Abstract
A method, computer program product, and computer system are provided. An enhanced compiler identifies instructions for execution among them, instructions directed to an inner computation unit of a CPU core. In response to identifying instructions directed to the inner computation unit, locating in a system call table a system call to indicate a begin of an executable code block of instructions that are directed to the inner computation unit of the CPU core. The enhanced compiler searches the system hardware registry for the parameter corresponding to the inner computation unit of the CPU core. The system call is inserted as an interrupt instruction in the compiler output at the begin of the executable code block of instructions that are directed to the inner computation unit of the CPU core. The enhanced compiler executable code output is saved for later selection by a scheduler of an operating system.
