It’s Time To Look At Windows 7
Microsoft has released a beta of its new OS, Windows 7, as well as some details about its functionality.
If you want to install the beta, you should start with this information from TechNet. Even more detail is provided by Mark Russinovich, with his Inside Windows 7 interview. Here is an excerpt from this article:
One very important change in the Windows 7 kernel is the dismantling of the dispatcher spin lock and redesign and implementation of its functionality. This great work was done by Arun Kishan (you've met him here on C9 last year). The direct result of the reworking of the dispatcher spin lock is that Windows 7 can scale to 256 processors. Further, this enabled the great Landy Wang to tune the Windows Memory Manager to be even more efficient than it already is.
This is some exciting stuff, especially as it pertains to scalability. I’ll have to look and see how synchronized the Windows 7 kernel is with the Windows Server 2008 R2 kernel. In any event, this should have tremendous implications for server and desktop virtualization, in addition to other high-level engineering applications. Even the HPC (High-Performance Computing) market will benefit from this.
I should have a copy of the beta installed before month’s end, at which time I will provide a summary first look.
