13. Grid middleware evaluations The goal of the evaluations is to get a better understanding of the functionality, performance, solidity, interoperability, deployability, management and usability of components in different grid MW distributions Aid decision about possible usage of components for the EGEE MW and about provision of interoperability between these distributions and the EGEE MW Evaluation of OMII distribution by JINR and KIAM in February - April 2005 Evaluation of Globus Toolkit 4 by JINR, KIAM and SINP MSU in May - October 2005

18. SC3 GOALS Service Challenge 1 (end of 2004): Demonstrate the possibility of throughput of 500 MByte/s to Tier1 in LCG environment. Service Challenge 2 (spring 2005): Maintain the throughput 500 MByte/s cumulative on all Tier1s for prolonged time, and evaluate the data transfer environment on Tier0 и Tier1s. Service Challenge 3 (Summer-end of 2005) Show reliable and stable data transfer on each Tier1: to disk -150 MByte/s, to tape - 60 MByte/s. All Tier1s and some Tier2s involved. Service Challenge 4 (Spring 2006): Prove the GRID infrastructure performance to handle the LHC data in proposed rate (from raw data transfer up to final analysis) with all Tier1s and majority of Tier2s. Final Goal: Build the production GRID-infrastructure on all Tier0, Tier1 и Tier2 according to the LHC experiments specifics.

19. Summary of Tier0/1/2 Roles Tier0 (CERN): safe keeping of RAW data (first copy); first pass reconstruction, distribution of RAW data and reconstruction output to Tier1; reprocessing of data during LHC down-times; Tier1 : safe keeping of a proportional share of RAW and reconstructed data; large scale reprocessing and safe keeping of corresponding output; distribution of data products to Tier2s and safe keeping of a share of simulated data produced at these Tier2s; Tier2 : Handling analysis requirements and proportional share of simulated event production and reconstruction. No long term data storage.

20. Tier2 Roles Tier2 roles vary by experiment, but include: –Production of simulated data; –Production of calibration constants; –Active role in [end-user] analysis  Must also consider services offered to T2s by T1s –e.g. safe-guarding of simulation output; –Delivery of analysis input. No fixed dependency between a given T2 and T1

21. A Simple T2 Model Each T2 is configured to upload MC data to and download data via a given T1 In case the T1 is logical unavailable, wait and retry For data download, retrieve via alternate route / T1

24. Universal Grid infrastructure in University Center of JINR Grid infrastructure is set of virtual machines (VMs) running on physical ones (hosts) Virtualisation was made using User Mode Linux current number of VMs is 36 (6 VMs on each of 6 hosts) all virtual resourses are grouped into independent testbeds which in turn can be used for different aims: system administrators and users training in grid field, debugging and testing custom grid services in desirable grid environment ● Course for system administrators using Nordugrid ARC middleware was successfully conducted on that infrastructure ● LCG2 or gLite installation and configuration course is in future plans
