AUTOMATIC ASYNCHRONOUS OFFLOAD FOR MANY-CORE COPROCESSORS |
摘要 |
Methods and systems for asynchronous offload to many-core coprocessors include splitting a loop in an input source code into a sampling sub-part, a many integrated core (MIC) sub-part, and a central processing unit (CPU) sub-part; executing the sampling sub-part with a processor to determine loop characteristics including memory- and processor-operations executed by the loop; identifying optimal split boundaries based on the loop characteristics such that the MIC sub-part will complete in a same amount of time when executed on a MIC processor as the CPU sub-part will take when executed on a CPU; and modifying the input source code to split the loop at the identified boundaries, such that the MIC sub-part is executed on a MIC processor and the CPU sub-part is concurrently executed on a CPU. |
