Abstract: Embodiments include a processor capable of supporting multi-mode and corresponding methods. The processor includes front end units, a number of processing elements more than a number of the front end units; and a controller configured to determine if thread divergence occurs due to conditional branching. If there is thread divergence, the processor may set control information to control processing elements using currently activated front end units. If there is not, the processor may set control information to control processing elements using a currently activated front end unit.

Abstract: A method of compiling a program to be executed on a multicore processor is provided. The method may include generating an initial solution by mapping a task to a source processing element (PE) and a destination PE, and selecting a communication scheme for transmission of the task from the source PE to the destination PE, approximately optimizing the mapping and communication scheme included in the initial solution, and scheduling the task, wherein the communication scheme is designated in a compiling process.
