These are described in the sections below. Together these events will make up a really important opportunity for contact between users, vendors and providers of high-performance computing in the UK. You are most cordially invited to attend, and HPCx and DL staff look forward to meeting you at Daresbury. How to get to the Daresbury Laboratory: http://www.cclrc.ac.uk/Activity/ACTIVITY=DLMaps; Hotels in the area: http://www.cse.clrc.ac.uk/disco/mew14/hotels.html ---------------------------------------------------------------------- HPCx COURSE: OPTIMISATION TECHNIQUES FOR THE POWER4 PROCESSOR Tuesday, 9 December. This course will focus on tools and techniques for single processor optimisation on HPCx. The course will cover the architecture of the processors and memory system, profiling and hardware counter tools, getting the best from the compilers and Power4-specific tips and tricks. There will be hands-on sessions in addition to lecture material. Details and registration form: http://www.hpcx.ac.uk/support/training ---------------------------------------------------------------------- HPCx SEMINAR: TOWARDS CAPABILITY COMPUTING Wednesday, 10 December One of our key challenges is to ensure that the full capability of the HPCx service is used to the limit. We need to enable applications in all disciplines to scale effectively right up to the full size of the system. Speakers will include experienced users and HPCx and IBM staff. This will be the first in an annual series of seminars. http://www.hpcx.ac.uk/about/events/annual2003/ ---------------------------------------------------------------------- HPCx USERS' GROUP MEETING 16:30, Wednesday, 10 December This is a chance for users to bring their concerns and problems directly to the senior management of HPCx, who will be present. We hope that this will also include issues that have arisen during the Seminar. Our intention is that in many cases it will be possible to take decisions on the spot to respond to these. There will also be an update from IBM on plans for the Phase 2 upgrade. ---------------------------------------------------------------------- 14TH DARESBURY MACHINE EVALUATION WORKSHOP Thursday-Friday, 11-12 December This well-established and widely-respected annual event aims to encourage close contact between the research communities and vendors of distributed high-performance scientific computing. About a dozen vendors are expected to make presentations. Systems will be available for benchmarking (it is hoped starting on Monday, 8 December), and there will be an exhibition. Proceedings will be published and made available to those registered to attend. http://www.cse.clrc.ac.uk/disco/mew14.shtml ---------------------------------------------------------------------- TECHNICAL REPORTS A reminder that the following page contains links to a number of papers by HPCx staff and others which may be useful for users: http://www.hpcx.ac.uk/research/hpc/index.html In particular, the following technical reports are now available - the last two are recent additions. * "Capability Computing: Achieving Scalability on over 1000 Processors", Joachim Hein and Mark Bull. * "Performance of the Turbulence Code", Joachim Hein. * "3D FFTs on HPCx (IBM vs FFTW)", Adrian Jackson, Gavin J. Pringle. * "Investigating MPI-IO on HPCx", Elena Breitmoser. * "Single sided communications on HPCx", Adrian Jackson. * "File I/O from multi processor jobs", Joachim Hein * "Using the Hardware Performance Monitor Toolkit on HPCx", Joachim Hein * "Exchanging multiple massages via MPI", Joachim Hein, Stephen Booth, Mark Bull ---------------------------------------------------------------------- SUPERCOMPUTING 2003 SC03, the fifteenth in the annual Supercomputing Conference series, will take place in Phoenix, Arizona on 15-21 November. EPCC and DL will have adjacent stands, and together they will provide an HPCx presence. If you attend, you can find us at booths 3417 and 3421. ---------------------------------------------------------------------- Regards --John ---------------------------------------------------------------------- Earlier mailings: http://www.hpcx.ac.uk/support/notices/index.html To be removed from the mailing list: log into your website account, go to the "Update" page, and click the "Opt out of user emails" field; then click "Commit update". -- John Fisher j.fisher@epcc.ed.ac.uk HPCx User Administration and Helpdesk HPCx: http://www.hpcx.ac.uk Helpdesk: support@hpcx.ac.uk Phone: +44 131 650 5029 Fax: +44 131 650 6555
