Supported tags and respective Dockerfile links

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

Usage

In this usage, users can select the corresponding {Tag} and container startup options based on their requirements.

• Pull the openeuler/openlb image from docker

  bash
  docker pull openeuler/openlb:{Tag}
  

• Start a openlb instance

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

• Running Test Cases

  All test cases can be compiled by running the make samples command. For details about how to execute an independent test case, for example, cylinder2d, see Non-parallel Computing and Parallel Computing.

  • Non-parallel Computing Procedure

    1. Go to the directory where the test case is stored.

       bash
       cd examples/laminar/cylinder2d
       

    2. Compile the test case.

       bash
       make
       

    3. Run the program to perform the computing.

       bash
       ./cylinder2d
       

       The generated VTK and gnuplot results are stored in the /tmp directory.

  • Parallel Computing Procedure

    1. Go to the directory where the test case is stored.

       bash
       cd examples/laminar/cylinder2d
       

    2. Compile the test case.

       bash
       make
       

    3. Run the program to perform the computing. The following uses -np=64 and OMP_NUM_THREADS=1 as an example.

       bash
       mpirun –allow-run-as-root –np 64 –x OMP_NUM_THREADS=1 ./cylinder2d
       

       The generated VTK and gnuplot results are stored in the /tmp directory.
