[kepler-users] [kepler-dev] How to add slaves in a remote workflow in Java(in Eclipse)

[Neha Sharma]

Hi Jianwu,

Let me first Thank you for the information on the master slave module. The reason why we are trying to simulate the workflow in eclipse is that we are trying to evaluate workflow engine for one of our project. Kepler is built on Ptolemy, but Kepler includes lots of other features including Distributed Composite Actor(I guess). We want to use this with our project, and that is why we are exploring this.

Regards,

Neha Sharma

Hi Neha,

    First of all, I haven't seen anyone working on workflow simulation in Eclipse before. Your work is very interesting. May I know why you want to do it? I guess you are not just replacing Kepler GUI with another GUI, right?

    The code of master-slave module is done long time ago. So my information on the interfaces below is just my best guess. You have to verify its correctness.

    1) How do I add slaves? At the construction function of org.kepler.distributed.MasterController class, it tries to read available slaves.

    2) How do I allow/deny Access? The function processUserInACL() in org.kepler.distributed.SlaveController class will check whether the user is allowed or denied.




Best wishes



Sincerely yours

Hi,

I have successfully implemented the remote workflow using Kepler's GUI. I am now trying to implement the remote workflow by writing a simple Java code in Eclipse.
The reason of doing so is that I want to create a new User Interface and not use the existing swing UI. When writing the code to create the remote workflow I face the following problems:


1.       How do I add slaves? (In Kepler I could do this by clicking Tools->Distributed Computing Options)

2.        How do I allow/deny Access? (Clicking Tools->Distributed User Access Configuration helped me with the access configurations in Kepler.)

Which API’s should I use to add slaves and configure their access? I intend to simulate the entire workflow in Eclipse. Please help.

Regards,

Neha Sharma
