Abstract: "The fine-grain nature of shared-memory multiprocessor communication introduces overheads that can be substantial. Using the Scalable Coherent Interface (SCI) as a base hardware platform and the SPLASH benchmark suite for applications, we analyze three techniques to reduce this overhead: (i) efficient synchronization primitives, and in particular a hardware primitive called QOLB; (ii) weakened memory ordering constraints; and (iii) optimization of the cache-coherence protocol for two nodes sharing data. We perform simulations both for current technology and technology that we anticipate will be available five years hence. We find that QOLB (of which this study performs the first detailed simulations) shows a large and consistent improvement, much larger than that predicted by Mellor-Crummey and Scott [19]. The relaxation of memory ordering constraints also provides a consistent performance improvement. In accordance with prior results, we show that a more aggressive memory model produces more substantial performance improvements. The optimization for two-node sharing shows mixed results, correlating unsurprisingly with the presence of that sharing pattern in an application. Our most important results are (i) that the overheads eliminated with these optimizations are largely orthogonal -- the performance gains from supporting multiple optimizations concurrently are for the most part additive -- and (ii) that technological improvements increase both these overheads and the success of the optimizations at reducing them."

Book Description
Beginning with a discussion of the fundamentals of scalable multiprocessors and the characteristics of large-scale parallel programs, the book then presents an in-depth presentation of the hardware design issues for this class of machine, and a survey of existing and proposed scalable shared-memory systems.
