run at about the cost of $20 per person. And that's aside from the fact that I feel we have a chance to get a discount or donation from AWS if we go with them. David, Windows Server 2008 is one of the default supported instance types for AWS (details here: http://aws.amazon.com/windows/). The prices are slightly higher (about $0.50 more per hour) to offset the cost of the Windows licenses, but it's still very much within reason. So you can absolutely run Many Faces without the need to put your source code onto the cloud. That is, of course, one of the first things I considered :) Cheers, Adrian On Wed, Sep 29, 2010 at 4:44 PM, David Fotland <[email protected]> wrote: For a big SMP or cluster, the program is tuned somewhat for the environment. If the OS is unusual it might be necessary to compile the program specifically for that machine. Both of these are large barriers to entry. I won't put my source code into the cloud to be compiled there. My engine only runs on Windows or windows emulation since I use windows threading, not posix threading, and I use the Microsoft MPI library. If the cloud system you are using is running Windows server 2008, then I could participate. Otherwise your proposal to standardize hardware may just become a way to exclude commercial programs.

I believe "hardware-open" tournaments are great and should not go away. But I also think "hardware-fixed" tournaments certainly do have their place and could provide very useful feedback. These tournamens do happen sometimes, e.g. the computer go tournament in Tampere this summer was with fixed hardware. (Well, almost. But at least no clusters.) If someone would organize a tournament e.g. using the EC2 hardware platform (and if the OS is UNIXy), Pachi would participate. -- Petr "Pasky" Baudis The true meaning of life is to plant a tree under whose shade you will never sit. _______________________________________________ Computer-go mailing list [email protected] http://dvandva.org/cgi-bin/mailman/listinfo/computer-go _______________________________________________ Computer-go mailing list [email protected] http://dvandva.org/cgi-bin/mailman/listinfo/computer-go
