The PyCOMPSs CLI (pycompss) provides a standalone tool to use PyCOMPSs interactively within docker environments, local machines and remote clusters. This tool has been implemented on top of PyCOMPSs programming model, and it is being developed by the Workflows and Distributed Computing group of the Barcelona Supercomputing Center.
There are two ways in which you can get started with PyCOMPSs. You can perform a local installation by installing the pycompss package, or you can use it through our ready-to-use docker image thorugh this pycompss-cli tool.
python3 -m pip install pycompss-cli
This should add the pycompss-cli executables (pycompss, compss and dislib) to your path. They can be used indiferently.
Warning: The user executable path may not be automatically exported into the PATH environment variable. So, take this into account if installed with the --user flag, since the pycompss|compss command will be unreachable until the path is exported into PATH.
For creating docker environments pycompss-cli currently requires:
docker >= 17.12.0-ce
pycompss-cli requires docker 17.12.0-ce or greater.
Follow these instructions
Be aware that for some distros the docker package has been renamed from docker to docker-ce. Make sure you install the new package.
Add user to docker group to run pycompss as a non-root user.
Check that docker is correctly installed
docker --version docker ps # this should be empty as no docker processes are yet running.
python3 -m pip install docker
