Hi Shameera,

Thank you for taking time to digest the paper and come up with these excellent points. Can
you please add these to JIRA so we don't loose them. I would agree with you these may not
be well scoped for a GSoC project. Please stand by a day or two, we will try to recast all
GSoC projects.

Cheers,
Suresh

at the code recently as well.

we offered as GSoC projects last year and we are resurrecting it now. I will advice the students
to shamelessly steal ideas from your paper.

paper [1] saved me some time. Why don't you read through the paper and propose back concrete
GSoC tasks you see as applicable to current Airavata Workflow Interpreter. Do not worry to
take the approaches literally and be liberal in your thinking and implementation. But the
paper should give you a good head start. As you explore Airavata, just throw some ideas and
we will help you refine them.

Saminda/Suresh/devs can you provide me more details or shall we discuss in improving this

Effectively it will be behaving exactly as a GFac server/message box/registry etc but with
hard wired data. As an example ideally it would be like the Azure simulator I guess.
