英文摘要：

A Portlet-based High-Performance Computing Portal（HPCP） is proposed. HPCP is an easy-to-use, general, customizable and secure Web application for job management, supporting several operations such as job submission, states inquiries, job termination, directory listing of job and viewing of the file in real-time, file download. Theoretical analysis and test show that HPCP is user-friendly, interactive as desktop applications program, and has good scalability and security.
