Integrating SCOPE with ElVis

Integrating SCOPE with ElVis

Projects

• Added the ElVis API to Scope so that Scope can
  send its data to ElVis.
• Created a post processor for reducing the size of
  netCDF input and output files, used by the Full
  Wave Reflectometer simulation.

Scope

• Scope is a 14 year old C program for displaying
  signal data from experiments (such as NSTX).
• Developed by Tom Fredian at MIT, it contains
  custom widgets and encapsulates the X-window
  event methodology.
• It is connected to the MDSplus database.
• Registers and listens for events.

4
ElVis

• ElVis can display more than one shot at a time.
• It can copy and paste signals from one graph into
  another.
• ElVis is written in Java, making it portable. It
  can be run from a browser.

5
Goal

• Add display capabilities to Scope.
• Make minimal changes to the Scope source code.
• Scope already listens for events and extracts the
  data from the MDSplus database, now ElVis can use
  them.

New Code

• Added two lines to the existing Scope code.
• ElvisConnect(row, column, xData, yData )
• Wrote a new file containing only one subroutine
  that receives the data from scope and calls the
  ElVis subroutines.
