1. Remote Access of Instruments and Data at OPAL
Ladies and Gentlemen, welcome you all to this talk.
In this talk I’ll introduce you our latest
Nick Hauser (ANSTO) - presenter

2. Requirements Remote access to instruments Remote access to data
Status
Control
Remote access to data
Remote access to data analysis

3. Requirements Remote access to instruments
Status
Control
No. 1 requirement is for instrument scientist to fix problems remotely
Roles and Tokens supported by instrument server
Spy
User
Expert

4. GumTree supports the 3 remote access requirements
During this talk, I’ll be presenting the latest development of our Graphical User Interface project, called GumTree, for the Neutron Beam Instrument Project at ANSTO.
What we are working on now is a Java based Graphical User Interface called GumTree
Our mission is to plant GumTree for our beamline users

5. Software architecture
Control / Status
Data Visualization
Data Analysis
GUI
Client
Server
SIC Server
Motors
Detectors
Ancillaries
What we are doing now in ANSTO is to develop a common interface across different instrument
Basic Server-Client Architecture
Sequencer from PSI
Design Goals:
Client/server model supports remote access
User must authenticate on network
Going to use ‘standard’ authentication methods

6. Software architecture
Embedded data analysis support
Support various data formats
Use the widget set of your choice
Integrate with your visualization package
This philosophy fit perfectly into the Grand Unified Model
GUM – Grad Unified Model
Flexible approach
This concept fit perfectly into the GUM theory for the scientific experiment
GumTree is the key for GUM
Adaptable to different control systems
Grand Unified Model

7. Network architecture

8. Network architecture - vLAN

9. Network Security Cybertrust security assessment
Preliminary “unclassified” status
Allows for flexible solutions
DSD data diode to RCMS
User computers only connected to Guest Network
Guest Network connected via fibre to Instrument Network
Proposed use of standalone Knoppix computer for checking virus versions. Working successfully at NIST

10. Requirements Remote access to instruments Remote access to data
Status
Control
Remote access to data
Remote access to data analysis
Data policy
Use of offsite data silos for ‘aged’ data

11. Requirements Remote access to instruments Remote access to data
Status
Control
Remote access to data
Remote access to data analysis
Licensing issues
GRID enabled data analysis

12. OPAL & GRID Distributed data analysis DANSE
Member of the ARC Molecular and Materials Structure Network
Member of GrangeNet grant
Data offsite – data policy
Take data from offsite – e.g Synchrotron to ANSTO
Access to compute power – APAC
ANSTO currently not a player in compute power – data provider

13. a
….and we want to use it

14. OPAL & AARNet ANSTO has agreed to install a fibre tail into aarnet3
Negotiation with AARNet over liability issues is proceeding

15. Eclipse Rich Client Platform
Application Framework for making FAT client
Allows data analysis functionality to be in the client
Open Services Gateway Initiative (OSGi)
Originally used as a middle layer for service delivery for embedded device
Eclipse use subset of this

16. Summary Telepresence by low bandwidth webcams
Audio presence via Skype or phone line
Standard network authentication
Local access control list
Instrument scientist remote access to instrument
Trained and certified user remote access – possibly
Instrument status via web server
