Running RPLOT Within ElVis -- A Web Service
If you are running on a computer outside the PPL firewall then you must
authenticate with the PPL firewall to run RPLOT.
You must also have a valid FusionGrid credential because rplot is run
through GLOBUS on the PPL cluster.
On the toolbar, go to Desktop --> rplot ...
This brings up a dialog window for a FusionGrid
Credential. Enter your FusionGrid user name and passphrase.
Click Sign On. This will check your credential on the Credential
Server to determine if you can run RPLOT at PPL. If it succeeds
then the text areas will get a green background and information about
your credential and proxy will be shown. If it fails then the
background will turn red. If you are running ElVis as an
application then it will fill in the
User Name with your log in account. If this is different than
your
FusionGrid user name then enter your FusionGrid user name.
After you sign on the rplot window will be displayed:
This window is the client side of an rplot session running on the PPL
cluster. Text output from rplot is shown in the panel on the
left. Graphs are drawn in the panel on the right. Enter
commands in the command line at the bottom left. A copy of rplot
is running with your pshare user ID, such
as pshr0003. The current working directory is
/u/pshrNNNN/rplot. You can enter rplot commands to access runs
stored in files or in MDSplus. You can run rplot scripts stored
in command files.
Be sure to exit rplot before quiting
ElVis. Quit out of all menu levels or enter *A or *A! for
immediate exit. A message will be displayed in the command line
area when rplot exits. Be sure to exit rplot to avoid leaving
copies of the program running on the cluster.
Each command you enter is sent to the rplot program. It
returns lines of text and draws graphs when they are complete.
You can explore the graphs using the interactive features in
ElVis. Each graph is added to the window which will scroll.
Initially one column of graphs is displayed. The Layout page in
the Graph Editor has controls for changing the number of rows and
columns of graphs.
Click in the command line or the text area above it to regain typing
focus for entering commands.
