11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke Global HPC migration

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke These applications generate Grid like distributed computing requirements: Massive & Dynamic resources for compute and store – leading to registration and discovery requirements Federation of heterogeneous systems Federation of many disparate data and meta data Access for many widespread “loosely connected” users with a “standard” credential Replication management Secure virtual systems (“VPGs”) On demand access to vast compute power Inter resource accounting Agreements……………..

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke So … What is a GRID … many things to many people…. Federation of Clusters Virtualisation of computing Heterogeneity Discovery Standards …

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke Power: 110V AC 60Hz Computing: ? ? At the highest level it is computing coming out of a wall socket….

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke Leads to need for GRID middleware to mediate all this : Application Authentication Resource Information Resource Allocation Data access Metadata cataloguing GRID middleware Authorisation Network protocols& services CPU schedulers Mass storage access Resource specific services

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke Network Today: Virtual Private Network (VPN): Virtualises Network connection between sites Makes enterprise think it owns a dedicated secure connection Virtualisation

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke The Grid Tomorrow: Virtual Private Grid (VPG): Virtualises Computing, Storage and Network connection between sites Makes enterprise think it owns a dedicated secure computer system

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke The Grid Next Year: Virtual Private Services ???: Everything built from robust, interacting secure services provided by trusted GridCos Service

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke A word on interoperability and Standards Grids will not work by adapting each grid to talk to another. Or adopting the same bespoke software. Grids will work by defining and agreeing standards in analogy with the internet This is the Goal of the Global Grid Forum – it’s a long and hard job

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke Where can you go and use a Grid

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke Some Grid Testbeds The UK e-Science Grid UK Particle Physics Testbed (GridPP) The European DataGrid Testbed

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke EGEE  will bind national infrastructures - focussing all activities towards establishing a production quality Grid for Europe EGEE A production Europe Grid for An EU Flagship Project Starting Now

11-Feb-2004 IoP Half Day Meeting: Getting Ready For the Grid Peter Clarke Concluding Remarks Grids are an evolution which was waiting to happen Grids are about seamless discovery and use of heterogeneous resources around the globe Grids are about standards for interoperation, just as the internet only works because of standards Grids are about “virtualising” Computing just as a “VPN” virtualised a leased line Grids are set to evolve to a Web-Services framework – where everything is just a set of self describing, discoverable, interoperating services
