ketrew

A Workflow Engine for Computational Experiments
Description

Ketrew is:

  1. An OCaml library providing an EDSL API to define complex and convoluted workflows (interdependent steps/programs using a lot of data, with many parameter variations, running on different hosts with various schedulers).
  2. A client-server application to interact with these workflows. The engine at heart of the server takes care of orchestrating workflows, and keeps track of everything that succeeds, fails, or gets lost. The clients interact with an API and with two user-interfaces: a terminal-app and a WebUI.
