1. ElVis Tutorial Eliot Feibush http://w3.pppl.gov/elvis

2. ElVis Display and interaction – Scientific Data. Applications send data to ElVis for display. Enhanced graphics with minor changes to existing programs. ElVis interfaces: –Subroutine programming (API – data in) –Graphical, interactive (GUI) Vector PostScript output.

3. Example Plots

4. Fusion Grid Monitor - TRANSP Inputs

5. Data Monitoring - TRANSP Output

6. NSTX TF Monitor

7. Send Data to ElVis RPLOT ElVis Inter-Process Communication Data Socket App 2App 3... ElVis library Petrel002 myWindowsPC ElVis Server/Host machine

8. Socket Connection Socket – data stream between 2 programs –Can be on different computers. ElVis Title Bar has port number & hostname ElVis hostname: red-tst ElVis Port Number: 7654 (OS resource) red-tst.pppl.gov

9. 1. Run ElVis on Windows Browse to: w3.pppl.gov/elvis Click on: Run ElVis Runs ElVis program on PC. red-tst.pppl.gov
