What's the secret in getting Bright 0.2c to work on a Quad?

[Paul Bedrey]

I'm having trouble getting Bright 0.2c to run on my Quad.
The message I receive at load up is Bright 0.2cexe has stopped working (using Arena 1.99 beta 4, Bright loaded as UCI engine). Other programs such as Rybka and Glaurung work fine and utilize all 4 cores. I've noticed Bright 0.2c on the CCRL rating list using 4 cores so I know it does support 4 cores. I have no trouble with Bright on my Core 2 Duo using windows XP so I'm assuming its another Vista compatibility issue. Has anyone gotten Bright to run in Vista?

My quad core system is as follows:
Dell Inspiron 530
Processor is Intel Core 2 Quad @ 2.40Ghz
Memory 2 gig
32- bit operating system
Vista Home Premium

Hi all; Can anyone please tell me which processor is best for chess?
Thanks.

CCRL uses equivalencies, the machines that people use to submit games do only use 1 processor, but the time control that was selected is equivalent to the ratinglist.
As far as I know, there is no multiple core/processor supporting Bright, but they ran it at a time control that would've been slow enough to be considered in compensation for the one processor.

Xeon processors are best for chess currently in my opinion. Soon 45nm ones will be released publicly and the prices for the current 65nm ones will be dropped.

I'm not sure what you're alluding to, but CCRL uses quads for quad testing.

I think that you are misinformed. Bright currently supports multiple cpu's and you can adjust it by changin UCI Options, # of threads.

No, that never happens. 4CPU engines are run using 4 processors
