About Yabi

Yabi is a 3-tier application stack to provide users with an intuitive, easy to use, abstraction of compute and data environments. Developed at the Centre for Comparative Genomics, Yabi has been deployed across a diverse set of scientific disciplines and high performance computing environments.

Key features

Yabi has a few key features:

  • simplified web based access to High Performance Computing
  • easy tool addition and maintenance
  • handling of disparate compute and storage resouces ie. PBSPro, SGE, Torque, SSH, SFTP, Amazon S3, Swift
  • easy and powerful workflow creation environment

A brief history

The Centre for Comparative Genomics has been addressing the problem of facilitating transparent access to HPC for over a decade. As technologies have advanced we have gone through various iterations to address this issue. Now we have drawn on our experience in HPC and Internet based solutions to produce Yabi, an intuitive abstraction of compute and data environments.


The Yabi architecture consists of three main components:
  • The Client (typically a web browser or yabish)
  • The Yabi Application
  • The Yabi Backend (Yabi Resource Manager)


The client is typically a web browser, although a command line client also exists (yabish). The command line client interacts with the front end application in the same way as a web browser, that is:

  • cookies are used to maintain a user session
  • all traffic is via HTTPS
  • users are required to log in to activate a session

Yabi Application

The Yabi application is a Python web application running under Apache 2 via mod_wsgi. HTTP and HTTPS are required, although the application will insist on HTTPS and redirect any HTTP requests to HTTPS. The application runs under Apache using mod_wsgi so does not require any additional accounts, privileges or ports to be created/opened.

The Yabi application is intended to be run on an Internet facing server as it serves the HTML/CSS/Javascript application that users typically interact with as well as a REST style interface for the command line client. Naturally, it can be deployed on an internal network if access over the Internet is not desired.

Yabi Backend

The Yabi Backend Server makes use of the Celery Task Engine to queue user jobs before distribution to the appropriate execution backend via a message broker ( typically RabbitMQ but this is configurable.)

The Yabi Backend server is responsible for the communication with individual data and compute resources.
