H H PPP CCC UK NATIONAL HPC SERVICE H H P P C C -------------------------- HHHHH PPP C x x EPCC and CCLRC Daresbury H H P C C xx Laboratory are members of H H P CCC x x the HPC-UK partnership ---------------------------------------------------------------------- HPCx User Mailing 100 30 June 2006 ---------------------------------------------------------------------- Contents ** Closure of CSAR ** Supercomputing resources across Europe available to UK researchers ---------------------------------------------------------------------- Greetings-- CLOSURE OF CSAR Today is the last day of the CSAR service. Once again, our very best wishes to everyone who has contributed to the success of the service. Over the years I think both we and they have learned a lot from each other's work. This is the basis of the UK-HPC partnership within which we and our colleagues in Manchester will continue to collaborate. A warm welcome to those people who will now be moving their work to HPCx, especially those who have joined us since last week. Transfer of unused time from CSAR to HPCx ----------------------------------------- If you worked on CSAR and now have a project on HPCx, any time your project has unused when CSAR closes will be transferred to HPCx. Previously the intention was to transfer only time which you had intended to use after the closure of CSAR, but EPSRC has now changed this policy - ALL remaining time will now be transferred. Time will be converted from Newton and Green CPU Hours to HPCx AUs. The conversion rate is based on the Linpack ratings for the two machines. Projects which so far have existed on both services --------------------------------------------------- The time left unused on CSAR will be added to your HPCx project as soon as possible after the service closes; if all goes well, next week. Projects which are being moved from CSAR to HPCx ------------------------------------------------ Your HPCx projects have now been created. I allocated the same amount of time as your CSAR profile indicated you were planning to use after July 1. It will be adjusted once we know how much time you have left on CSAR when the service closes. Once again, this will done as soon as possible after the service closes. Registering on HPCx ------------------- Everything about accounts, projects, resource allocation and so on can be found in the Admin FAQ, which is here: http://www.hpcx.ac.uk/projects/FAQ/ It really is worth having a look at this. Getting started --------------- The HPCx User Guide is here: http://www.hpcx.ac.uk/support/documentation/UserGuide/HPCxuser/HPCxuser.html Course material for the "Porting Codes form CSAR to HPCx" course, which CSAR and HPCx ran together, can be found here: http://www.hpcx.ac.uk/support/training/HPCxCSARPorting.html Moving your files from CSAR to HPCx ----------------------------------- From tomorrow, you won't be able to run jobs on the CSAR systems. However, for a while you will still be able to log in in order to take your files away. We suggest you do this as soon as you can. Two useful sources of information about this: Materials from the "Data Migration" lecture in the porting course: http://www.hpcx.ac.uk/support/training/HPCxCSARPorting/L05-DataMigration.pdf An HPCx Technical Note: "Transferring large files to and from HPCx": http://www.hpcx.ac.uk/research/hpc/technical_reports/HPCxTR0603.pdf The helpdesk ------------ Please email to: support@hpcx.ac.uk ---------------------------------------------------------------------- SUPERCOMPUTING RESOURCES ACROSS EUROPE AVAILABLE TO UK RESEARCHERS The DEISA project is a consortium of major national HPC centres which operates an integrated infrastructure over eleven existing national high-end platforms across Europe. HPCx has recently joined the DEISA supercomputing Grid. DEISA (Distributed European Infrastructure for Supercomputing Applications) is funded by the EU and has access to a large amount of CPU time on these systems - on HPCx, for example, 5% of the total time is reserved for this. All this time is available for researchers to use. You can apply for this time under the DEISA Extreme Computing Initiative (DECI). Under the first call for proposals, projects were accepted with individual CPU requirements of up to several hundreds of thousands of CPU hours. The deadline for the second call is July 15th 2006. We feel that this could be a major benefit for researchers in the UK, and we would like to encourage you to take advantage of this opportunity. For details on how to apply see http://www.deisa.eu/applications/. If you would like help or advice in preparing your proposal, please feel free to contact the HPCx Support Team .
