DataTAG Work Package 4 Meeting Bologna Simone Ludwig Brunel University 23rd and 24th of May 2002

2 Overview UK Testbed Activities Software Releases Status Overview Testbed at RAL Further Activities PPARC Effort in WP4 DataTAG Work done so far Work Plan

3 Software Releases Deployment largely driven/limited by EDG software release status and cycles 3 major releases with three yearly Testbeds 1, 2 and 3 Minor releases every 2 months, and then patch level releases between those Currently there is a mixture of sites with: –some version of the Globus gatekeeper –old Globus installations –Globus 2.0/2.0beta installations, including EDG installations (using 2.0beta), usually just a Computing Element BaBar installations of EDG CE

5 Testbed at RAL Hardware Purchase installed March 156 Dual 1.4GHz 1GB RAM, 30GB disks (312 cpus) 26 Disk servers (Dual 1.266GHz) 1.9TB disk each Expand the capacity of the tape robot by 35TB Current EDG TB setup 14 Dual 1GHz PIII, 500MB RAM 40GB disks Compute Element (CE) Storage Element (SE) User Interfaces (UI) Information Node (IN) + Worker Nodes (WN) + Existing Central Facilities (Non Grid) 250 CPUs 10TB Disk 35TB Tape (Capacity 330 TB)

6 Further Activities Testbed 1.2 Integration started last week TB2.0 September 2002 –Several major releases of software due TB3.0 March 2003 –First feasible release using OGSA –Even if early adopters start now EDG already adopted by other Grids –Pressure to expand testbeds or integrate with others –DataTAG, CrossGrid, GLUE

7 PPARC Effort in WP4 DataTAG Involved in 4.1: Networked Resource Discovery Systems - Service Discovery 4.3: Interworking between domain- specific collective Grid services - Interoperability

8 Work done so far Induction to Grid technologies Development and Installation of GLOBUS Grid Lab Environment Analysis of Grid services Review of Analysis, Modelling and Reverse- engineering tools Investigating of Schema notations Investigation of different Resource Discovery Systems (Jini, SDS, LDAP)

9 Work Plan Investigation of various experiments (CMS, BaBar) in order to find requirements necessary for Grid operation -> Service Discovery Investigation of Web Service Technology to get an idea of a common framework Definition of a Common Framework in which interfaces and protocols can be specified and modelled (-> Interoperability) Development of Test Cases to verify and validate the interoperability issues
