Linear deterministic greedy partitioning ldg
Nettet18. jun. 2024 · For solving large-scale consistent systems of linear equations by iterative methods, a fast block Kaczmarz method based on a greedy criterion of the row selections is proposed. The method is deterministic and needs not compute the pseudoinverses of submatrices or solve subsystems. It is proved that the method will converge linearly to … Nettet24. feb. 2014 · Regarding edge partition, linear deterministic greedy partitioning (LDG) [18] considers using a greedy algorithm to put neighbor vertexes together during …

Nettet27. nov. 2024 · The goal of Linear Deterministic Greedy (LDG) is to assign the vertex into the subset with the largest number of its neighbors according to the load of cluster nodes. LDG is applied in heterogeneous parallel environment because it is easy to implement and excellent partitioning effect in a series of streaming algorithms [ 27 ]. Nettet13. sep. 2024 · Linear Deterministic Greedy partitioning (LDG) uses a greedy heuristic that assigns a vertex to the partition containing most of its neighbors (Stanton et al. 2012). Petroni et al. ( 2015 ) proposed HRDF to effectively partition power-law graphs by cutting the high degree nodes to radically reduce the number of vertex-cuts.
Nettet12. aug. 2012 · Existing graph partitioning heuristics incur high computation and communication cost on large graphs, sometimes as high as the future computation itself. Observing that the graph has to be loaded into the cluster, we ask if the partitioning can be done at the same time with a lightweight streaming algorithm.
