Presentation Transcript

  1. Remote Access of Instruments and Data at OPAL Nick Hauser (ANSTO) - presenter

  2. Requirements • Remote access to instruments • 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 Neutron Guide Hall @ OPAL

  5. GUI Control / Status Data Visualization Data Analysis Software architecture Design Goals: • Client/server model supports remote access • User must authenticate on network • Going to use ‘standard’ authentication methods Client Server SIC Server Motors Detectors Ancillaries

  6. Software architecture Embedded data analysis support Support various data formats Use the widget set of your choice Integrate with your visualization package 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 • 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 • 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 • Rich Client Platform • Application Framework for making FAT client • Allows data analysis functionality to be in the client

  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
