HPC -using SOA programming model RRS feed

  • Question

  • I have read the article about Overview of SOA Programming Model and Runtime System for Windows HPC Server 2008 from MSDN site and I am having the following doubts.

     

    Doubt #1

    While Copying and Placing the Service DLLs, it has been mentioned in local deployment: updating service binaries will be time consuming

    What do you means by updating service binaries?

    Doubt #2

    In Hybrid deployment: Some large, not-so-frequently-updated service binaries are copied to the local nodes, while the small or more frequently updated services are copied to a file share.

    When frequently used files are shared; whether it will lead to traffic and time consuming then copied to local nodes?

    Doubt #3

    While running SOA application, The SOA client application initiates a session with the Job Scheduler.

    Whether we can run parallel task in a session or for each task a client has to initiate a session?

     

    Help me out

    Thanks

  • Hi Benita,

    To answer your questions:

    1) Q: What do you means by updating service binaries?

    A:  Service binaries = Your SOA service dll and its dependencies. They must exist on each compute node.

    Updating means: in case you change your service code,  you may want to update the dlls.

    2) Q: When frequently used files are shared; whether it will lead to traffic and time consuming then copied to local nodes?

    A: yes, if frequently used files are shared, they'll lead to traffic. recommendation: copy to local nodes.

    3) Q: Whether we can run parallel task in a session or for each task a client has to initiate a session?

    A: you cannot run parallel tasks in a session. but you can create a shared session. then use multiple tasks, each task will create a client, the client then use this shared session.
