Mark Russinovich: Inside Windows 7 Redux

Windows 7 is here, available to all for purchase and ships today with new PCs! To celebrate this momentous occasion for Windows and Microsoft, Technical Fellow Mark Russinovich joins me in a discussion that extends the great conversation we had last year on Windows 7 internals. In his previous C9 interview, Mark told us about many of the new additions to the Windows kernel which enable Windows 7 (and Windows Server R2) to scale to large numbers of processors. Well, removing the kernel dispatcher lock is not all that the great Arun Kishan did. He also developed a new scheduling mechanism known as Distributed Fair Share Scheduling (DFSS). Mark describes what this is and how it works.

We also discuss NUMA, non-uniform memory access, (and Mark explains NUMA to us while showing a demo or two on a 256 processor machine!)

Moving on to Windows memory management, the domain of the great engineer Landy Wang, Mark discusses the new additions to the Windows Memory Manager and explains why they matter to those of us who spend all of our time and in user mode.

Learn about all of this and much more as Mark digs into the insides of Windows 7, way deep down in the system (the culmative effects of which help to make Windows 7 Microsoft's most reliable, scalable and efficient general purpose operating system to date). As usual, Mark explains very complex mechanisms and concepts in a readily understandable way. This is a very conversational piece and we cover a lot of ground in a relatively short period of time. We also learn exactly why Mark is so passionate about operating systems and what the spark was that set off his passion and curiosity of how things work internally.

Mark will be presenting at PDC09 in the Technical Leaders track and the free Windows 7 Developer Boot Camp. His talks will be very deep and will explore all aspects of the new, improved Windows 7 kernel. I highly recommend that you attend both of these talks if you are going to PDC (you're going, right?!).

Check out the Windows area on 9 for more great Windows 7 content, all rolled up into a nice experience!

Enjoy!

What is that tool that let's you draw on the surface of any window? Like, screen paint?

Manycore killer "application"? Raytracing. Smiley

Impacts gamers (pretty many of them) and 3D software in general

(And that's right Charles: peeking our interest with future trends is much appreciated)

Welcome Change

Mark oversees the development and evolution of the Windows kernel... That's an ambient truth in our conversation(s) with him, right? Smiley

 

All new or updated kernel components do not emerge without Mark's involvement. And Mark has put SysInternals machinery into Windows.

LOL! Charles, Mark actually made you speechless at many points during the interview, including the very end. He's a real hard core technical dude to talk to, isn't he and I see you really respect him as do we all!

 

Thanks for the interview...
