Re: ACCA challenge match: Buzz vs Symbolic

It's interesting that the same opening (SOC 3209, KID 3. Nc3) came up twice in four games as Symbolic's ICC book is rather wide with just over five million positions. Symbolic was running on a fast processor (2.66 GHz Xeon), but with relatively small transposition tables. The box has only 1 GB RAM a...

Re: Symbolic Status Report: 2007.04.07

First, there's only a rudimentary search in place for testing purposes. Eventually the search will expand that portion of the tree that will most likely to confirm or deny that the first move of the current predicted variation is the best move in the position. The whole tree is kept in memory as tha...

Re: crafty game and log files

If you don't want any of the game or log files, it's possible to use Crafty's shell escape command to automatically delete them. Have a shell escape in the initialization file call a batch file to do a wildcard delete of the unwanted files.

Re: WCSAC: nineteen possible cooks

You've got me thinking here. Perhaps I should get a small UPS to power the DSL modem and the wireless router, so I can still use a laptop to connect during extended outages. I have one of those Apple notebooks with an ambient light sensor that's used both for the display backlight and the illuminate...

Re: WCSAC: nineteen possible cooks

The EPD analysis output file is line buffered.

I'm not getting a UPS as there aren't any affordable ones that can last for fourteen hours. And it's not worth the money for a cheap, limited UPS just to have a graceful shutdown.

Re: WCSAC: nineteen possible cooks

The WCSAC cook scan has now entered the 65536 second iteration. So a couple more weeks at most and let's hope for no power outages. Speak of the devil, a snowstorm yesterday caused a power outage fourteen hours long. I'll have to restart the analysis. And maybe go shopping for a snow-powered comput...

Re: My quad core MacPro was at the top until an hour ago

A correction: it's Clovertown, not Cloverleaf. Intel takes it's chip names from the names of rivers in the US Northwest.

My quad core MacPro was at the top until an hour ago

My quad core MacPro was at the top of Apple's profesional model line until an hour ago. The octo core Cloverleaf Xeon model has been announced. See: http://www.apple.com/macpro/ The base 3 GHz octo core starts at US$3,997, rather more than I paid for my 2.66 GHz quad core. My model is still availabl...
