Workflow PortletPurpose
Workflow-oriented computational Grid applicationsSupports the creation and execution of workflow-based Grid applications in a Job Description Language (JDL)
Grid Services supported by the portletGRAM jobGridFTP
Grid Portal – Job Submission PortletGrid Portal – Job Submission PortletJava programs for job submissionThe components of Job Submission Portlet:
Interactive Mode: displays the output in real timeHybrid Mode: writes into a file and also displays output in real timeBatch Mode: writes into a file and then GridFTP to local machine
