Energy-Effectiveness of Pre-Execution and Energy-Aware P-Thread Selection

Abstract	Pre-execution removes the microarchitectural latency of "problem" loads from a programýs critical path by redundantly executing copies of their computations in parallel with the main program. There have been several proposed pre-execution systems, a quantitative framework (PTHSEL) for analytical pre-execution thread (p-thread) selection, and even a research prototype. To date, however, the energy aspects of pre-execution have not been studied. Cycle-level performance and energy simulations on SPEC2000 integer benchmarks that suffer from L2 misses show that energy-blind pre-execution naturally has a linear latency/energy trade-off, improving performance by 13.8% while increasing energy consumption by 11.9%. To improve this trade-off, we propose two extensions to PTHSEL. First, we replace the flat cycle-for-cycle load cost model with a model based on a critical-path estimation. This extension increases p-thread efficiency in an energy-independent way. Second, we add a parameterized energy model to PTHSEL (forming PTHSEL+E) that allows it to actively select p-threads that reduce energy rather than (or in combination with) execution latency. Experiments show that PTHSEL+E manipulates pre-executionýs latency/energy more effectively. Latency targeted selection benefits from the improved load cost model: its performance improvements grow to an average of 16.4% while energy costs drop to 8.7%. ED targeted selection produces p-threads that improve performance by only 12.9%, but ED by 8.8%. Targeting p-thread selection for energy reduction, results in "energy-free" pre-execution, with average speedup of 5.4%, and a small decrease in total energy consumption (0.7%).
