== 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

== 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
