SAL, Security, Settings, and the Safe-CRT: Writing Robust Code Made Easy 

Bruce Dawson

Writing robust code is always difficult, especially when hackers actively look for ways to crash or exploit your game. Using SAL annotations and the compiler's /analyze feature make it easier to find potential problems in your code. Also, proper use of the secure CRT makes fixing many of the problems easier, and choosing the right compiler and linker switches can substantially mitigate the problems of bugs that don't get fixed. See how a machine gets pwned, and how these techniques prevent it. This talk covers Windows and Xbox 360, VC++ 2005 and VC++ 2008.  

Using VMX and SSE Instructions for Performance

David Cook

CPUs today have large amounts of mathematical processing power and few applications take full advantage of it. Through a low-level deep dive on optimization and counter examples, this talk explains some of the most used VMX instructions for the Xbox, SSE2 instructions on PC, APIs that use vectorized data, and memory alignment issues in dealing with vector operations.

Join us to find out and learn about the latest compression techniques, APIs, streaming analysis tools, streaming techniques and using the hard drive cache effectively. We also discuss topics on content distribution and glimpse into what kinds of improvements are planned for future XDK releases. Finally, we review successful techniques that current shipping titles have utilized.

Microsoft Directions in Parallel Computing and Some Short Term Help

Bruce Dawson

This talk focuses on the native task scheduler being announced by the Parallel Computing Platform group in Microsoft this spring and offerings that are available in the XDK. The scheduling of tasks within games can improve resource utilization, load balancing, and performance. For games targeting the current generation of PCs and the Xbox 360 console, we discuss an interim solution. Previous talks given on this topic laid the foundation for using tasks to move work required by the engine from an over-utilized hardware core to an underutilized core. A progression of task and scheduler designs is presented that start with simple implementations and move to more complex designs that have low-overhead. The simple implementations are satisfactory for a small number of tasks but impose a prohibitive amount of overhead when the number of tasks grows. Finally, we present the work-stealing algorithm that pulls work from one core to another in the low-overhead scheduler.

Here Be Dragons: C++ Undefined Behaviour

Bruce Dawson

C++ allows game developers to wring awesome performance from gaming platforms while also providing language abstractions that make it possible to deliver incredibly rich titles. But there is a cost to be paid, and the cost is high. In order to give implementers maximum flexibility, many areas of the C++ language are purposefully unspecified. Developers can unwittingly rely on unspecified or undefined behaviour, because compilers are not obliged to report those errors (nor can they report errors in many cases). Come learn how to navigate the deadly waters of undefined behaviour.

Networking, Traffic Jams, and Schrödinger's Cat

Mitch Walker

The XNA Framework networking API makes it easy to join a session and exchange data packets. But what exactly should you put in those packets? This talk explains how to overcome the challenges posed by limited bandwidth (if you send too much data, or fail to properly compress it, your game could end up even slower than my morning commute) and delivery latency (when packets arrive late, you must use prediction algorithms to smooth things out, creating a strange quantum world where each object has more than one state being simulated in parallel).

Building Worlds with the Content Pipeline

Frank Savage

Real games need more than just one mesh. They require spawn points, trigger boxes, and collision skins. A game level is not just an input to the graphics engine, but must also contain information about collision detection, sound, game logic, and AI. Most games also contain more than one level. This talk discusses how to extract rich level metadata using the XNA Framework Content Pipeline, and how to drop down to the underlying MSBuild technology when you need to build large amounts of content in a scalable and performant manner.

Taking Xbox LIVE Arcade Games to the Next Level

Dan Maher

LIVE and Arcade offer many tools and services that developers can use to make their games even more appealing. This session gives examples of some of the many innovations in Arcade games. Also, considering that the most important tool in selling a game on Arcade is the trial, this session presents best practices for how to design a trial experience that optimizes conversion.

Integration APIs for MSN Site and Messenger Games

Alexey Kouzmitch

Two of Microsoft’s most widely deployed gaming platforms, MSN Games and Windows LIVE Messenger, both offer APIs for deploying Flash-based or custom ActiveX control–based game titles. This session gives an overview of both APIs as well as the development environment and tools for each.
