Returns a hint indicating the function of this task.

iterative "run" function for a GpuTask
The GpuDispatcher acquires the CUDA context for the duration of this function call, and it is highly recommended that the GpuTask use the provided CUstream for all kernels.
kernelIndex will be 0 for the initial call and incremented before each subsequent call. Once launchInstance() returns false, its GpuTask is considered completed and is released.
void pxtask::GpuTask::release | ( | ) | [inline, virtual] |
Release method implementation.
Reimplemented from pxtask::Task.
References NULL, and pxtask::BaseTask::removeReference().
void pxtask::GpuTask::setCompletionTask | ( | BaseTask & | task | ) | [inline] |
Specify a task that will have its reference count decremented when this task is released.
