Web4.5 Execution of coarse-grained data-parallel applications. The distinction between fine-grained and coarse-grained paralellism introduced in Chapter 3 is important for understanding cloud software organization. Application developers have used the SPMD (Same-Program-Multiple-Data) paradigm for several decades for exploiting coarse … Webswitches, scattered global state, and coarse-grained locking lead to 62% of all cycles spent in instruction fetch stalls (fron-tend bound), cache and TLB misses (backend bound), and branch mispredictions (cf. [19]). These inefficiences result in 1.33 instructions per cycle (IPC), leveraging only 33% of our 4-way issue CPU architecture. Webin parallel, which we refer to as the coarse-grained parallel meth-ods. Such coarse-grained parallel approaches are straightforward to implement using the popular vertex-centric [37, 40] and edge-centric [55] graph processing frameworks. However, real-world graphs often exhibit a power-law or a log-normal distribution of vertex degrees [4, 11]. clean in between tiles
