Comment: Remote Parallel Visualization using Franklin at NERSC

...

  1. Load the mesh and mode as usual, making sure that "Read Internal Volume" is enabled.
  2. Set up an appropriate mesh view.
    1. Hide the External Surface and show the Entire Volume (click the corresponding eye icons).
    2. Set External Surface drawing style to Surface if it isn't already (might default to Outline, which appears as a wireframe box)
    3. Set the surface to display a field you are interested in (so you can know that you will orient the sampling plane correctly)
    4. Select "Entire Volume" so that text is highlighted
  3. Create the sampling filter
    1. create the filter: "Filters -> Alphabetical -> Plane Glyphs". This will show a wireframe bounding box and a red outline for the plane orientation.
    2. Position the plane where you want it. The most consistent and repeatable way to do this is to put values in for "Center" and "Normal" which specify a point in the plane and the plane's normal vector, respectively. Change "Resolution" to 100, and hit "Apply"
  4. (Optionally) Save the data
    1. Presumably, this re-sampled data is to be exported, so make sure that only the re-sample filter is active and visible in the Pipeline Browser, then
    2. "File -> Save Data", type in a file name, set "Files of Type" to be "CSV" (Comma Separated Values) which is readable by spreadsheets and Matlab. Hit "OK".
    3. For "Configure Writer", you probably don't want to Write All Time Steps. And "Field Association" should be "Points". Hit "OK". (The file should be written to the same directory from which you originally ran ParaView, unless you navigated elsewhere.)

Remote Parallel Visualization on Franklin at NERSC

Setup (one time only):

  1. Configure your ParaView Client to know about the server on Franklin at NERSC
    1. Download http://www.slac.stanford.edu/~schussma/Franklin_community.pvsc server configuration file and save a copy local to your desktop machine.
    2. Edit your copy of Franklin_community.pvsc to change the single occurrence of the word "zebra" to your Franklin login name.
    3. On your desktop machine, run paraview 3.8.1 (must be 3.8.1 to match what's on Franklin; other versions will not work)
    4. Hit the "connect" button (with the green dot).
    5. Click "Load Servers".
      1. Browse to where you saved the attached .pvsc file, select it, hit "Ok".
      2. Select "Franklin_community" in the "Choose Server" dialog, hit "Connect".
      3. The defaults should be ok. Hit "Connect".
    6. Two dialogs will pop up ("Output Messages" and "Starting Server"). When they appear, ignore them...
    7. Instead, go to the terminal on your desktop from which you originally ran ParaView, and there type in your Franklin Password.
      1. If all is well, Franklin should respond to your password with something that looks like "7049275.nid00003".
      2. You may need to wait a minute or so more until Franklin schedules your parallel server job.
    8. When the "Starting Server" dialog disappears, you have connected successfully.
  2. Configure the SLAC plugin.
    1. go to "Tools->Manage Plugins".
      1. Look in the right panel ("Local Plugins")
        1. if "SLACTools" isn't loaded, select it and hit "Load Selected".
        2. Click the "+" next to it, and make sure "Auto Load" is checked.
      2. Look in the left panel ("Remote Plugins")
        1. Make sure "SLACTools" is loaded and set to Auto Load as well.
      3. Hit "Close", and quit ParaView. Setup is complete.

Running Paraview on Franklin (general case):

  1. On your desktop machine, run paraview 3.8.1 (must be 3.8.1 to match what's on Franklin; other versions will not work)
  2. Hit the "connect" button (with the green dot).
  3. Select "Franklin_community" in the "Choose Server" dialog, hit "Connect".
  4. The defaults should be ok. Hit "Connect".
    1. Two dialogs will pop up ("Output Messages" and "Starting Server"). When they appear, ignore them...
    2. Instead, go to the terminal on your desktop from which you originally ran ParaView, and there type in your Franklin Password.
    3. If all is well, Franklin should respond to your password with something that looks like "7049275.nid00003".
    4. You may need to wait a minute or so more until Franklin schedules your parallel server job.
    5. When the "Starting Server" dialog disappears, you have connected successfully.
