Abstract
In a sectored cache, a cache line is divided into several subblocks. Each subblock is a basic coherence unit. In this way partial block invalidation can be done on cache coherent multiprocessors. Bounteous transfer is a scheme in sectored caches in which a subblock holder supplies extra subblocks after transferring the missed subblock on a read miss. In this paper, we investigate the effectiveness of three different types of bounteous transfers: bounteous transfer with valid subblocks (BT-V), bounteous transfer with clean subblocks (BT-C), and bounteous transfer disabled (No-BT). We simulated the execution of typical benchmarks, FFT, LU, Radix, SOR, on sectored caches. Two metrics U-rate and R-rate are proposed to help observe the sharing granularities and coherence overhead more precisely. Evaluation results show that different benchmarks work better with different kinds of bounteous transfers and using bounteous transfer carelessly may result in performance degradation. Ke...
