wr is a workflow runner. You use it to run the commands in your workflow easily, automatically, reliably, with repeatability, and while making optimal use of your available computing resources.

wr is implemented as a polling-free in-memory job queue with an on-disk acid transactional embedded database, written in go.

Its main benefits over other software workflow management systems are its very low latency and overhead, its high performance at scale, its real-time status updates with a view on all your workflows on one screen, its permanent searchable history of all the commands you have ever run, and its "live" dependencies enabling easy automation of on-going projects.

Furthermore, wr has best-in-class support for OpenStack, providing incredibly easy deployment and auto-scaling without you having to know anything about OpenStack. For use in clouds such as AWS, GCP and others, wr also has the built-in ability to self-deploy to any Kubernetes cluster. And it has built-in support for mounting S3-like object stores, providing an easy way of running commands against remote files whilst enjoying high performance.

Alternatively, build it yourself (see go.mod for the minimum version of go required):

    git clone https://github.com/VertebrateResequencing/wr.git
    cd wr
    make

The wr executable should now be in $HOME/go/bin.

Complete usage information is available using the -h option to wr and its sub-commands.
