Subject Re: Airavata Workflow Interpreter Emulation Framework
Date Mon, 25 Mar 2013 18:10:50 GMT
Hi Suresh/Saminda,

After reading the paper, i have come up with this,

1. we need a configurable interface to customize the data required to start
emulator.
2. Application emulation -  Dummy applications(proxy services) can register
via Xbaya, once the dummy application receives the input message, it
invokes the task state simulation chain and returns the output to the
workflow.
3. Application availability and Failure model - to provide a better real
world scenario, user can config the failure rate of each task state as
user's requirement.
 4. Pluggable interface to grid emulators and cloud emulators.

We need to find/develop a good Failure level management algorithm to
provide better real world simulation interface, and
 scalable to handle large number of workflows.

However, may be, implementing all above mentioned features will not be the
best fit with scope of GSoC.

This is just my initial idea after reading the paper. I would like to know
all of your ideas in improving this further. WDYT?

Thanks,
Shameera
