The follow infomation from the T2000 and we can see only 16 logical processors.
But the Chapter 3. "Scheduling Classes and the Dispatcher" which from the book
named
"Prentice.Hall.PTR.Solaris.Internals.Solaris.10.and.OpenSolaris.Kernel.Architecture.2nd.Edition.Jul.2006.chm"
, says that T2000 has 32 logical processors.
"For the typical configuration of a fully loaded T1000 or T2000, with eight
execution cores, each with four hardware threads per core, Solaris will
configure (8 x 4) 32 processors, each with its own set of dispatch queues."
Is there some mistake on my T2000?
thanks !!
