GumTree Project

• GumTree is a scientific workbench that manages
  the complete experiment lifecycle for users
• Integrated Scientific Experiment Environment
• Instrument Control Data Acquisition
• Online and Offline Data Analysis
• Electronic Laboratory Notebook Report (OLE,
  BIRT)
• proposed Collaborative environment for
  multi-national experiment (ECF)

GumTree Vista

• GumTree has been built on a new architecture,
  with codename Vista

GumTree RCP GumTree RAP
Swing Based Diagnostic Tools
J2EE Web Interface
Instrument Model Server

GumTree Vista

• Motivation
• Data analysis team wants to access experiment
  data via instrument component
• Web interface for status monitoring
• Model / data flow driven development
• GumTree RCP remains its role as the integrated
  scientific workbench
• First prototype will be available on Jul 06

12
New Features

• What can GumTree Vista offer
• Simplified API for adapting to other control
  system
• Stronger security in new layered architecture
• Validation of user request based on various
  sources (eg current instrument status, database,
  etc)
• Multi-clients connectivity (independent of
  technology choice)

13
RCP Control System

• Controlling instrument via instrument model
  (JaveBean data structure)
• Instrument model server can produces a model
  driven data set
• Instrument model server can be adapted to other
  control system

RCP Visualisation

• Visualisation component will be split into two
  levels
• General purpose SWT widget with no dependency on
  the rest of GumTree system
• Extension of GumTree (allows binding with
  internal GumTree data for display)

SWT VIS
SWT/OpenGL
NeXus VIS
GumTree VIS
Can be used by other SWT/RCP applications
16
RCP Data

• Internal data format has been chosen to Extended
  NeXus format
• It describes the whole instrument model
• Strong linking to control system, experiment
  setup (via wizard), monitoring, etc
• NeXus format can be transformed to other data
  format via XSLT (heavy commitment by ANSTOs data
  analysis team)
• Another possible GumTree internal data
  representation EMF

17
Data Analysis
Run algorithm remotely by RMI, TANGO, Web Service
(GRID), or PTP API??

NOMAD

• Developed by Institut Laue-Langevin (France)
• To be deployed on 11 neutron beam instruments in
  June
• Based on SWT and OpenGL
• User interface components are generated by XML
  definition (like XSWT)
• Has a cool way to perform experiment!
• Collaboration? Well, its not open source.

22
FABLE

• Joint collaboration between ESRF (France) and
  Risø Institute (Denmark)
• Scientific workbench for crystallography data
  analysis with synchrotron data
• Can be extended to acquire data from the
  synchrotron beamline.

23
Collaboration

• Share development experience
• Discussion
• Recommendations
• Do not duplicate our efforts
• Reusable code / plugin
• Manage existing open source projects

24
Possible Collaboration Methods

• Scientific Plugin Library
• Every facility requires different system
  architecture
• Sharing codes in plugin level is more realistic
• SciForge.net??
• Eclipse based scientific community
• A community under Eclipse Foundation
• Benefits website space, mailing list, bugzilla,
  newsgroup, gaining publicity in mainstream IT
  industry
• Drawback management is time consuming

25
Case Study onEclipse Community Model

• A dedicated scientific eclipse project
• Example Parallel Tools Platform (PTP) Project
• Managing individual sub-projects under a
  community
• Example Generative Model Transformer (GMT)
  Project
• Promotion of Eclipse technology with almost no
  software artefacts
• Example Eclipse Community Education Project
  (ECESIS)

26
Case Study onEclipse Community Model

• Foundation Member Working Groups
• Example Japan Working Group
• Should we call ourselves Scientific Woking
  Group??
• Initial subproject under existing Eclipse
  Technology Project
• Example NO
• Greg Watson (Los Alamos Cluster computing team)
  from PTP has offered his help

27
Conclusion

• Increasing adoption of Eclipse Technology creates
  opportunity for us to share codes
• Question Are we on the same road?
