Job Submission Description Language is an extensible XML specification from the Global Grid Forum for the description of simple tasks to non-interactive computer execution systems. Currently at version 1.0 (released November 7, 2005), the specification focuses on the description of computational task submissions to traditional high-performance computer systems like batch schedulers.

Description

JSDL describes the submission aspects of a job, and does not attempt to describe the state of running or historic jobs. Instead, JSDL includes descriptions of:

• Job name, description
• Resource requirements that computers must have to be eligible for scheduling, such as total RAM available, total swap available, CPU clock speed, number of CPUs, Operating System, etc.
• Execution limits, such as the maximum amount of CPU time, wallclock time, or memory that can be consumed.
• File staging, or the transferring of files before or after execution.
• Command to execute, including its command-line arguments, environment variables to define, stdin/stdout/stderr redirection, etc.

It has been suggested that Maintenance OS be merged into this article or section. ...

Software support

The following software is known to currently support JSDL:

• GridWay meta scheduler[1]
• UNICORE 6

GridWay is an open source meta-scheduling technology that enables large-scale, secure, reliable and efficient sharing of computing resources (clusters, computing farms, servers, supercomputers. ... UNICORE (UNiform Interface to COmputing REsources) is a Grid computing technology that provides seamless, secure, and intuitive access to distributed Grid resources such as supercomputers or cluster systems and information stored in databases. ...
