Infrastructure areas

• Middleware – deployment

- development

• Computer resources (incl hardware)

• Networking

UK Level 2 Grid

• Assumptions that people only run on Linux built into Globus and much Particle Physics Grid

• May go away with Java based systems • Difficult to get uniform policies for accounts,

firewalls.• UK <-> Japan experience, very heterogeneous

Grid, need to establish CA• Robert Allan, Stephen Pickles UK contact• Yoshio Tanaka – Japan contact

Lessons from UK Grid

• Importance of monitoring health of Grid. State of the Grid is displayed on a web site.

• Need to get firewall policy agreed, opening agreed ranges of ports.

• Action: send Level 2 Grid test suite to ApGrid and NaReGi

• Exchange documents and draft policy proposals to Production Grids RG

Middleware Development

• NaReGi SuperScheduler to be exchanged with UK scheduling developments.

• Aim is to get a unified approach so that components are interoperable.

• Japan – NaReGi WP 1UK – GRIP/EuroGrid brokerUK has common currency for resource but details

of costing is different at different sites.Grid economics – Markets project in UK Business Grid/ ASP portal Japan.

Development Actions

• Exchange information and personnel NaReGi WP1 and UK Markets Project and EuroGrid/GRIP.

• UK Contact Dave Snelling, Jon MacLaren

• Japan Satoshi Itoh, Kento Aida (TiTech)

• Invite Japanese colleagues to UK Scheduling Meeting 21/22 October, then visit FLE

Transport

• Test IP and MPI between Japan and UK, latency aware MPI

• PACX-MPI and GRID-MPI collaborations.• Applications experiments with DEISA partners.• Linking in optical networks

Tokyo/Chicago/Europe via StarLink 2.4 Gps demo for SC2004

• David Henty, Neil Stringfellow – Yutaka Ishikawa, Hiroshi Takemiya (GRID MPI)

• Satoshi Sekiguchi – Peter Clarke (Networking)

IPv6 Issues

• 12-18 months UK and Japan work together at the GGF IPv6 Research Group.

• Out of this should come some experiments between UK and Japan, using GT2 and/or UPL

Grid VM

• Japan contact Professor Kohno Univ Electric Communications.

• What might be the usage of this, sandbox capability, exposing Grid services as OS?

• Who is the UK contact? Dave Snelling and Satoshi Sekiguchi and Satoshi Matsuoka will monitor this.
