DirectCompute Lecture Series 110: Memory Patterns

17 minutes, 45 seconds


Right click “Save as…”

In this video, Matt Sandy, a Program Manager on the DirectX team, provides an in-depth look at memory usage patterns in DirectCompute.

In this lecture, you will learn how to most effectively use memory in DirectCompute. Topics include an overview of how memory resources are used within a DirectCompute application, methods for identifying execution threads, data I/O patterns for various resource types, and how to utilize groupshared memory to improve application performance.

Slides for this lecture are available from here.

This video is a follow up video for:
The DirectCompute Expert Roundtable Discussion
the Introduction to DirectCompute video.

For more information about DirectCompute, download the PDC 2009 DirectCompute Hands on Lab.

For more information about DirectX, check the DirectX Developer Center and the Windows Developer Center.

You can also download the Direct X SDK.

  • High quality WMV are worse off than regular ones. Same problem with other videos in this series Sad

  • Gus Classgclassy Helping developers rock at coding for Windows!

    Bummer, I will see what I can do to look into this.  Also, we'll be looking into creating other higher fidelity versions that run in a special interface - there are publishing challenges to that so it might take a little while longer.

    I'm not seeing this at all. The high res quality is, well, high... What problems are you experiencing, exactly?

  • Interesting video but i would have like to see what the example shader code produced, ex a small video clip like that particle demo

  • The shader code samples were meant to be as simple as possible in order to convey just the core concepts (and fit on a single slide Smiley ).  If you'd like to see more of it in action, check out the SDK samples and the hands-on lab from PDC 2009.
