⁠AMG | openEuler

AMG is a parallel algebraic multigrid solver for linear systems arising from problems on unstructured grids. The driver provided with AMG builds linear systems for various 3-dimensional problems. AMG is written in ISO-C. It is an SPMD code which uses MPI and OpenMP threading within MPI tasks. Parallelism is achieved by data decomposition. The driver provided with AMG achieves this decomposition by simply subdividing the grid into logical P x Q x R (in 3D) chunks of equal size.

⁠Supported tags and respective Dockerfile links

The tag of each AMG docker image is consist of the version of AMG and the version of basic image. The details are as follows

⁠Usage

Run the AMG benchmark (default, single process):

docker run --rm openeuler/amg:{Tag}

Run with MPI (4 processes):

docker run --rm openeuler/amg:{Tag} mpirun --allow-run-as-root -np 4 amg

Run with custom problem size:

docker run --rm openeuler/amg:{Tag} mpirun --allow-run-as-root -np 4 amg -problem 1 -n 100 100 100 -P 2 2 1

Enter the container:

docker run -it --rm openeuler/amg:{Tag} /bin/bash
