Existing tools for ARC-middleware job management provide only basic operations. The effort required for job management using these tools increases with the number of jobs to execute. Most of the existing tools also lack capabilities to manage jobs on multiple clusters. The arcControlTower (aCT) is a job management framework that can efficiently manage thousands of jobs over many clusters. However, it lacks a user interface that would enable its use as an alternative to other tools. Our goal was to extend aCT to enable the creation of various user interfaces. We achieved that by adding application programming interface (API) to aCT. Then, we have developed command line interface (CLI) using the API as this type of interface is the most commonly used among job management tools. Moreover, we have developed REST interface that enables a server setup of aCT since the web access to computing resources is becoming more and more popular. The user interface enabled us to use aCT for managing several thousands of jobs from the ATLAS experiment.
