Purpose
This page gathers information which is used to show where data from the ATLAS Full Dress Rehearsal will be placed within Tier-2 sites in the UK.
DPDs
Personally produced DPDs should be registered at AtlasFdr1Dpd
FDR-1 placement at Tier-2s
Decision has been made 13/2/08 based on information received in time
- Placement is based on a combination of the physics requests made by the groups by 13/2/08 (in the table at the bottom of the page) and the readiness state of the sites as determined by ATLAS UK computing. Please see notes below for more information.
- This is for FDR-1 only. We will do a further iteration for FDR-2.

Trigger to Stream matching for Full Dress Rehearsal-I
For information on the streams see: http://tbold.web.cern.ch/tbold/view_menu.php?name=lumi1E31_13.0.40

Information Gathering from Sites for FDR-I:
FROZEN 13/2/2008 - AJB
The streams are: EGamma, JetTauEtmiss, Muons, MinBias (+ not for physics: Calibration, Express)
The notes for the sites were as follows
- This placement is for FDR-I only, and will change for FDR-II
- The purpose is to do as complete a test as possible of the distributed computing model, so your data of interest may not be (indeed is likely not to be) at your home site. This is deliberate! All the data would fit easily at every site, but if we put it there we do not test the tools we will need for larger data-sets.
- Each Tier-2 cloud will hold a complete set of AOD, but, in order to test the distributed computing model, not all sites will do so.
- To reduce traffic, we will try to make some mapping between physics interets and data placement
- List your site's physics interests in some sort of order of priority, depending on likely maximal usage from people at your site.
- The initial list is based on sketchy partial initial information. If it is wrong, please dont complain, but fix the table for your institute and send me a message to say what you have done.
- Please include between one and three streams. The actual number of streams placed will depend on the relative data volumes and other factors.
- If possible, include approximate number of people analysing the data (of this FDR) in brackets after stream name.
- FTE is the number of people at your site who will be actively involved in analysing the data for this FDR on that' stream. If people are working on more than one stream, divide their FTE across streams.
- SRM2.2 is the Storage Resource Manager version required for participation in the FDR. Your site needs to have this installed.
Sites were requested to list their preference for which streams to host in order follows.
Tier-2 | Site | SRM2.2? | Stream1 | FTE | Stream2 | FTE | (Stream3) | FTE |

Is your site in a suitable state to receive data?
Placement of data will be prioritised at sites which are functional. To check your site see:
