From LINQ to SilverLight – Watch videos and hear about all the cool technologies coming and the people behind them. http://channel9.msdn.com/Tags/arun+kishan en Wed, 19 Jun 2013 18:06:58 GMT Wed, 19 Jun 2013 18:06:58 GMT Rev9 3 1 25 Inside Windows 8: Arun Kishan - Windows App Model Arun Kishan digs into the low level details of Windows 8's new application model.

How has Process Lifetime Management (PLM) been reimagined in Windows 8? How does app suspension work, exactly, or, what happens when an app is no longer in the foreground and not closed? How much work can you do in the background when an app is suspended? Arun covers several topics here, so please do set aside some quality time. In return, you will gain new levels of deep understanding that will help you take advantage of the Windows Store App platform and build excellent modern Windows applications.

You've met Arun before, so you should be prepared for some very deep treatment of this new world for Windows and Windows developers. This is an excellent 400 level investigation of the core changes that support the new app model.

Huge thanks to Arun for another exceptional conversation and whiteboard session.

Tune in. Learn.

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!

One of Mark’s favorite kernel innovations is the way the Windows 7 kernel manages scheduling of threads and the underlying synchronization primitives that embody kernel thread management.

Prior to Windows 7 (and therefore Windows Server 2008 R2) the Windows kernel dispatcher employed a single lock, the dispatcher lock, which worked well for a relatively small numbers of processors (like 64). However, now that we find ourselves in the midst of the ManyCore era, well, 64 processors aren’t that many... A new strategy was required to scale Windows to large numbers of processors since a single lock is limited in capability, by design: The masterful David Cutler, one of the world's greatest software engineers, wrote the NT scheduler in a time when the notion of affordable 256-processor machines was more science fiction than probable. 

As we learned in the Mark Russinovich video, Windows 7 can now scale to 256 processors thanks to the great engineering of Arun Kishan, a kernel architect you've met on C9 back in the Vista days. In order to promote further scalability of the NT kernel, Arun completely eliminated the dispatcher lock and replaced it with a much finer grained set of synchronization primitives. Gone are the days of contention for a single spinlock. How did Arun pull this off, exactly, you ask? Who is this genius? Well, tune in. Lots of answers await…

Arun's work directly benefits the overall performance of Windows running on many processors and means, simply, Windows can now really scale. Thank you, Arun!

 

Spinlocks are synchronization primitives that cause a processor to busy-wait until the state of the lock’s memory location changes.

 
As the name implies, the dispatcher lock is the fundamental lock associated with the kernel dispatcher, or the scheduler.
