Memory that gets 2 times slower, that's a *big* slowdown. > Two hops or more will happen on systems with *many* CPUs. And the average cost will be something like 1/n*80+a/n*115+b/n*150 ns (1+a+b=n). So the average would lie in the ballpark of 120 ns on an average system (and it will be less than 190 ns for a huge system). Thats ca 50% more than a normal memory access. Not to shabby. Thus algoritmic alterations could be possible that ammortize the cost of that extra 50%. I.e. Multi Probe, PV length two or more, et.c.But we will have to see the actual performance of the chip to be sure. MvH Dan Andersson
