An Implementation of Interactive Jobs Submission for Grid Computing Portals

The Globus Toolkit has been widely used as middleware in Grid computing environments. Java CoG, Web Service and Portlet help to build Grid computing portals easily and productively. Many Grid Portals can provide a customizable interface allowing scientists and researchers to perform Grid operations such as remote submission of their own programs, staging input and ouput files, and querying resources and queues information. However, the Globus Toolkit does not support interactive jobs submission, nor is there an interactive extension for Grid computing portals. In this paper, a Grid Security Infrastructure (GSI) enabled Java SSH client is introduced and implemented as a novel way to submit interactive jobs to the computing resources in ScGrid, which is a scientific computing environment provided by the Supercomputing Center, Computer Network Information Center, Chinese Academy of Sciences (SCCAS).
