All of this with 32 RISC processors. I believe they can build it. But I think you will find it very difficult to program. Every system that requires programs to be decomposed into cooperating loosely coupled parts to get full performance has hit this wall. >Thank you for your advices.

It'll certainly be a learning experience, even if what you learn is "don't do that again." Good luck. R's, John
