2. Outline
APIs/commands
GUI
Some Issues

3. APIs - C++ (1/4)
Development of C++ API terminated for the classes in the API spec
JobId
JobAd
Job
JobCollection
NotificationAd
UserJobs
UserCredential
Currently collaborating with Francesco G. for the DAG-related classes

4. APIs - Java (2/4) Completely rewritten
JobId
Completely rewritten using the Java ClassAd package
JobAd
Use of JNI to wrap RB/LB APIs (development still on going)
Job
JobCollection
NotificationAd
UserJobs
Use of Globus CoG package
UserCredential

5. APIs/commands (3/4) Never tested integration with RB/LB
Only unit tests could be performed
stubs for RB/LB
ClassAd C++/Java not always aligned
There are missing Java methods
Not continuously maintained
Will have to change behavior in some methods/commands due to the new architecture. Many details are still missing for the job control commands:
Job cancel
Job output retrieval
Input sandbox transfer

6. APIs/commands (4/4) Gradually including new functionalities:
MPI - done
Interactivity – done only for the command-line
Not yet clear how to manage it within the API
DAG – just started
Checkpointing – not yet started
We strongly depend on the other components
Investigating possible wrapping (SWIG) of ClassAd/JobAd for use in the command line UI

7. GUI JDL Editor Job Monitoring component
Development almost complete
Accept/produces JDL/XML job descriptions
Need to be updated with new attributes
Also thinking to a ‘DAG Editor’
Job Monitoring component
Development begun
Short term/Long term solution agreed with CESNET People
Polling
Notification (from R-GMA?)
Is a Job Submission graphical component needed?
API seems to be sufficient
Will investigate possibility to write a pure Java Network Client (incl. Security)
As an applet seems not to completely solve the security problem raised during Genius demo (proxy)

8. Some Issues JDL: Bypass (grid_console) Make [] mandatory
Make JDL case sensitive (as classad is)
Multiple line attributes (\ no more needed)
Slightly change comments formats (//, #)
Support for JDL file containing multiple job descriptions
Put OutBoundIP automatically in job requirements if staging in/out is needed (it is already the case for interactive jobs)
Put Active automatically in job requirements
Impacts from GLUE
Bypass (grid_console)
Separate component (third party)
Part of UI
