The JSUB task submission and management software

Abstract

Abstract In near future, new high energy physics experiments with challenging data volume are coming into operations or are planned in IHEP, China. A DIRAC-based distributed computing system is being enabled to process the huge amount of data to be obtained in these experiments. To encourage better utilization of computing resources, it’s essential to give users handy tools that saves them from troubles of mastering various technical details of distributed computing and let them have comfortable control over their tasks. In this conference, we present the design and development of a extensible task submission and management system called JSUB, which provides users from different experiments with consistent solutions of managing massive jobs. JSUB covers functionalities including user interface, task creation and submission, run-time workflow control, task monitoring and management. Major features of this software include friendliness with extensions into different user scenarios, flexible task setting, and parametric job submission. Currently, the JSUB software has been developed and put into use for JUNO and CEPC experiments. The software is also highly extensible to other HEP experiments. The designs and techniques could be interesting to other experiments which also use DIRAC as workload management system. The software has only been previously reported inside JUNO collaboration, and this is the first time to be presented to a wider audience.
