Understanding and modeling the synchronization cost in the GPU architecture

Large grain data flow (LGDF) programming is natural and convenient for describing digital signal processing (DSP) systems, but its runtime overhead is costly in real time or cost-sensitive applications. In some situations, designers are not willing to squander computing resources for the sake

This paper describes a circuit transformation called retiming in which registers are added at some points in a circuit and removed from others in such a way that the functional behavior of the circuit as a whole is preserved. We show that retiming can be used to transform a given synchronous

In contrast to the conventional send/receive model, the one-way communication model—using Put and Synch—allows the decoupling of message transmission from synchronization. This opens up new opportunities not only to further optimize communication but also to reduce synchronization overhead

transformations that affect data locality, achieved parallelism and synchronization and communication costs. We characterize this interaction using static analysis and generate a search space suitable for efficient automatic performance tuning. We also develop a heuristic based on number of threads; data reuse

For a program with sufficient parallelism, reducing synchronization costs is one of the most important objectives for achieving efficient execution on any parallel machine. This paper presents a novel methodology for reducing synchronization costs of programs compiled for SPMD execution

A “majority consensus ” algorithm which represents a new solution to the update synchronization problem for multiple copy databases is presented. The algorithm embodies distributed control and can function effectively in the presence of communication and database site outages. The correctness
