Gheller and G. Fiameni, CINECA (Bologna, Italy) Data represent an emerging issue for scientists. Experimental and observational instruments produce enormous quantities of images and information. Computers and numerical simulations generate huge amount of data. All these data must be stored, managed and analysed. These steps require a great human effort, large scale facilities and efficient, powerful tools. The first step of this process, is the possibility of accessing data, stored in a distributed, heterogeneous environment. This requires enabling tools which are able to manage large distributed dataset and data archives and that support efficient access to data, by means of effective services and protocols, often acting at the server side, avoiding large and slow data movement. We present the solution that the HPC-Europa consortium is developing, using different technological solutions, like SRB and OGSA-DAI and we show the present status of implementation of a data portal for theoretical astrophysical data. You are invited to take part this event through your nearest Access Grid node. If you wish to take part, please email to the HPCx helpdesk: support@hpcx.ac.uk. We will then send you the necessary technical details to join the meeting.

This Workshop is now established as a leading national event dedicated to distributed high performance scientific computing. The principle objective is to encourage close contact between the research communities from the Mathematics, Chemistry, Physics and Materials Programmes of EPSRC and the major vendors of workstations, software and peripherals. You are invited to attend this year's workshop, which will have a format similar to that of previous years with about a dozen major vendors making 20-minute presentations on topics such as hardware, compilers, graphics, storage, networking etc. In past years the audience has been very appreciative of the technical content of these talks and we have encouraged the speakers nominated by the vendors to focus their presentations accordingly. Important components of the workshop include the availability of systems for benchmarking evaluation purposes, plus the exhibition itself. Vendors are providing Internet access to these systems prior to the event, and the availability of products on the day will help delegates evaluate the machines. We hope to make loaned systems available from the 4th December for the duration of the event. For further details, and to register, please go here: http://www.cse.clrc.ac.uk/disco/mew17/mew17.html
