Re: [geclipse-dev] Transferring local input files during job submission

Hi Mariusz

Some questions pop up for me. (see also your mail to Ariel/the list
before).

How is this working? You mentioned in the mail before, the following 
> So, as I understand input files workflow is:
> local machine -> CE -> WN
Here my question is: Do you not need a WMS? How does the Grid find out, which 
CE to use? 

So I see the process a little bit more complex: 

1. User defines the JSDL on his local machine
2. User submits the JSDL
2.a JSDL is transferred to MWS
2.b WMS selects a computing element (CE) to execute the job

3. The CE uploads the file 

4. The CE start the execution. 

5. CE notifies the WMS/L&B about the completion of the job. 

6. local machine can get the results from the WMS/L&B system


So still my question is: When is the file uploaded to the CE?? We still 
have the WMS in between the local computer and the CE. 


> This uploading will be part of job submission: if user cancel uploading, 
> whole job will be treated as not submitted.

And perhaps we have to clear WHO is doing what!!
Is it the WMS and CE which takes care on the upload?? 
Or is it the "Submission job" in g-Eclipse which is a set of subtasks? 
(JSDL transform, CE determination, File upload, Job submission)? 

Cheers
