yaoxing said:Windows NT Workstation 4.0 (1 to 2 CPUs) was the first Microsoft OS that supports SMP. Windows NT Server 4.0 (1 to 4 CPUs) as well.
Then followed by Windows 2000 Pro (1 to 2 CPUs), W2k Server (1 to 4 CPUs) and Win2k Advanced Server (1 to 8 CPUs).
And then Window XP Pro (1 to 2 CPUs)
Then Windows 2003 Server, etc...
Windows 95 (all releases), 98, 98SE, ME do not support SMP. Having two CPUs in your system does not give you any advantage.
I also read somewhere also that Intel P4 HT works only on Microsoft Windows (correct me if I'm wrong). Try installing Redhat on your HT-enabled PC and see whether it will detect the system as an SMP system. If not, then you should know what it means. It seems more like a "software" SMP. Perhaps it takes a Linux geek to come up with a new kernel for that purpose.
Feel free to correct me if I'm wrong. :sweat:
Intel Hyperthread support anything that has Hyperthreading code written on it. As long as the code is corresponding with the processor, there is no difference whether it is Windows or Unix.
There is already SMP in Linux ... years ago ...... The graphics in Titanic was processed by a Linux SMP farm with 256 processors
