About FPU/SSE determinism

I have a question about determinism in FPU and SSE computations. Suppose thatI have a mixed sequence ofboth FPUand SSE instructions. Then I run it on different types of Intel microprocessors keeping the same starting conditions (general registers, FPU registers, memory etc). Will the final results be bit-by-bit equalon all processors? Are there any rules to predict and avoid undetermined results of FPU or SSE computations?

Thank you.

2.4ghz/533 fsb

Im having a problem with my 2.4 533 fsb p4. I bought this 2 years ago so i theew away my box and stuff for the motherbored i know i bought it from www.outpost.com.

IA32_CTL Model Specific Register

Hello,

My question is regarding the Model Specific Registers (MSRs) of the Pentium 4 family. I have been refering to the following application note -

IA-32 Intel Architecture, Software Developers Manual,
Volume 3: System Programming Guide

The MSR "IA32_CTL" located at address 0x17B (379)isdescribed asthe "Machine Check Feature Enable".

'cpuid' output and software licensing question

Hi
I am trying to use 'cpuid' instruction to get a unique number so I can use it for generating a license number for my application. I would like to know if it is possible to do such a thing with CPU id or I have to use some other methods like MAC address of a NIC card ?
I have read articles on the net about possibilty of using cpu id, but on the other hand some say that since it has privacy issues, Intel has dropeed embedding an id on its cpus
Any help regarding this matter is highly appreciated
Thanks
Hamid

Comment/Complaint re "Tired of Command Line"

Saw the headline as I logged into the site just now, and wanted to givethe Intel people reading thissome feedback. NO, I am not tired of the command-line environment. I want it! The fact that I can easily & simply do everything Iwant to do froma command line is, if not the primary reason I use Linux, at least one ofthe top two or three. I can do more work in a given time from the command line, with far less aggravation.

Kernel Registers in IPF

The Itanium Architecture for Software Developers talks about the Kernel Registers. It states:

The eight kernel registers, labeled Kr0 through Kr7, are used to convey information from the operating system to the application program. For instance, the operating system can put read-only, semi-static information such as processor ID into one of the Kernel registers.
