A hardware environment for low-overhead profiling (HELP) technology significantly reduces profiling overhead and supports runtime system profiling and optimization. HELP utilizes a specifically designed embedded board. An embedded processor on the HELP board offloads tasks of profiling/optimization activities from the host, which reduces system overhead caused by profiling tools and makes HELP especially suitable for continuous profiling on production systems. By processing the profiling data-in parallel and providing feedback promptly, HELP effectively supports on-line optimizations including intelligent prefetching, cache managements, buffer control, security functions and more. |
