Standard approach to the cpu is getting to the limit. New technologies could emerge. The future is hard to predict. One approach has not yet being published in Go, that is the special purpose cpu. One probably should start getting familiar with terms of digtal design, such as barrel shifter and

It would please me to have all the gaps filled like this, but it's a matter of getting them to play on the server. In a related issue, I plan to build a weak player into the server. This would be a player who's only function would be to provide an opponent so that no players has to wait out a ro

While working Pebbles up the ladder, there are times when Pebbles was squarely in the middle of a huge gap. For example, there was a time when the opponents were Aya (~2300) and AverageLib (~700). That is pretty extreme. But even now the next higher rated opponent is +200 and the next lower rated o

Tilera works well for computations that do not require a lot of memory, for example video transformations, or packet processing. It probably won't work so well for computations that require all processors to have access to off-chip memory, since the memory bandwidth per processor is much lower tha

Cool, but what is the cost? The website doesn't even have a word about how to obtain thier product. Insane, IMO. http://www.google.com/products?q=tilera returns ONE (useless) hit. Or is this chip not yet released? David Fotland wrote: Lots of simpler cores is possible, but only for running

The advertisement claims that an OS can be installed on each core including linux. So I don't know why you say it's no good for general computing. I think you mean each core is far less powerful than a core 2 duo core? I have not looked at the overview paper yet, but it seems like there is no p

Lots of simpler cores is possible, but only for running specialized code that doesn’t need much memory or memory bandwidth. If I have thousands of cores with small caches the total bandwidth to off-chip memory will be way too high, and performance will be limited by external memory throughput. Lo
