Support for Hyper-threading on P4

Post by Mathieu Dube-Dallaire » Mon Dec 16, 2002 5:44 pm

Hi,

Just a quickie: Does QNX v6.2 support hyper-threading (as available on
Pentium 4 arch.)? Any plan to do so?

Yes. Although there are no hyper-threading optimizations in the 6.2.0
SMP kernel, it treats the system as N phyiscal CPUs.
