PoC Induction 19-April
Use Case: fMRI requirements (short)
• File system requirements: Grid FTP access (GFTP) Secure FTP access (SFTP) Storage Resource Broker (SRB) Meta Data management
• Grid Services: Reliable File Transfer Job Submission/Monitoring
• Authentication/Account management: Centralized account management Simple authentication mechanism

PoC Induction 19-April
Use case: Existing problems Tools
• Lots of different tools for different protocols Graphical SRB client (inQ) only for windows Web tools SRB interface clumsy Command line tools (S-commands) not user
friendly for end user (Medical Scientists). No integration with other (Grid) file systems like Grid-FTP or Secure FTP
• Need extensible File management tool default SRB/Grid tools are not 'extensible‘
• Need embedded content viewer also Plugins/Mimetype viewers for application data
PoC Induction 19-April
Design: Single GUI for 'The Grid'
Single access point to ‘The Grid’
Virtual metacomputer
All tools (seemingly) integrated
into one ‘meta’ or ‘virtual’
computer
No need for extra software
(Only java 1.5 needed)
Same look and feel for both
windows and linux (but
customizable)
