**Slow due to lack of manpower and commitment to a common plan**
- Participate in the inclusion of CMS luminosity and Data Quality information into the data discovery and bookkeeping systems to facilitate data analysis.
**In Progress**
- Milestones: DBS met the goals set forth for both the challenges and global run activities
- Risks:
- Frontier continues to require investments of effort to function in the CMS context, CMS is pushing for an increased long term FNAL commitment for support, and the distributed calibration system creeps farther toward online
- The progress toward information consolidation in the data management system is proceeding slowly

## Project Activity: Distributed Computing Tools

- 1.	Prepare ProdAgent for use in CSA07 (September and October 2007)
- a.	Demonstrate management of 2500 job slots
**Met for CSA07.     Tier-0 job slot management and basic functionality achieved**

## Project Activity: Distributed Computing Tools

- Key Milestones -
- The successful demonstration of basic Tier-0 functionality in CSA07 was a key milestone
- It also became a driving force for refined development
- The upcoming major milestone is the delivery of a fully functional Tier-0 needed for data taking
- Risks
- Addition of two former Nova developers has been a big help
- Production tool program continues to be subject to risks associated with the loss of key individuals
- The International CMS decision to adopt a common infrastructure for simulation, data reprocessing, and data simulation was technically the correct one
- Though certainly and increase in scope

## Project Activity: Contribution to CMS CPT

- Contribution to CMS CPT was not so much of a tactical plan but a list of people engaged from CD in management activities of the international experiment
-  **People expected to be involved when the plan was written in June 2007**
- Patricia McBride will serve as deputy CMS Computing Coordinator
- Elizabeth Sexton-Kennedy will serve as Level 2 manager for the CMS Software Framework
- Ian Fisk will serve as CMS Integration Coordinator
- Daniel Elvira will serve as Level 2 manager for the CMS Simulation Project
- Don Petravick will serve as the CMS Network Liaison
- Matt Crawford will  continue to serve in Network optimization
- Yulia Yarba and Sunanda Bannerjee will participate in the simulation development
**Changes in 2008**
- Dave Evans took on the responsibility of Level 2 Manager for Data and Workflow Management
- Daniel Elvira stepped down as Level 2 for CMS Simulation
- Don Petravick became otherwise engaged in Washington, DC

## Project Activity: Grid Services and Interfaces

- 1.	Participate in solving scaling issues and debugging problems with grid interfaces to storage and processing at the Tier-1 and Tier-2 computing systems for US-CMS
- a.	CMS dedicated scale testing in September and October (CSA07)
**Successful demonstration of OSG services during CSA07 and in pre-challenge**
- b.	Dedicated computing drills of specific scenarios planned for February and March of 2008
**Dedicated computing drills are now called CCRC and are February and May**
**February tests of Storage interfaces were successful **
- 2.	Participate in the OSG Integration Project to ensure interoperability of the OSG with the EGEE services for CMS and functionality of CMS specific services on the underlying OSG infrastructure
- a.	On-going program of work
**This requires vigilance as new SRM implementations are deployed and in the coming year as both OSG and EGEE deploy new CE technology.**
**Nevertheless the current level of interoperability is a remarkable success **
**CMS production and analysis tools submit to both grids.   It is somewhat disappointing that OSG sites appear to the EGEE resource broker but EGEE sites are not easily used by direct submission, but this may be made moot by the addition of pilot job implementations.**

## Project Activity: Grid Services and Interfaces

- 3. Ensure all CMS grid services are properly accounted and auditable to meet the security requirements of the Tier-1 and Tier-2 sites
- a.	Complete deployment of Gratia
**Gratia Available on all US-CMS Tier-1 and Tier-2 sites**
**Accounting data reports are useful and become more comprehensive **
- b.	Evaluate auditing procedures for processing and storage interfaces to sites
**This is lacking for storage elements.   Becoming critical as users begin to utilize storage**
- c.	Complete the deployment and distribution of gl-exec
**gl-exec is in production at FNAL and in deployment at Tier-2 sites**
- 4.	Complete deployment of OSG SAM tests to ensure all sites function and availability can be tracked
- a.	Track and solve problems identified by the CMS specific SAM tests
**This is currently in the final staged of deployment and commissioning**
**It is later than expected **
- Complete glide-in development, testing, and commissioning
- Roll out of glide-in WMS into operations
**Currently in production use for organized processing at FNAL**
**In evaluation for analysis processing both for US and International CMS**
**Speed of EGEE Computing Elements seen as an issue**

## Project Activity: Grid Services and Interfaces

- Deploy OSG 0.8 and OSG 1.0 to US-CMS Computing Facilities at a time-frame appropriate for CMS.
**Rollout of OSG 0.8 is complete.  Largely uneventful**
- Transition Mona Lisa development work to maintenance and operations
**Under discussion**
**Complicated by the perceived dependence for networking**
- Interface CMS monitoring and dashboard information to US equivalents in OSG and US CMS Tier-1 facility as needed for operations and debugging.
**This is an area we have lacked sufficient manpower to do.   Day to day issues have consumed available effort to improve long term more stable operations**
- Participate in CMS operational security activities interfacing to the Tier-1 facility and OSG security.
**Continuing **

## Project Activity: Grid Services and Interfaces

- Key Milestones:
- Availability of automatic accounting information from T1 and T2 sites to WLCG was a key milestone
- Completed.    Need also to complete the availability monitoring, which has been elevated in importance recently
- CMS is interested in seeing the Glide-in WMS work moved into production and exposed to data ops and users
- Coming this spring
- Risks
- The effort available to Grid Services has improved with the filling of the grid operations and grid debugger position
- The need for routine operations can put stress on the ability to perform forward thinking development and integration

## Project Activity: Project Management

- 1.	Maintain an up-to-date project WBS for the US-CMS Software and Computing Project
- a.	Participate in the change control process
**Change control process is well defined and exercised at the appropriate levels**
**WBS is being simplified.    Alignment with other research program planning and tracking tools**
**Currently limited by the bandwidth of individuals**
- Report progress to lab management through regular Project Management Group (PMG) meetings
**Meet through the Technical Advisory Board (TAB)**
**PMG meetings are being restarted after a long hiatus **
- 3.	Participate in the semi-annual funding agency reviews
**The US-CMS Software and Computing Project has a major review once a year and a mini funding agency review roughly six months later**
**Last review was February**
- Complete the yearly Statements of Work (SOWs) with the universities supported by the software and computing project
**This generally takes us longer than it should.   All are completed, but the goal for the next round is to finish them more promptly**
- 5.	Complete project status quarterly reports
- Ensure each level 2 project reports progress, status, and schedule issues
**Status reports are written quarterly for all level 2 subprojects**
- Participate in the re-design of the CMS project web pages
- _[www.uscms.org](http://www.uscms.org/)_
**Still in progress, but new structure is in place**

## Project Activity: Project Management

- Milestones:
- Major obligations of Project Management are met
- SOWs
- Reviews
- Reports
- Risks

- 2.	Provide dedicated physics support for LPC residents in using CMS analysis code and infrastructure.
- a.	Hire a physics support specialist for the LPC
**Budget has been identified to support 2-3 people in physics support**
**Looking at more creative ways to find people in the absence of personal requisitions **
- Continue the engagement of CD supported personnel in US-CMS LPC physics work and international CMS physics groups.
**A number of local LPC users are actively engaged in CMS physics groups**
- Provide tutorials and documentation for users as needed (roughly quarterly during the final year of preparations).
- Software and analysis tutorials have been offered in FY08
**Milestones: LPC continues to grow in numbers of people and level of activity **
**LPC members are leaders in physics analysis preparation activities and some commissioning activities **
**Risks: LPC had reasonably ambitious plans for hiring physics support personnel, most of which have been hampered by hiring problems at FNAL**
**As the activities grow the load on the existing people will grow**

## Project Activity: Software Development and Support

- 1.	Release of CMSSW_1_7_0 (Production release expected Oct. 12).
- a.	Includes backward incompatible geometry changes.
- b.	Intended for HLT Commission exercises

- b.	This implies that future 2 series releases will be required to be backward compatible with 2_0_0.
**Production available this week**
- 4.	Start of running early summer 2008.
- a.	This will be a period of rapid releases as problems are encountered reconstructing real data.
**Start of running now estimated at the end of summer with single beam studies expected during the summer**
**The release of CMSSW_2_0_0 was a major milestone.    The delay of the software roughly corresponds with other detector and accelerator delays**
**The upcoming release of CMSSW_2_1_0 will be carefully watched**
**The version expected to be used for simulation of the detector conditions during the summer and the beginning of data taking**
**Reasonable pressure to enforce backward compatibility in data formats**
**Software development continues to be sensitive to losing effort from individual developers**

## Tactical Plan Issues and Risks

- The most significant risk to the CMS program of 7 tactical plans for development and integration is the inability to get the effort we need and have resources for
- We are significantly down from the plans in terms of integrated effort.   Only a few goals are completely missed, but many are shifted by several months.   Chance of further slip is high
- Furlough and mandatory vacation makes the situation worse
- Unclear impact of the RIF.
- We have been asked by the research program to identify money that will not be spent in FY08.
- Globally CMS has many needs

## Tactical Plan Status Summary

- Application Services
- CMS is making good progress on the Dataset Bookkeeping system
- Heavily used for discovery and data operations
- Work needed for luminosity and conditions
- Data will come in about 3-4 months and there is work left for describing real data
- Frontier is functioning well, but as the complexity of the data increases we find work is needed.
- Expectations of long term operations we cannot deliver
- Distributed Computing Tools
- ProdAgent infrastructure has been a big success and the common components will serve us well in the long term
- The increase for the Tier-0 workflow tools is a lot of work and is a high priority as data is arriving
- Grid Services and Interfaces
- A number of sometimes loosely connected projects
- Accounting work has been a big success
- Integration and debugging puts US-CMS in an excellent position for the beginning of the experiment
- We expect good things of the WMS project

## Tactical Plan Status Summary

- Project Management
- We are generally meeting our obligations, which continue to grow
- Need to make progress on simplifying the WBS and spreading the load
- Contributions to Offline and Computing
- FNAL is well represented in the CMS Offline and Computing Management structure
- LPC Desktop and Physics Support
- We’re able to make the LPC an attractive place to work from the technical standpoint
- Good computing and physical infrastructure
- Need to enable the physics support

## Tactical Plan Status Summary

- Software and Support
- Big demands on the software developers from CMS on the framework and the software in the last months of preparation
- We are typically shifted from our schedule at the beginning of the fiscal year by ~2 months
- So is the accelerator
- Good progress toward preparation, though a busy 3 months ahead.

## Software and Computing Achievements 

- Software Progress
- CMSSW 2_0_0 is in pre-release and a production release is expected early this spring
- This is the 3rd major CMSSW release since October
- Significant improvements in the Higher Level Trigger data format and the memory use of the application
- US-CMS is making significant contributions to the software integration and optimization effort
- CMSSW 2 has successfully demonstrated the ability to synchronously read from two files
- This allows the experiment to efficiently write raw and reconstructed data in independent files
- This was a critical component for the start of the Spring and Summer challenge exercises
- CMSSW 2_1_x is the release CMS expects to use at the start of CMS

## Software and Computing Achievements 

- Workflow Progress
- All organized processing in CMS is based on the Prod_Agent framework
- strong contribution to architecture and development from the US.
- Around 80% of the processing resources in the experiment are controlled by processes submitted by Prod_Agent
- CSA07 workflows for central processing were controlled by Prod_Agent
- deficiencies were found during the
-       challenge and a more functionally
-       complete Tier-0 expected in the
-       Spring
- Components are used in the CMS
-        global runs to test under more
-        realistic data taking conditions

## Starting in the late fall the WLCG (EGEE and OSG), the Tier-1 and Tier-2 sites, and the LHC experiments began the migration from the Storage Resource Manager (SRM) version 1 to version 2.
This involved development effort on services and mass storage implementations from CERN, FNAL, LBL, and DESY
Coordinated service upgrades from the sites and the experiments
The change of SRM protocol is the most significant migration in the grid interface to storage since the WLCG adopted SRM from simple GridFTP more than 4 years ago

## CSA07 Commissioning

- In terms of data stored at Tier-1 center mass storage and number of re-reconstruction and data skimming passes completed, CSA07 is comparable to the data that had been expected in the 2007 engineering run
- More than 1PB of data was written to tape at FNAL
- 3 reprocessing passes were completed with various calibration scenarios
- Roughly 50 physics defined skims were applied to the reconstructed data
- Hundreds of thousands of skimming workflows to create the samples
- CSA07 exposed a number of areas where additional development was needed
- Workflow and application problems were uncovered
- Data format size and memory footprint issues were identified

## Commissioning Data Operations

- In 2007 CMS developed a data operations model with two equal teams one at CERN and one at FNAL
- Take advantage of the time offset to cover more of the day during business hours
- Maintain close connections with the developers in Europe and the US
- CSA07 was an opportunity to exercise the model
- The two teams began during the challenge to function as a unit
- One coordinator at CERN and the other at FNAL
- Daily handoff meetings between the operations team members
- Shared workflows and shared utilization of CERN and Tier-1 centers
- Since the completion of CSA07 data operations teams continue to function efficiently
