Performance Characterization of a Hardware Mechanism for Dynamic Optimization

By Brian Fahs, Satarupa Bose, Matthew Crum, Brian Slechta, Francesco Spadini, Tony Tung, Sanjay J. Patel and Steven S. Lumetta


We evaluate the rePLay microarchitecture as a means for reducing application execution time by facilitating dynamic optimization. The framework contains a programmable optimization engine coupled with a hardware-based recovery mechanism. The optimization engine enables the dynamic optimizer to run concurrently with program execution. The recovery mechanism enables the optimizer to make speculative optimizations without requiring recovery code
