GT 4.1.3 GRAM4: User's Guide

Introduction

GRAM services provide secure job submission to many types of job schedulers for users who have the right to access a job hosting resource in a Grid environment. The existence of a valid proxy is in fact required for job submission. All GRAM job submission options are supported transparently through the embedded request document input. In fact, the job startup is done by submitting a client-side provided job description to the GRAM services. This submission can be made by end-users with the GRAM command-line tools.

Jobs can be described in two different job description languages: the original language defined by WS-GRAM (JDD) or in JSDL. That's why there are separate sections for the usage scenarios.
