Topics
Overview
- Current status of ITK-GPU
- Design strategy
- Implementation
- Usage example
- Patch in Gerrit
- GPU code testing strategy
Questions/Comments
- Asynchronous memory copy support
- Multithreading support (host)
- GPU driver will handle time-sharing
- Using time stamp class, mutex
- Global repository for GPU source code files and on-the-fly hard-coded headers generation
Action Items
- itkGPU* for general GPU class, itkOpenCL* for specific GPU implementation
- Pipelining using ITK factory mechanism
- Try subclassing BinaryThresholdImageFilter and SigmoidImageFilter so that we can experiment with using the ITK factory mechanism to use the OpenCL versions
- Inplace filter handling of the GPUImage
