Parallel Summation using MPI in Python with mpi4py

Parallel Summation using MPI in Python with mpi4py

Comments 113 Comments

Parallel summation involves distributing the task of summing a large set of numbers across multiple processors or computing nodes, enabling simultaneous computation and aggregation of partial results. Each processor handles a portion of the data, performs local summation, and then communicates its partial sum to a designated root processor. The root processor collects and combines these partial sums to compute the global sum, thereby leveraging parallelism to accelerate the computation process and efficiently handle large-scale data sets. In this tutorial,…
