WebDec 1, 2024 · The programming framework used by Pregel, GraphLab, and so forth involved phased independent message exchanges between vertices. In each phase, a vertex could update locally and then send messages to neighbors; those messages would arrive in the next “super-step.”

WebAug 23, 2024 · The MapReduce programming model is widely used to parallelize data processing over the large scale of commodity computer clusters. However, on account of its monotonous data representation, it fails to express graph-parallel algorithms naturally and execute them efficiently.

In order to analyze the problems of Pregel, a sample graph that contains eight vertices and eight edges is used in Fig. 2 to describe the partition results in two partition algorithms, hash and metis .Though the partitions have the same size of vertices, the edge cut crossing two …
WebJan 1, 2014 · The architecture of Distributed GraphLab is similar to Pregel while the processing model is different: a user-defined update function modifies the state of a vertex based on its previous state, the current state of all of its adjacent vertices, and the value of its adjacent edges. An important difference between GraphLab and Pregel is in terms ... WebOct 27, 2015 · As the Argonne and Hortonworks researchers describe, “Graph/Z follows Pregel’s computing paradigm, to ‘think like a vertex’ wherein graph computation jobs are divided in terms of what each vertex needs to compute; edges are communication paths for transmitting results from one vertex to another and the computation is split into …
WebMay 26, 2015 · Pregel is designed to run on Google’s cluster architecture. The Pregel library divides a graph into partitions, each consisting of a set of vertices and all of those vertices’ outgoing edges. Weband GraphLab allow the user to adaptively prioritize computation. While both Pregel and GraphLab support dynamic computation, only GraphLab permits prioritization as well as the ability to adap-tively pull information from adjacent vertices (see Sec. 3.2 for more details). In this paper we relax some of the original GraphLab

WebJul 24, 2015 · Unlike Pregel, GraphLab relies on the shared memory abstraction and the GAS (Gather, Apply, Scatter) processing model which is similar to but also fundamentally different from the BSP model that is employed by Pregel. The GraphLab abstraction consists of three main parts: the data graph, the update function, and the sync operation. … beca andradeWebJun 25, 2024 · The basic idea of Pregel is that we implement an algorithm that is executed on every vertex of a graph.
