When the ARM weakly consistent memory model meets speculation: is it necessary?

Aggressive memory-level-parallelism techniques have provided significant performance gain in Distributed Share Memory Designs. In this paper, we reevaluate speculative memory ordering in the context of Chip Multi-Processors (CMPs) and power-limited computation. We evaluate relative performance between Sequential Consistency, Total Store Order and Relaxed Memory Order on a selection of modern workloads to predict the performance of the ARM weakly consistent memory model.
