iterative "run" function for a PxGpuTask
The GpuDispatcher acquires the CUDA context for the duration of this function call, and it is highly recommended that the PxGpuTask 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 PxGpuTask is considered completed and is released.

Release method implementation.
Reimplemented from PxTask.
References NULL, PxTask::release(), and PxBaseTask::removeReference().
|
inline |
Specify a task that will have its reference count decremented when this task is released.
|
protected |
A pointer to the completion task.
