Subject RE: Experiment launched never ends

Hi Shameera,
thanks for your reply!
So you are saying that the only way to obtain an output with a significan value is to provide
to a certain input the <outputname>=Outputvalue ?
There is no way to associate the output values to possibles result obtained in my application

Let me know if I have understood wrongly....

This afternoon I'm going to try again the creation and launch of simple experiments to check
if still persist the issue of not conclusion of my experiments.

Thank you again!

Hi Alfredo, 
Airavata output handlers in GFac read output against it's output name, otherwise there is
no way to map correct output values with correct names. That is why you get the output when
you provide <outputname>=StringToBeEchoed. Echo application is an ideal case but in
general we may have more than one output in that case we need a way to map correct outputs.

If experiment stays in the executing state and won't go to complete/failure state, if there
any issue in output mapping then that is a bug and we need to fix this. Please create a JIRA
for it. Meanwhile I will try to reproduce it and fix. 
Application with no output is bit odd to me. I am not quite sure whether we are handling such
a situation in airavata. may be someone else in the list can answer to this.  

Thanks, Shameera.

Hi Everyone,
I'm really sorry to bother you again, I'm testing a couple of customized (simple) application
- Echo Application (following the provided sample, 1 input and 1 output)
- LS application (customized app using the ls command, 1 input and 1 output)
When i try to create and launch experiments with those application (I'm not using xbaya anymore,
I'm working directly with the code). When I check the status of the experiment I have only
experiment in "EXECUTING" state that never ends. Is it normal? What are the condition to "COMPLETE"
the experiment?

Furthermore, printing the output value of experiments I have the following situation:
- Launching echo experiment I have no output value empty if the input value is a general string.
Only if I assign a string with this syntax <OutputName>=StringToBeEchoed as input value
I have the output with that value. 
- With the LS application I have no output value in any case.

This "strange" behaviour is due to the fact that the experiments stay in EXECUTING state and
never complete?

Thank you again,
