Notes on getting fusiongrid access to pull TRANSP data off PPPL servers
at GA machines

-L. Peterson 09/01/09

1. Get fusion grid access for TRANSP data:

    - go to https://cert.fusiongrid.org/CertReqForm.html
        - Fill out request, ask for "TRANSP Execute" permissions in the
          "Comments" section
        - D. McCune is the arbiter of TRANSP, but you should contact him about
          being your sponsor (dmccune@pppl.gov)
    - wait for confirmation email
    - your user id for fusion grid is my_fusion_grid_user_id. Remember it.

2. Add the following lines to your .login file 
   (modify syntax and dot file to suit your shell, as this assumes c-like). The
   only changes you need to make to this are in the first block to have your
   user id

# Fusiongrid user id
setenv FUSION_GRID_USER my_fusion_grid_user_id

# Setup TRANSP et al only if on GA Linux Machine
if ( `/bin/uname` == 'Linux' ) then
    echo "Setting up MDS+ / TRANSP on GA Linux Machine"

    # For TRANSP / trxpl
    setenv MDS_TRANSP_SERVER _transpgrid.pppl.gov
    
    # Globus and MDS+ for fusiongrid server interaction
    setenv GRID_LOCATION /f/mdsplus/grid/linux
    setenv GLOBUS_LOCATION $GRID_LOCATION/globus
    source $GLOBUS_LOCATION/etc/globus-user-env.csh
    setenv MDSPLUS $GRID_LOCATION/mdsplus
    setenv LD_LIBRARY_PATH $GLOBUS_LOCATION/lib:$MDSPLUS/lib:${LD_LIBRARY_PATH}:/d/linux/lib

    # Setup TRANSP paths
    source /c/transp/etc/transp_setup-xshare.csh

    # Renew Fusion Grid Certificate for TRANSP access
    # Only if shell is interactive and only if certificate is old
    setenv FUSIONGRID_ACCESS_ARGS "--username=$FUSION_GRID_USER"
    echo "Renewing Fusion Grid Certificate for user $FUSION_GRID_USER"
    source $TRANSP_LOCATION/fusiongrid_access.csh
endif

3. Add the following lines to your .cshrc:

# Renew Fusion Grid Access
if ($?TRANSP_LOCATION) then
    source $TRANSP_LOCATION/fusiongrid_proxypath.csh
endif


4. Try it out:
    - log on to a LINUX machine at GA (eos, delphi, etc) NOT hydra
        - remote users will have to first ssh to hydra, 
          then from hydra to eos, etc
    - type the following commands:
        - rplot
        - t
        - y
        - nstx.07
        - q
        - 124901A02
    - if those connect properly and you see it doing stuff, congrats!
      you have access to all the data in the fusiongrid tree

5. General notes:
    - the scripts will dial into the fusiongrid server and renew your
      certificate if it is too old
    - for JET data, you must fill out a special request
        - see the fusiongrid site for more info
