Explicit Communication and Synchronization in SARC

Explicit Communication and Synchronization in SARC
SARC merges cache controller and network interface functions by relying on a single hardware primitive: each access checks the tag and the state of the addressed line for possible occurrence of events that may trigger responses like coherence actions, RDMA, synchronization, or configurable event notifications. The fully virtualized and protected user-level API is based on specially marked lines in the scratchpad space that respond as command buffers, counters, s. The runtime system maps communication abstractions of the programming model to data transfers among local memories using remote write or read DMA and into task synchronization and scheduling using notifications, counters, and queues. The on-chip network provides efficient communication among these configurable memories, using advanced topologies and routing algorithms, and providing for process variability in NoC links. We simulate benchmark kernels on a full-system simulator to compare speedup and network traffic again...
