Pete,

<3) Multi-tasking, and interrupt driven software, will cause disruptions to many optimizations performed by compilers for EPIC CPUs. They act like many mispredicted branches, cause major thrashes of the caches, and frequent pipeline stalls.>

How is this any different than any other CPU? Is'nt the nature of an interrupt the same across any CPU?

<The best market for EPIC CPUs is the embedded market as the problem can be very narrowly defined and does not change over time.>

How do you come to this conclusion given your previous point, 3)? Embedded systems are inherently real-time and heavily interrupt driven.

<The opposite of the things one expects from a general purpose CPU.>

Do you think Intel designed the Itanium as a general purpose CPU?

Also, explain what the issues are with regards to Java. Java on a client should not be an issue since Itanium is not intended as a client. Java on the server would ultimately run like any other executable written in any other language. Task switching is an OS activity and I would imagine properly written to take advantage of the underlying HW.
