Hi

There's a way to do this?
Normally I must switch of one CPU by the task manager.

TIA

If it is important for performance for an application to use one only
processor in HT, then the software vendor should provide a program option to
set this.

There are few programs that do not benefit from HT. For dual core, I
wouldn't worry about it. Server class programs EQ MS SQL Server 2000 works
better on 1 HT processor - you can set processor affinity in Enterprise
Manager. Other server class software should provide similar functionality -
ask the vendor.

If it is important from a s/w license perspective, then ask the vendor.
If the s/w is buggy on SMP, then submit bug reports to the vendor :)
Consider moving the process to single CPU system.

You can always switch off HT. With a SMP system, a good reason would be
needed.

If the reason has not been covered, then what is the reason?

The above article is a bit specific, but the utility the author wrote may be
worthwhile.
