-/**
- * High level abstraction for an OpenCL Kernel.
- * A kernel is a function declared in a program. A kernel is identified by the <code>kernel</code> qualifier
- * applied to any function in a program. A kernel object encapsulates the specific <code>kernel</code>
- * function declared in a program and the argument values to be used when executing this
- * <code>kernel</code> function.
- * CLKernel is not threadsafe.
