This has been discussed in other threads. The 64 bit processor may be able to do more "useful work" in a single clock cycle than the current 32 bit processors can do, depending on the design of the processor. Clock rate is not a true indication of the amount of useful work that can be done in a given amount of time. In other words, a 64 bit processor, if properly utilized by the programmer, may be preferable over a 32 bit processor with a faster clock rate. We have different KINDS of processors to consider, too. > >Even if they want to use 64bit, they can use windows, no need to get UNIX, or >port it on UNIX. Again, "discussed already in other threads." Whether or not there is a need depends on availability of the necessary hardware, including boards. The required availability is in doubt. It is not clear to me that the necessary hardware is available for a Windows implementation. Someone mentioned a specific number of nodes per second. [6,000,000 per sec?] If that's true, then choice of the TYPE of processor implies a specific clock rate. In other words, the implied clock rate would depend on the processor. Choice of a "better" processor might offer some relief on required clock rate. [Forgive me for saying the same thing several different ways. That's just the way I think. Looking at several different "flavors" of the same thought.] > >pavs Bob D.
