2. 13/05/2004Janusz Martyniak Imperial College London 2 What is Ganga? It’s a flexible GUI and CLI job submission system designed for Atlan and LHCb experiments It uses Python as the programming language and wxPython graphics toolkit (portable) It’s well structured so adding new code is easy which makes it possible to use in other experiments like BaBar by designing new modules.

3. 13/05/2004Janusz Martyniak Imperial College London 3 Ganga Basics Ganga supported (extendable) set of ‘batch systems’, like pbs, lsf, edg. GLOBUS and Condor support have been added Babar specific application types have been implemented to allow job submission under edg/lcg and GLOBUS

4. 13/05/2004Janusz Martyniak Imperial College London 4 AliBaBar – Job Submission for GLOBUS A command line submission system based on GLOBUS and AFS has been developed at Manchester. The user is supposed to create a standard BaBar setup on AFS and submit a job using a gsub command line tool. A job is submitted to a user specified gatekeeper

5. 13/05/2004Janusz Martyniak Imperial College London 5 GUI for AliBaBar A GUI panel has been designed to facilitate a usage of the alibabar submission tool It allows the user to specify important alibabar parameters necessary to submit a job. It adds multiple job handling using the BaBar specific metadata index which allows to submit jobs to many gatekeepers

6. 13/05/2004Janusz Martyniak Imperial College London 6 GUI for AliBaBar, contd. Jobs can be configured and saved for later submission Standard GANGA job monitoring is available stdout and stderr are saved with a job Jobs may be copied and resubmitted

8. 13/05/2004Janusz Martyniak Imperial College London 8 Current status and plans The system works and is currently being tested Available for user testing soon Future plans include creation of an ‘index editor’, which would allow job selection (at present all jobs in the index/data directory are submitted)

9. 13/05/2004Janusz Martyniak Imperial College London 9 wsGanga ? An experimental version of Ganga based on Web Services has been created It uses Globus GSI enabled SOAP implemented in Python (pyGlobus), a proxy is send from the client to the service along with a remote function call. It’s able to submit “Hello World” jobs.
