PSCToolkit

This repository contains the various libraries that make up the Parallel Sparse Computation Toolkit (PSCToolkit) as submodules.

• PSBLAS
• PSBLAS-EXT
• AMG4PSBLAS

All the relevant information can be found at: psctoolkit.github.io. Moreover, it contains a version of the SUNDIALS library interfacing the PSCToolkit routines for linear algebra (distributed matrices and vectors), linear solvers and preconditioners.

How to get

To clone the the repository in the maintenance versions do

git clone https://github.com/psctoolkit/psctoolkit.git

or if you want to use ssh:

git clone git@github.com:psctoolkit/psctoolkit.git

To keep the development version updated with the changes in the individual repositories, use the command:

git submodule update --init --recursive

or to execute git pull inside each of the folders to synchronize to the latest version.

Warning: the various submodules point to mutually compatible versions of the library. Branch switching and pull operations could damage compatibility, especially moving into development branches. The easiest way is to download the latest stable release. This contains all versions of the packages that can be compiled together.

Docker

Each push to this repository starts building a docker image on Dockerhub. You can download the latest compiled version from a machine running Docker with the command:

docker pull psctoolkit/psctoolkit

Once the image is obtained, you can launch an interactive shell on your machine with:

docker run -it psctoolkit:latest /bin/bash

If you want to build everything on your local machine, an alternative is - once the repository has been cloned - run

cd psctoolkit
docker build - < Dockerfile

How to install

The possible installation order are:

1. PSBLAS -> PSBLAS-EXT -> AMG4PSBLAS -> SUNDIALS
2. PSBLAS -> AMG4PSBLAS

Each of the libraries contains its own installation instructions. See information on https://psctoolkit.github.io/libraries/.
