Digidesign - Software engineers @ WWDC

[Targon]

I hope Digidesign sent their Software engineers to the following WWDC sessions, hopefully they will learn something they have previously failed to ensue in Pro Tools.






How to Thread Your Application with the MP APIs

Tuesday, 3:30 - 5:00

The Mission *

Learn how to leverage the threading architecture in Mac*OS*X with single and multiprocessor hardware to significantly boost the performance and responsiveness of your application. This session will discuss the threading models available in Mac*OS*X and will show a step-by-step approach to threading. We'll use the Carbon multiprocessing APIs to thread a tight loop to gain a performance boost, and discuss how to use semaphores to notify the main thread once computation is done.



Optimizing for the Power Mac G5

Thursday, 9:00 - 10:30

The Mission *

The 64-bit G5 processor and high-bandwidth architecture make the Power Mac G5 a breakthrough in processing power. Come to this session to learn how to unleash all the power of the Power Mac G5 platform. We will focus on optimization for the G5: memory I/O, using the Velocity Engine, Mach-O, threading, loop unrolling, loop alignment, gcc G5-specific flags and other ways you can optimize your code for this powerful platform.



Maximizing Performance: Got Shark?

Friday, 3:30 - 5:00

The Presidio *

Want to get the best performance out of your Mac*OS*X application? This session is all about performance: How to think about it, How to measure it, and How to improve it. We will go in depth on how developers can use Shark—one of the performance tools that ships with Xcode—to identify performance problems related to memory bandwidth and algorithmic issues, and we will describe some new features that make Shark an even more powerful performance tool.



Mac*OS*X Kernel Programming

Wednesday, 2:00 - 3:30

The Marina

The Mac*OS*X Kernel changed significantly in order to provide better SMPperformance, fine-grained locking, and support for 64-bit applications. In orderto support those changes, and to provide a stable and efficient environment,Apple has formalized the APIs used by Kernel Extensions. These formal APIs,known as Kernel Programming Interfaces (KPIs), will be better defined andsupported from release to release of the kernel. This session will describe thechanges that motivated the creation of KPIs, their effects on some kernelprogramming techniques, the introduction of KPIs into the kernel, and how theywill continue to evolve.

I would have hoped they'd be there no matter what.
