An Efficient Transaction-Based GPU Implementation of Minimum
The Boruvka’s algorithm for calculating MSF has the most expressed parallelism; however it is a challenging irregular algorithm to implement on GPUs
What is spanning tree and Boruvka's algorithm?
- Here we will learn about the spanning tree and Boruvka’s algorithm. After that, we will see the C++ program for the same. A spanning tree is a subgraph of a graph G, which has all the vertices connected with the minimum possible edges. Hence, if the graph G contains v vertices than the spanning tree of G also contains v vertices and v-1 edges.
How to find minimum spanning tree using Kruskal's algorithm?
- There is a connected graph G (V, E) and the weight or cost for every edge is given. Kruskal’s algorithm will find the minimum spanning tree using the graph and the cost. It is the merge-tree approach. Initially, there are different trees, this algorithm will merge them by taking those edges whose cost is minimum, and form a single tree.
What is the oldest minimum spanning tree algorithm?
- algorithm. time O (E). Boruvka's algorithm is the oldest minimum spanning tree algorithm was discovered by Boruvka's in 1926, long before computers even existed. The algorithm was published as a method of constructing an efficient electricity network.
Are GPU implementations of Boruvka's algorithm more efficient than CPU implementations?
- In our comparisons, we also showed that GPU implementations of Boruvka?’s algorithm are usually more ef?cient than CPU implementations, and that the implementations we propose outperform all other tested implementations, using the same algorithm for both multi-core CPU and CUDA implementations.
