CPU's ON HYPERTHREADING in 2003

[Guest]

Hello,
I know this is for 2000 and my question is for 2003 but i didn't see a group for 2003
so i am posting it here.
I have a 4 way machine hyperthreading enabled is there a way to know which are physical and logical processeors because i want to set up affinity task for sql server when i am doing this i don't want to assign all the logical processores to the
sql server and leave physical cpu's to some othere app.
for ex: i have 0 1 2 3 because of hyperthreading i see them as
0 1 2 3 4 5 6 7..so which ones win 2003 see's as Physical and logica.

Thanks,

Processor enumeration on computers that use hyperthreading first assign
processor numbers to the primary logical processor for each processor
and then assign numbers to the secondary. For example, for dual physical
processor computers with hyperthreading, the first processor has logical
processor 0 and 2, and the second processor has logical processor 1 and
3. The third-party products that are discussed in this article are

So Logicals would be 4,5,6 and 7
