Subject RE: Questions about Custom Application Registration and Complex Input/Output Data
Date Thu, 20 Nov 2014 15:10:53 GMT

Hi Everyone,
Since I haven't received replies in last 10 days and the open issues are for me now very blocking
I just refresh my currently still open questions trying to simplify the explanation. 
I have a local application on my machine that is invoked with a couples of argument (for example
2 strings), do it's processing and create some results (more or less complex). Is it possible
to wrap the execution of my local application with airavata in such a way that i can register
the application on my local airavata-server and subsequently create experiments using the
airavata-generated application interface?
How should the application invocation arguments be translated when I create the application
interface? How can I get as output of experiment the results of my applications? Which are
the steps that I should follow?

Thank you again and sorry for my harassment but these questions have become completely blocking
in the last days...

Hi Suresh and Raminder,
Thank you so much for all the explanations and the references,  there will be really useful!

Thanks again for your support,

Hi Alfredo,
I will answer this easier one first. 
You guessed it right, as it stands now, the token is a handle to a credential which is used
for compute resources. As for local resources, we can pretty much send something and i will
get ignored. The current token is described in a paper by Amila Jayasekara described at [1]
or [2] for a direct link.
One of the many reasons Airavata is holding up on a 1.0 release is to clear usage of the API
in a secured way. In general, we are modeling similar to how Evernote uses Thrift API [3].
We recently had a good long review in this context by experts [4], we will soon have a technical
paper describing Airavata API security and identity management and should have a implementation
soon there after. 
Thanks for your interest in Airavata,Suresh[1] -[2]

Hi Suresh and Everyone,
I have another question to add to my previous meanwhile,
what do sshTokenId and gsisshTokenId mean (into launchExperiment method)? In the samples are
hard-coded values.. are they really influent? At least using localhost as computeHost it's
unnecessary to use/generate them right?

Thanks again,

a certain language (let's assume python or C++) which takes some string as launching arguments,
(string1 string2 string3), it does some processing and creates a more or less complex "output"
during it's process. I want to generate an interface application on airavata of that application.
My questions are:

which I'm creating? it's always what happens comes with the stout of the system or there is
a specific procedure to follow into MyApp or before create the registration script?

object (not simple object such as string or int but more or less complex structures) wow can
translate that into the airavata Interface? .Is it supported? Do I need to register class/structure
on apache thrift server and use the thrift-generates interfaces directly into my application
in order to associate a possible airavata OutputDataObjectType?
