3 ENHANCED CAPABILITY MEANS Faster More efficient More productive Easier to use New possibilities

4 GAPlotObj AND MDSplus ENHANCE DATA VISUALIZATION AND ANALYSIS CAPABILITY GAPlotObj Object-oriented library for dynamic plotting in IDL MDSplus At : a centralized repository for analyzed data Two example tools using GAPlotObj and MDSplus ReviewPlus: general 2D and 3D data viewing EFITviewer: rapid assessment of equilibrium fit from EFIT Key benefit for collaborators: site independence

5 GAPlotObj: AN OBJECT-ORIENTED LIBRARY FOR DYNAMIC PLOTTING Visualization tools at GA are written in IDL (from RSI) Rich, easy to use language Extensive, powerful interactive graphics GAPlotObj: IDL class library encapsulating dynamic plotting Written by Data Analysis Applications group and Fanning Consulting Used in many applications Not IDL s OpenGL-based Object Graphics Benefits to user Interactive plotting = rapid feedback, no change of focus Same interface in every tool

6 DYNAMIC PLOTTING WITH GAPlotObj Selected data trace Mouse cursor Zooming in Crosshairs in every plot Crosshairs follow data Five Mouse Modes 1) Select Data values Copy, delete Math 2) Zoom On Feature of interest Toggle between single and multiple plots 3) Edit Add, move, delete points in data trace 4) Cursor Mark reference points 5) Slice 2D & 3D Coupling

7 2D AND 3D PLOT INTERACTION Image plot of Te Z (m) Move crosshairs from t = 1400 to t = 3000 ms Time (ms) 3000 Time history (Z = 0 m) Te (ev) 2000 Crosshairs in time history slice plot also move Time (ms) Te(Z) profile Te (ev) t = 3000 ms Profile slice plot changes from t = 1400 ms to t = 3000 ms t = 1400 ms Z (m)

8 MDSplus SIMPLIFIES DATA ACCESS Conventional Storage MDSplus Analysis B Digitizer (PTDATA) Analysis A USER Calibrations USER Digitizer (PTDATA) Analysis A Comments Comments Geometry Calibration and Geometry Analysis B Separate interface for each data type Must know data format and file location Data and context stored separately Hard to share results One interface to many data types Only need location of data in tree Store all relevant information Remote exploration of data productive

9 MDSplus SUCCESSFULLY DEPLOYED FOR Stores analyzed data from 4700 shots so far All shots since 1998 plus most popular old shots 40 GB total file usage Currently up to 16 datasets per shot (20 MB/shot), more being added Now using Unix MDSplus Compaq DEC Alpha workstation (Tru64 Unix) with 100 GB RAID 5 Integrates more closely with Unix computing environment Upgradable path for CPU and storage Most analyzed data loaded between pulses by event-driven system Can load at any time

10 ReviewPlus: GENERAL 2D AND 3D DATA VIEWING Temperature (ev) File Edit Transform Plasma Current (MA) Plasma Current Time History Time (ms) Thomson Scattering Profile Te at t = 3000 ms 10 Debug Channel ReviewPlus on hera.gat.com Mouse mode control: Select Zoom Edit Cursor Slice Crosshairs L: Toggle sliceing M: Crosshairs Temperature (kev) EFIT Pressure Profile Electron Temperature vs. Density Density (10 19 /m 3 ) Status: ( , ) Default Shot: Update Auto update Help Data combinations Overplotting Any Y versus any X Math functions 2D and 3D coupling Signal menu and web help Automatic updating

12 MULTIPLE SITES AND SITE-INDEPENDENCE ReviewPlus and EFITviewer can run on at any site with IDL and MDSplus Better for collaborator: run anywhere to view data from anywhere else Reviewplus can access data from any site with MDSplus EFITviewer is not fully site-independent Can plot EFIT results from any site But machine-specific geometry and diagnostic overlays Can use MDSplus to make EFITviewer site-independent Store machine-specific information with data, not in code

13 MDSplus: THE KEY TO SITE-INDEPENDENT TOOLS Tools driven by structure of data in MDSplus Example: EFITviewer C Mod EFIT EFIT Results Geometry Limiter CER Chords VB Results Geometry Limiter Soft-Xray Hirex Overlay Menu Limiter CER Chords VB Overlay Menu Limiter Soft-Xray Hirex Many codes can benefit EFIT TRANSP Theory and simulation Discussions are underway between U.S. fusion sites to collaborate on tools of common interest

14 SUMMARY: GAPlotObj AND MDSplus ENHANCE COLLABORATOR ABILITY TO ANALYZE DATA GAPlotObj Interactive plotting = rapid feedback, no change of focus Unified interface in all tools MDSplus Simplified data access and storage Remote exploration of data Both used in ReviewPlus and EFITviewer Bring new capabilities to user Can run at any site with IDL and MDSplus Collaboration is the future of software in fusion community Run any code anywhere on any data from any site
