Web Portals for High-performance Computing

Abstract

This article addresses web interfaces for High-performance Computing (HPC) simulation software. First, it presents a brief history, starting in the 1990s with Java applets, of web interfaces used for accessing and making best possible use of remote HPC resources. It introduces HPC web-based portal use cases. Then it identifies and discusses the key features, among functional and non-functional requirements, that characterize such portals. A brief state of the art is then presented. The design and development of Bull extreme factory Computing Studio v3 (XCS3) is chosen as a common thread for showing how the identified key features can all be implemented in one software: multi-tenancy, multi-scheduler compatibility, complete control through an HTTP RESTful API, customizable user interface with Responsive Web Design, HPC application template framework, remote visualization, and access through the Authentication, Authorization, and Accounting security framework with the Role-Based Access Control permission model. Non-functional requirements (security, usability, performance, reliability) are discussed, and the article concludes by giving perspective for future work.
