About

Distributed systems pose many difficult problems to researchers. Due to their large-scale complexity, their numerous constituents (e.g., computing nodes, network links) tend to fail in unpredictable ways. This particular fragility of experiment execution threatens reproducibility, often considered to be a foundation of experimental science.

XPFlow is a new approach to description and execution of experiments involving large-scale computer installations. The main idea consists in describing the experiment as workflow and using achievements of Business Workflow Management to reliably and efficiently execute it. Moreover, to facilitate the design process, the framework provides abstractions that hide unnecessary complexity from the user.

Getting started

Install XPFlow:

# gem install xpflow --pre

Create a script with description of your experiment:

# file: basic.rb
process :main do
    log "Hello World"
end

And launch it:

$ xpflow helloword.rb

For more inforamtions, please see the tutorial or the documentation.

The latest version of XPFlow is 0.1c.
