Telephone Conference 2010-10-19



This telephone conference dealt with the evaluation of the existing clients and some organizational stuff

Evaluation document

  • Should add diagrams that better depict the situation than only plain text
  • Distinction between compute and Data
    • UNICORE does not distinguish
    • ARC compute clients only support job submission and the like. Data transfer is dealt with in separate libraries.
    • gLite does distinguish, but simple data transfers client/server and server/server are supported by the compute clients
  • Add information about brokering capabilities of the clients (TODO)
  • How portable are the clients? We should have a matrix of supported platforms (TODO)
    • UNICORE, being based on Java is very portable (Windows, MacOS, Linux)
    • ARC is also very portable, can run on Windows, MacOS and all flavors of Linux
    • Most gLite components could be built manually on several platforms. ETICS seems to pose a barrier here, as it is difficult to configure for platforms other than SL 4 or SL 5.
  • Add links to client documentation, so all of us can get a better understanding of the details of each other's middleware. (TODO)
  • Chances for harmonization
    • common library for EMI proposed by Martin
      • Valid idea, but I think this is rather for communication with the EMI Execution Services, which will take time to be developed
      • Could be going a bit too far for accessing all of the middlewares
    • From the user's point of view: align interface, e.g. command line options, command names etc.
      • cf. qsub command available for many RMSs.


  • We will maintain a common todo list on the group's Wiki page
