1. RDIG for ALICE today and in future
ALICE Task Force meeting, November 2008, CERN
RDIG for ALICE today and in future
Galina Shabratova
Joint Institute for Nuclear Research

2. Largest part of RDIG-Russian Data Intensive GRID –distributed Tier2 involved in to processing of ALICE activity
Today 9 RDIG sites support ALICE computing
All 9 sites are submitting ALICE jobs under WMS
5 sites installed SE::xrootd, an additional site has to install SE::xrootd till the end of November 2008
1050 kSi2k and 210 TB are pledged for ALICE.
There are 203 TB have been already installed at SEs::xrootd at 4 sites.

8. Analysis activity
Today members of Russian institutes & JINR are participating in the analysis of ALICE as simulated as test beam data: at CAF as members of PWG2 and PWG4, in the processing of batch analysis
In these days there is under installation a PROOF facility at JINR for all ALICE teams in Russia and JINR. As a first step this is one 8 cores machine.

9. What services are planning ?
Installation and test of CREAM-CE at one RDIG site as a first step – RRC-KI. After the analysis of experience and operation of this site under CREAM-CE will be done decision about migration of other sites: how and what sites will be next.
From the beginning of next year will start installation of pure xrootd at the base of new(not installed yet) disk resources. Today there is started the pure xrootd installation at new RDIG site –MEPhI ( ~7TB).

10. What about future resources?
It has been announced requirements of ALICE CB to future RDIG resources in accordance M&O to the RDIG management to yy.
These requirements are now under investigation of RDIG management.

11. Request to ALICE computer management
Together with WLCG to agree the accounting procedure for DISK resources will used under pure xrootd as the official contribution to ALICE GRID.
