Hi Mariusz
Some questions pop up for me. (see also your mail to Ariel/the list
before).
Maybe I will try to clarify a bit.
How is this working? You mentioned in the mail before, the following
So, as I understand input files workflow is:
local machine -> CE -> WN
In fact it is:
local machine -> WMS -> 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
JDL, not JSDL
2.a JSDL is transferred to MWS
yes, in 3 steps:
1. Job is registered
2. files are transfered to WMS input sandbox
3. job is started
Local machine can be now switched off, as it does not partiicpate in the
later processes.
2.b WMS selects a computing element (CE) to execute the job
3. The CE uploads the file
yes, but CE transfer files from WMS sandbox and not from submitting
machine
4. The CE start the execution.
5. CE notifies the WMS/L&B about the completion of the job.
yes, and outputsandbox files are transferred to WMS
6. local machine can get the results from the WMS/L&B system
I hope now it solves all doubts.
