The short version of how it is done for optimization, which I believe is all TJ was/is thinking of doing, is to split the load into multiple tasks and assign those tasks to different threads each one of which would use a different CPU and / or Core.
For example in a two variable optimization where each variable can be varied from 1 by 1 to 100 there are 10,000 combinations. It is simple enough to determine ahead of time the pairs ( in this case ) and then assign half to one task and half to another and then fire up each task to use different CPU's / Cores. This is in essence what IO does using multiple machines with IO being the traffic cop to manage assigning tasks and communicating back and forth via TCP/IP scokets with each of the machines that the load is spread over. --- In [email protected], "Fred" <[EMAIL PROTECTED]> wrote: > > AB does not TODAY make use of multiprocessors or even multi cores. > > However, TJ stated awhile back that this would be available in the > not too distant future.
