I initially gave examples on how to distribute an application over the Grid using the Sun Grid Engine commands (e.g., qsub). An other option is to use the Distributed Resource Management Application API (DRMAA) which provide options to submit jobs directly from within a program. A sample code looks like in Java:

         // Submit jobs to run 
         for (int i = 0; i < 50; i++) {
           System.out.println("Creating Remote Command: " + i);
           jt[i] = session.createJobTemplate();
           jt[i].setRemoteCommand(exec);
           ids[i] = session.runJob(jt[i]);
         }

A full example is provided on the Developer Network site by Fay Salwen, one of our Grid experts.
