## CDFII Computing group changes

- S. Belforte keeps for the moment 20% (1 day/week) on CDF: necessary to guarantee the transition
-     toward a new “responsabile nazionale”
- The CDF-Italia projects for software and data handling  are mature and well under control :
-  transition from “our machines at FNAL” to “our farm at CNAF” completed with success
-  our CNAF farm merging into the Tier1 common
-     pool almost completed
-  new software infrastructure for CAF re-written
-     by Igor Sfiligoi co-head “Computing and Grid”  for
-     CDF at FNAL

- Presented by Stefano Belforte @CN1 for CMS

## CDFII Computing group changes

-  Transition toward  GRID started and very promising
-  Our budget  ~0 Euro since two years
- New people arrived in the latest 12 months and new very important role of Igor Sfiligoi:
- Donatella Lucchesi (art. 23 – Padova)
- Francesco Delli Paoli (borsa tecn. INFN – Padova)
- Armando Fella (borsa tecn. INFN – Pisa)
- Subir Sarkar (A.R. tecn. Tier1 – CNAF)
- Daniel Jeans (A.R. tecn. INFNGRID – Roma)
-  New group organization

- Porting of CAF to LCG

- CAF and GRID for CDF

- Presented by Stefano Belforte @CN1

## CAF status at Fnal (latest 6 months)

- Italian Users on CondorCaf

- All slots used, relative
- high demand before
- analysis approvals for
- conferences

- CAF reserved queue ~300 GHz

## CDF al CNAF 2004:

**CDF al CNAF 2004:**

- From 8 to 80 boxes.    From FBSNG to Condor

- December: + 22TB disk
- data import ~200Mb/s

- Fair share: 800 users, 54 active last month

-  NFS stinks, GPFS ok
-  RFIO ok
-  Condor great
-  Glide-In in progress

## Towards GRID: Glide-in

- Just a small change over the production Condor based CAF
- Use glide-ins to extend the Condor pool
- A dedicated head node must be installed and maintained near the Computing Element
- CDF user policy in our hands
- Use dedicated storage
- In beta testing stage now at CNAF
- Test users have access to 500KSI2K of CPU

- Work done by Subir Sarkar and Igor Sfiligoi

- Presented by Igor Sfiligoi @IFC, April 15

## Towards GRID: Glide-in

-  CDF users are submitting jobs via GlideCaf to
-    common resource @CNAF (farm LSF)
-  We have access to 1.1 THz in principle
-  Need to define CDF dedicated resources when LHC
-    Data Challenge
-    will be in

- Donatella Lucchesi

- 22/04/2005

## Bottom Lines 

-  Everything works:
-  CAF @ FNAL and  CAF @ CNAF **OK**
-  Resources @ CNAF **OK**, usage ~80%
-  CAF extension @ CNAF to  “pool comune LSF” **OK**
-  LCG portal  **OK**
-  Users happy, analysis not limited by resources
-  Impossible to define now if and when we will have  crisis
-  Compare CDF 2008/9 with “Tier1”=resources pledged to
-     INFN for LCG @CNAF as RRB of  LCG of April
**http://lcg.web.cern.ch/LCG/C-RRB/2005-04/RRB7_Report050405.pdf**
-  CDF cost is  low
-  2005/2006 covered by what already approved
-  future   next slides

## Disk Space

-  CDF produces ~100 TB of data per year
-  ~20% comes to CNAF  20TB per year
-  Same amount of disk space considered for Monte Carlo
-     Ntuples and reduced  datasets homemade
-   End of 2005 CDF has 90TB
-     (80 from CNAF)
-   Small expansion:
-      +40TB/year
-   CDF is a small fraction of
-      CNAF/Tier1 program
-  Years of reference: 2008/9
-     CDF = 4~5% of Tier1

| Year | TB CDF | TB T1 | %CDF |
| --- | --- | --- | --- |
| 2004 | 10 |  |  |
| 2005 | 32 | 200 | 16% |
| 2006 | 90 | 850 | 11% |
| 2007 | 130 | 1500 | 9% |
| 2008 | 170 | 3500 | 5% |
| 2009 | 210 | 5600 | 4% |
| 2010 | 250 | 9000 | 3% |

## CPU: “Assisi” CDF requests

-  Scenario presented in 2004 (3 times) based on
-     CDF official expectations presented by Rick Snider
-     and not changed as today
-  CPU for CDF-Italy users:
-     linear increase as  20042005
-  CPU for  CDF: 15% of total needs as presented
-  In the reference year 2008/9 CDF ask for CPU as
-    Atlas or CMS
-  Not crazy, but difficult to make now the case
-  Today proposal: we will ask so much when and if  we
-     need

## CPU: “Assisi” CDF requests

| Year | CDF
(KSI2K) | T1 
(kSI2K)  | %CDF |
| --- | --- | --- | --- |
| 2004 | 86 | - |  - |
| 2005 | 495 | 1300 | 38% |
| 2006 | 903 | 1800 | 50% |
| 2007 | 1505 | 2400 | 63% |
| 2008 | 2107 | 6300 | 33% |
| 2009 | 2709 | 10500 | 26% |
| 2010 | 3311 | 18000 | 18% |

## CPU: exercise “crescita zero”

-  Assuming, as exercise, that starting from  2006
-    CDF does not buy any CPU we have 900 KSI2K
-  In the reference year 2008/9 CDF is 12% of Tier 1
-     a bit less of ~1/3 of Atlas o CMS
-  Not surprising, CDF will have ~10PB of data
-  CDF will not be  “insignificant” in any case

## CPU: exercise “crescita zero”

| Year | CDF
(KSI2K)  | T1 (kSI2K) | %CDF |
| --- | --- | --- | --- |
| 2004 | 86 |  |   |
| 2005 | 494.5 | 1300 | 38% |
| 2006 | 903 | 1800 | 50% |
| 2007 | 903 | 2400 | 38% |
| 2008 | 903 | 6300 | 14% |
| 2009 | 903 | 10500 | 9% |
| 2010 | 903 | 18000 | 5% |

## CPU: “in medio stat virtus”

-  But, CDF does not disappear
-  A small increase per year is needed:
-   luminosity will increase and data as well
-   to have something to count on  in case GRID or
-     FNAL are  too loaded
-  give the possibility to redefine each year
-   the increase (positive or negative)
-  Assumption:  increase of 300 KSI2K/year after 2006
-  In the reference year 2008/9 CDF is 15% of Tier 1
-    to be compared with 12% if  “a crescita zero”

## Summary

-  CDF-Italia has a group of people working on Computing
-     and Data Handling which has been reorganized to cope
-     with Stefano leave
-  CAF@CNAF is highly used
-  Several datasets stored @CNAF and used for analysis
-  Big improvements towards GRID:
-  GlideCaf used to produce Monte Carlo
-  working hard to have LCG based CAF
-  Requests made in Assisi still valid for disks and CPU
-  Different scenario also presented to have possibility
-     to discuss each year our needs based our and LCH usage
