Remote backend - submit jobs to a Remote pool.

   The remote backend works as an SSH tunnel to a remote site
   where a ganga session is opened and the job submitted there
   using the specified remote_backend. It is (in theory!)
   transparent to the user and should allow submission of any jobs
   to any backends that are already possible in Ganga.

   NOTE: Due to the file transfers required, there can be some slow
   down during submission and monitoring

   
   E.g. 1 - Hello World example submitted to local backend:

   j = Job(application=Executable(exe='/bin/echo',args=['Hello World']), backend="Remote")
   j.backend.host = "bluebear.bham.ac.uk"                  # Host name
   j.backend.username = "slatermw"                         # User name
   j.backend.ganga_cmd = "/bb/projects/Ganga/runGanga"     # Ganga Command line on remote site
   j.backend.ganga_dir = "/bb/phy/slatermw/gangadir/remote_jobs"  # Where to store the jobs
   j.backend.remote_backend = Local()
   j.submit()


   E.g. 2 - Root example submitted to PBS backend:
   
   r = Root()
   r.version = '5.14.00'
   r.script = 'gengaus.C'
   
   j = Job(application=r,backend="Remote")
   j.backend.host = "bluebear.bham.ac.uk"
   j.backend.username = "slatermw"
   j.backend.ganga_cmd = "/bb/projects/Ganga/runGanga"
   j.backend.ganga_dir = "/bb/phy/slatermw/gangadir/remote_jobs"
   j.outputsandbox = ['gaus.txt']
   j.backend.remote_backend = PBS()
   j.submit()


   E.g. 3 - Athena example submitted to LCG backend
   NOTE: you don't need a grid certificate (or UI) available on the local machine,
   just the remote machine

   j = Job()
   j.name='Ex3_2_1'
   j.application=Athena()
   j.application.prepare(athena_compile=False)
   j.application.option_file='/disk/f8b/home/mws/athena/testarea/13.0.40/PhysicsAnalysis/AnalysisCommon/UserAnalysis/run/AthExHelloWorld_jobOptions.py'

   j.backend = Remote()
   j.backend.host = "bluebear.bham.ac.uk"
   j.backend.username = "slatermw"
   j.backend.ganga_cmd = "/bb/projects/Ganga/runGanga"
   j.backend.ganga_dir = "/bb/phy/slatermw/gangadir/remote_jobs"   
   j.backend.environment = {'ATLAS_VERSION' : '13.0.40'}     # Additional environment variables
   j.backend.remote_backend = LCG()
   j.backend.remote_backend.CE = 'epgce2.ph.bham.ac.uk:2119/jobmanager-lcgpbs-short'

   j.submit()

   E.g. 4 - Hello World submitted at CERN on LSF using atlas startup

   j = Job()
   j.backend = Remote()
   j.backend.host = "lxplus.cern.ch"
   j.backend.username = "mslater"
   j.backend.ganga_cmd = "ganga"
   j.backend.ganga_dir = "/afs/cern.ch/user/m/mslater/gangadir/remote_jobs"
   j.backend.pre_script = ['source /afs/cern.ch/sw/ganga/install/etc/setup-atlas.csh'] # source the atlas setup script before running ganga
   j.backend.remote_backend = LSF()
   j.submit()
