## Budget Planning in Computing Division

- Driven by a number of “Needs”, some (*) with associated planning processes and documents
- *Experiment Computing Needs
- *Data storage Needs
- *Operations Manpower Needs
- Need to continue to evolve computing and software
- Need to align Run II computing to  Global Grid Computing
- Need to reduce staff while assuring Run II given high priority and adequate resources
- Need to provide core services and common computing fabric that D0 (and many others) rely on
- Need for reasonable equity between CDF and D0
- Need for balance across Fermilab scientific program
- Need to help Beams division

## Budget Planning in Computing Division

- *Experiment Computing Needs
- Early planning with docs and many external reviews (Von Ruden)
- Initial computing and analysis systems planned in 1997 are in place (total of $18M of equipment for Run II expts)
- Must augment systems to cope with data and replacements (disk + CPU replacement rate: 20-25%/year)
- Needs for 2002-2005 were assessed by the Run II computing review in June 2002 (Bird)
- Both experiments assessed needs and requests of $2M/year
- Substantial additional resources needed at remote centers (more so for D0)
- *Data storage Needs
- Addressed by above planning
- Subject to refinement based on data formats, streaming and real-world experience + MC data needs
- Amount of storage for given budget subject to evolution of technology

## Budget Planning in Computing Division

- *Operations Manpower Needs
- An MOU was developed in early 2001 to identify effort required to “operate” D0 computing:
- Approx 33 FTE identified in a long list of categories.
- Used as a start to identify candidate FTE for operations.
- The MOU needs to be updated
- Need to continue to evolve computing and software
- Need to align Run II computing to  Global Grid Computing
- Different to detector that repair & provide consumables for  (until decide to do major upgrade project)
- Very important that Computing Fabrics, services, security models etc. evolve towards a common “Grid” way of working
- Many centers and institutions participating in providing computing for CDF, D0, LHC experiments, BaBar

## What Computing Div. provides for D0

- Considered in Common Fund

- Services (Networks, Helpdesk, Scientific Software, ....)
- Computing for reconstruction and basic analysis
- Database machines and services
- Robotic Storage and services
- Tapes
- Hardware and Software maintenance
- People to operate and support
- Computers and Farms
- Code releases
- Data handling and Storage systems
- Databases
- People to continue to evolve systems to
- Meet needs
- Support new technologies    - eg. 9940B tapes drives
- Align with Grid world
- Evolve hardware and software infrastructure
- Guest Scientist support
- Postdocs and Scientists who help with Computing issues
- WAN planning and evolution

**Operating**
- FY2003 Base Budget
- Components:
-  SWF (Salaries + Fringe)
-  Maintenance and recurring cost - includes annual software license fees
- Consultants
- Run 2 Tapes
- Building maintenance, ES&H, Travel, Education, Conferences, Hiring fees, desktop computing, miscellaneous software
- Projects:
-   Direct support for experiments/programs
-   Major identifiable projects, computing infrastructure

## Equipment
 Original FY2003 Base Budget Guidance

Run 2 Computing	    $3.0 M (sum of requests $4.0M)
All Other		    $2.0 M (sum of requests $2.7M)
Total		    $5.0 M

- Run 2 Computing	    $3.0 M (sum of requests $4.0M)
- All Other		    $2.0 M (sum of requests $2.7M)
- Total		    $5.0 M

## Base Budget Allocation by FY

***Incl. carry-over***

- Note – overheads not included
- Increasing non-base budget for
- Specific earmarked projects e.g.
- Grid projects, Lattice QCD,
- CMS Software and Computing

## FY03 Budget 

- After adjusting Base budget to reduce equipment by $800K
- After reducing D0 (and CD) Equipment from $2M to $1.5M
- After considering non-Base “earmarked” funding for special projects (Grid Projects, Lattice QCD, CMS Software and Computing, NVO, etc.)
- After lab had a voluntary retirement (3 people in CD total) and 2 others left and salary costs were cut by reducing vacation accrual
- Budget still didn’t balance by $900K

## Measures to balance FY03 budget 

- Aggressively pursue Linux-based analysis
- Reduce maintenance costs by removing processors from D0mino
- Reduce consultant costs
- “Tax” all equipment expenditures for needed Computer Center infrastructure/studies
- Move more staff to work on non-base-funded projects
- Reduce staff
- Reduce division and departmental infrastructure costs

- Vicky White - D0 International Finance Committee

- April 3, 2003

## Outlook for FY04

- Don’t expect to make the full $2M of equipment
- Keep people resources as far as possible
- Eliminate d0mino – replace by Linux Analysis facility
- Consolidate more services and support with CDF and other experiments
- Reduce dedicated staff for D0 (easier if good alignment between all expts on Grid Computing)
- Necessary to have a strong base of support at Fermilab to make Global Grid Computing model work
- Find further maintenance savings – Oracle? Sun?
