Condor

Condor: Making best use of the computers in the teaching labs

Introduction

The Condor Project enables us to run batch jobs on the desktop computers around the department, that would otherwise be standing idle. Condor is particularly useful for high 'throughput' computing, such as an ensemble of independent model simulations, used to evaluate explore parameter-space.

Basic commands

Our 'submission host' is condor.ggy.bris.ac.uk. If you login to that machine, you can review the status of all the machines in the 'condor pool' using the command condor_status:
