Open Composer: A Web-Based Application for Generating and Managing Batch Jobs on HPC Clusters

Workshop: HUST-25: 12th International Workshop on HPC User Support Tools

Authors: Masahiro Nakao and Keiji Yamamoto (RIKEN Center for Computational Science (R-CCS))

Abstract: Submitting batch jobs on HPC clusters usually requires familiarity with Linux commands and job schedulers, posing a significant learning barrier for beginners. To address this issue, we have developed Open Composer, a web-based application that helps users generate and manage batch jobs on HPC clusters. Open Composer automatically generates shell scripts using web forms defined for each application while also providing a real-time preview of the generated shell scripts and allowing direct editing. This feature helps reduce both the learning curve and the risk of syntax errors while maintaining flexibility in script writing. Open Composer provides a unified interface for job submission and status monitoring, and supports reusable job parameters, dynamic form widgets, and preprocessing steps. By enhancing usability and accessibility, Open Composer aims to make HPC resources more approachable for both novice and experienced users.
