Topics

Overview

• Current status of ITK-GPU
  • Design strategy
  • Implementation
  • Usage example

• Patch in Gerrit
  • http://review.source.kitware.com/#change,673

• 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
