Setting up your own gateway to the grid is beyond the scope of this write up. It involves installing the Virtual Data Toolkit (VDT) , you'll need a host certificate for the gateway machine etc. etc. For an administration guide see the Fermi Grid web page.
Examples
Setting up the Environment
To set up the environment and to get the necessary grid Proxy log into ILCSIM and issue the following commands:The SLIC test job below actually tries to store the output in mass storage using the grid srmcp file transfer tool. But It's probably easier to transfer the output via condor. An example will be provided once it has been tested.

Submitting the first Job
Now you should be all setu to submit a job:
...
setup to submit a first trivial test job just to make sure that everything is working. Just cut and paste the following lines into your terminal window. This will submit a grid job which starts 5 separate processes. The processes will not do anything exciting but execute sleep for 10 seconds before they terminate. Since not output is created the sleep_grid.out.$(Cluster).$(Process) and sleep_grid.err.$(Cluster).$(Process) should be empty.
(Note!: $(Cluster) represents the jobnumber and $(Process) represents the (5) process numbers)
The condor log files are: sleep_grid.log.\$(Cluster).\$(Process)
