Running an interactive grid job

The command to run a job and return it's output immediately is globus-job-run. Examples below should be self explanatory. 

[ew2193@grid ~]$ globus-job-run athena.rit.albany.edu/jobmanager /bin/hostname
athena.rit.albany.edu
[ew2193@grid ~]$ globus-job-run athena.rit.albany.edu/jobmanager-condor /bin/hostname
athena-02.rit.albany.edu


[edit]

Running a grid batch job

Batch jobs return immediately without waiting for the application to finish, you will have to retrieve the output later through other commands. If you are running long jobs you may need to create a longer proxy certificate ( man grid-proxy-init ). See example below. 

[ew2193@grid ~]$ globus-job-submit athena.rit.albany.edu/jobmanager /bin/hostname
https://athena.rit.albany.edu:15503/22313/1133556068/
... approx 1 minute time
[ew2193@grid ~]$ globus-job-get-output https://athena.rit.albany.edu:15503/22313/1133556068/
athena.rit.albany.edu

or 

[ew2193@grid ~]$ globus-job-submit athena.rit.albany.edu/jobmanager-condor /bin/hostname
https://athena.rit.albany.edu:15503/23215/1133556214/
[ew2193@grid ~]$ globus-job-get-output https://athena.rit.albany.edu:15503/23215/1133556214/
