Folks,
I'm still trying to resolve NTP on Windows Vista. I do have a dual-core
system, so I was wondering how NTP handled dual-core. Does it discipline
both cores, and is a special start-up switch required? Should I define
the affinity for NTP to a single core?
Looking at the AMD Web site,

Looking at the AMD Web site, they do have a utility to sync the two
cores - AMD Dual-Core Optimizer - under certain circumstances. I
tried to install this on Vista, but a file appears to be missing!
Fixed by using Run as administrator.

David,
The multiple-CPU nanokernel code that left here and is in the Alpha
kernel assumes each CPU has an individual cycle counter and the timer
interupts are vectored to a designated CPU. There is a data structure
associated with each CPU that holds the measured current cycle counter
scaling
Does anybody know of any *practical* samples on how to
implement NTP/SNTP client?. The goal is to provide accurate
time for a program/client running on Windows Vista.
Specifically, what values to include in the the request message,
how to process the reply message, etc.

Have you seen the sntp directory in the reference implementation tarball?

Why not just run NTP?

Yes. And one missing step:
After stopping ntpd, ntpdate -b [server].
The single most common cause of a large negative drift value
is a system whose clock has not been initialized before starting
ntpd (or has been stopped during a large time adjustment).
What vintage of ntpd are you using?

I think I found out where the problem is.
VxWorks doesn't have adjtime( ), and the one we wrote wasn't doing
anything. That's what makes the drift to increase to +500 (I think).
Does that make sense??
We would like to know what adjtime( ) actually does, so we can rewrite
it

While I would agree with you in general, we don't have any real idea
what the Windows code is doing whether or not it is a uniprocessor or
multiprocessor. I very much doubt that they duplicated your work though
I would think that it's very important for the CPU's to keep each other

Hi Harlan Stenn,
As per your suggestion I would have used the existing NMEA
reference clock driver
for Accord GPS Clock. But there are certain issues as listed below.
1. Accord GPS Clock spits out NMEA at 9600 baudrate
2. It has custom NMEA format for GPS (and the driver is
