To ensure proper portability and performance, the OpenCL kernel compiler can generate combined functions that can utilize various hardware resources for parallel execution of code, such as VLIW, superscalar execution, SIMD, SIMT, multicore, and multithreading. ICD drivers are supported.<br \/>\n(Installable Client Driver).
