There are many ways to measure "speed". While I have not looked at it in detail yet, I doubt that it will be 1,700 faster than DB for chess. However, it is interesting since the basic node is the p690, which can have up to 32 way SMP (1.3GHz). There are many configuration options utilizing IBM's Power4 CPUs, some with shared L2 cache (Power4 enables 2way on chip SMP), some with dedicated L2 and only one CPU per chip. They are packaged in MCM modules (much like mainframes), and each module has L3 and memory speed about 13GB/sec (to up to 256GB of memory). Thus each node is pretty much shared memory. Then you have to look at clustering, and it is unlear how many nodes will be supported. > >============ > >I am sold, have ordered the thing with my VISA card. > >Anxious waiting for delivery, start porting Rebel, increase the maximum depth to >256 ply.
