摘要
The present invention is to provide a new method and apparatus for grasping working sets based on L1 / L2 latency characteristics that have not existed through various techniques such as a working set model and a stack model in order to dynamically grasp a working set of an application A hardware performance coefficient unit for monitoring performance characteristics including L1 and L2 resources usage and shelf entry counts of the cores, and a hardware performance counter for predicting data to be accessed next by the core based on the results monitored by the hardware performance counter A hardware shelf entry for pre-loading the data from the memory into the CPU cache before the data is accessed by the memory, and address access to identify the working set based on the predicted data loaded at the hardware shelf entry Use the PIN tool to identify the memory address that each workload accesses during execution. The shipment includes an extracting unit and a verifying unit for analyzing a memory reference pattern of an application based on a memory address extracted by the extracting unit, and verifying a working set size to allocate a memory.
