* JIM migration from sam v5 to sam v7
Gabriele Garzoglio
Dec 02, 2005

The following is the WBS of the project and a time estimate for its completion.

Using the PERT Multi-point estimate rule, the total estimated FTE days for the project is (43 +- 3). 

2 FTE can work in parallel during the development phase.
Essentially no parallelization is achievable during the integration phase.

Considering the 15-15 rule for working efficiency and week ends (holidays are not considered), the total estimated calendar days to complete the project is (60 +- 4). This estimate can extend to (72 +- 5) days if the porting of jim to python 2.4 fails and the contingency plan is enacted (see "contingency" section in the "Integrate system" item of the WBS).

NOTES:
Assumptions are noted next to the relevant activity in the WBS.
All time estimates are expressed in FTE days and are rolled up using the PERT Multi-point estimate rule.


- Port jim software suite to python 2.4.
-- Perform show-stoppers tests (critical porting). 
   Time: (3.0 +- 0.7) (min 1, max 5, most-likely 3)
--- xmldb_client (uses XML RCP libraries)
--- xml_meta_configurator (uses pyxml intesively)
-- Perform tests of the complete suite.
   Time: (3.2 +- 0.5) (min 2, max 5, most-likely 3)

- Implement required commands to sam v7
-- Port "sam get dataset" command from sam v5.
   Time: (2.0 +- 0.3) (min 1, max 3, most-likely 2)
--- Lightweight consumer in poll mode
--- Lightweight consumer in call-back mode (IS THIS NEEDED?)
-- Add "poll"-mode to the station v6 routing interface (for LCG).
   Time: (4.8 +- 0.8) (min 2, max 7, most-likely 5)

- Port execution site software suite to sam v7.
-- run_grid_job.py and plug in (jim_job_managers).
   Time: (2.0 +- 0.3) (min 1, max 3, most-likely 2)
-- wrappers (jim_job_managers): check the use of the sam command line commands.
   Time: (1.2 +- 0.2) (min 1, max 2, most-likely 1)

- Port cliet site software suite to sam v7.
  Time: (3.0 +- 0.3) (min 2, max 4, most-likely 3)
-- Port "check job consistency" modules (interaction with db server)

-Integrate system
-- Integrate JIM (new sam_client software distribution).
   Time: (1.2 +- 0.2) (min 1, max 2, most-likely 1)
-- [ Contingency:  What if we cannot port JIM to python v2.4?
     Distribute different python versions for JIM and Runjob to the worker node.
     Time: (min 4, max 10, most-likely 6)
   ]
-- Integrate Runjob.
   Time: (14.5 +- 2.2) (min 7, max 20, most-likely 15)
   (ASSUMES:
       o Runjob integrated with SAM for data storing and MC request system
       o Runjob developers presence
   )
-- Integration tests.
   Time: (8.5 +- 0.8) (min 5, max 10, most-likely 9)
