These are set to the base of your Globus installation and GridWay installation. In GT 4.2, GridWay is installed in the same place as Globus, so you can set both of these environment variables to the same location. text/html 2015-03-09T12:58:16+0000 Anonymous (anonymous@undisclosed.example.com) https://gridway.ucm.es/doku.php?id=documentation:release_5.5:cli&rev=1425905896&do=diff Command Line Interface 5.5 gwsubmit Name gwsubmit — job submission utility for the GridWay system Synopsis Description Submit a job or an array job (if the number of tasks is defined) to gwd Command options * -h Prints help. * -t <template> text/html 2015-03-09T12:58:16+0000 Anonymous (anonymous@undisclosed.example.com) https://gridway.ucm.es/doku.php?id=documentation:release_5.5:dg&rev=1425905896&do=diff Developer's Guide 5.5 Programming Model One of the most important aspects of Grid Computing is its potential ability to execute distributed communicating jobs. The Distributed Resource Management Application API (DRMAA) specification constitutes a homogeneous interface to different Distributed Resource Management Systems (DRMS) to handle job submission, monitoring and control, and retrieval of finished job status. text/html 2015-03-09T12:58:16+0000 Anonymous (anonymous@undisclosed.example.com) https://gridway.ucm.es/doku.php?id=documentation:release_5.5:dms&rev=1425905896&do=diff Dispatch manager Scheduler 5.5 In order to decouple the scheduling process, GridWay uses a Scheduler module to schedule jobs.

Using scripting languages makes this way of getting information unfeasible. For example python strings are immutable so it is not possible to fill an empty string with the information needed from the extension. The way the functions are called are the same as Perl and Python SGE DRMAA bindings, reference variables are omitted and what functions return is an arr… text/html 2015-03-09T12:58:16+0000 Anonymous (anonymous@undisclosed.example.com) https://gridway.ucm.es/doku.php?id=documentation:release_5.5:ia&rev=1425905896&do=diff Internal Architecture 5.5 Figure 1.Components of the GridWay Meta-scheduler.

Each job is given a numerical identifier, analogous to the PID of a process. This value is called the Job identifier, JID for short. If the job belongs to an array job, it will also have an array identifier, AID for short. A job index within an array is called the task identifier, TID for short.
