Does the number of CPU's returned

We need to configure our tempdb files according to
http://support.microsoft.com/default.aspx?scid=kb;en-us;328551
and I need to know how many physical CPUs on each server.
thanks people.

-- cranfield, DBAI beleive that hyper threaded installs DO show the hyper CPUs , so you will
see double the CPUs.... You also may wish to reduce the number of CPUs that
sql can use and/or reduce the MAXDOP setting.

We've been hitting the errors as described in the below KB and I need to
rollout these tempdb changes to 150 SQL Servers. Problem is not all of them
are the same and hence the need for me to write a script that will make the
following changes to TEMPDB and batch it out to all the servers:
1) Turn off auto grow. Pre-allocate space for tempdb files.
2) Make as many tempdb files as there are CPU's (accounting for any affinity
mask settings)
3) Make these file sizes of equal amounts
So I need to know the number of physical CPUs.
Do you know if KB328551 refers to physical or logical CPUs?
thanks again

MAXDOP should never be set higher than the number of actual physical
processors.
However, the issues being addressed in this KB don't apply simply to
parallel queries, the issue could easily (and more lilkley in fact...)
happen in a high volume OLTP situation where no queries may be parallel.
So, I woudl recommend configuring the number of tempdb files based on the
total number of logical processors currently in use by SQL Server.
