PROOF

PROOF (PRoduction On-ramp for Optimization and Feasibility) is a user-friendly tool designed for managing and executing WDL (Workflow Description Language) workflows using the Cromwell workflow manager, configured to run on the Fred Hutch cluster. PROOF allows users to:

• Automate all the backend configurations necessary to run your workflows instantly.

• Validate, troubleshoot, assess performance, and run their workflows all under one roof.

• Refine their workflows before potential transitions to cloud-based infrastructures, providing a ‘proofing’ resource of sorts.

Release Notes

February 2024

What’s New!

• PROOF has now grouped together all the components for setting up and configuring your database and Cromwell server so you don’t have to manually configure each part!
• You can interact with PROOF in two improved ways when running your workflows:
  • PROOF Shiny App - an easy to use interface for accessing and configuring workflows to run on our cluster
  • Through the R clients proofr and rcromwell - combined these allow you to run WDL workflows on PROOF from your R console
• We’ve made some enhancements to the way you use PROOF including:
  • Each user must login with your Fred Hutch credentials so that no one else can access or use your Cromwell server session
  • Each user can only run one Cromwell server at a time so that you don’t lose track of your workflow sessions
