GPU on GRID

See the required underlying steps to enable GPU job submission.

Use Case 1: Direct job submission to a CREAM service

1. Acomplished through gpu resource under JDL's CERequirements.

2. There is no GPU matchmaking: the grid user needs to know the endpoint to submit to. A basic JDL example could be:

   •     # cat test_cream.jdl
         [ 
             JobType = "Normal"; 
             Executable = "foo.sh"; 
             StdOutput="out.out"; 
             StdError="err.err"; 
             InputSandbox={"foo.sh"}; 
             OutputSandbox={"out.out", "err.err" }; 
             OutputSandboxBaseDestUri="gsiftp://localhost";
     
             CERequirements="gpu==2";
         ]

   Submit the job directly to the CREAM service with glite-job-ce-submit.

Use Case 2: Job submission through WMS
