WebEvery cycle (v1, v2, . . . , vk, vk+1 = v1) is detected by all vi,i = 1 to k in the same iteration; it is reported by the vertex min {v1,...,vk} (see line 9 of Algorithm 1). The total number of iterations of the algorithm is the number of vertices in the longest path in the graph, plus a few more steps for deactivating the final vertices. WebWe present Resilient Distributed Datasets (RDDs), a distributed memory abstraction that lets programmers perform in-memory computations on large clusters in a fault-tolerant manner. RDDs are motivated by two types of applications that current computing frameworks handle inefficiently: iterative algorithms and interactive data mining tools. In …
