by LRZ aktuell Nov. 23, 2011

Nov. 23, 2011

Dear users of the Supercomputer and other HPC systems at LRZ, With view on the installation of the next-generation Petaflop-class system SuperMUC at LRZ, a workshop covering the programming environment of this system will start on December 5, 2011 (10:00) in the lecture room H.E.009 in the LRZ building. The first three days are comprised of a comprehensive coverage of Intel s software stack, followed by talks on IBM-specific extensions and software packages (e.g., the LoadLeveler batch scheduler). Please consult http://www.lrz.de/services/compute/ courses/#SuperMUCIntro for details.

PRACE awards 91 million processor core hours on the DECI call to 35 projects, new call open
by LRZ aktuell Nov. 23, 2011

Nov. 23, 2011

PRACE Press Releases PRACE awards 91 million processor core hours on the DECI call to 35 projects, new call open 23 November 2011 Europe's HPC infrastructure PRACE, the Partnership for Advanced Computing in Europe, announced that 35 projects, selected from 54 proposals, will share 91 million processor core hours awarded by the most recent DECI (Distributed European Computing Initiative) call. The consortia of European computational scientists whose projects were selected for funding will be given access to one of the 19 European national HPC services through a national HPC resource exchange initiative, operated by members of the PRACE association. The successful projects will be led by researchers from 19 European countries with collaborators from the USA and Canada. The call was oversubscribed by more than a factor of 2.5. Due to the excellent quality of the proposals, the contributing partners increased the resources offered to the call by 11% over the original commitment, however this still meant that many good projects could not be granted resources. Projects are given access to compute resources at one or more of Europe's national supercomputers. For the first time in seven years of DECI calls, national supercomputers in Poland, Bulgaria and Ireland, in addition to national supercomputers in Germany, UK, France, Italy, Spain, the Netherlands, Finland and Sweden, are participating in the HPC resource exchange initiative. The increase in number of national HPC facilities means that it has been possible to provide 55% more resources, on average, to each project as compared to the last DECI call. Successful projects are chosen for their potential to achieve ground-breaking scientific results through the use of supercomputers. The DECI support team provides specialist applications support to adapt the scientific codes to the most appropriate architecture. The following thirty-five projects, in alphabetical order, were awarded access to PRACE RI resources: * NR-NSNS-BHNS (Accurate Gravitational Waves from Unequal Mass Compact Binaries and their Tidal Signatures), Bernd Bruegmann, Universitaet of Jena, Germany * BlackHoles, Vitor Cardoso, Instituto Superior Tecnico, Portugal * ARTHUS-3, Hans-Thomas Janka, Max-Planck-Institute for Astrophysik, Germany * Planck-LFI, Hannu Kurki-Suonio, University of Helsinki, Finland * MAESTRO (Magnetized Accretion and Ejection phenomena in astrophysics), Dr. Claudio Zanni, Department Osservatorio Astronomico di Torino, INAF, Italy * SMARC (Solar Magnetically Active Region Corona), Dr. Peter Hardi, Max Planck Institute for Solar System Research, Germany * PETAHUB (The Phase diagram of the Hubbard model by quantum Monte Carlo and Petaflop supercomputers), Sandro Sorealla, International School for Advanced Studies, SISSA, Italy * PICKH, Dr. Pierre Henri, Katholieke Universiteit Leuven, Belgium * SCW, Marco Masia, Universita' di Sassari, Italy * SIVE-2, Prof. Erik Lindahl, Royal Institute of Technology, Sweden * LASIPROD (LArge scale molecular SImulations of PROtein - DNA recognition in the combinatorial control of transcription), Dr. Vlad Cojocaru, Max Planck Institute for Molecular Biomedicine, Germany * VIRonSAMs, Prof. Michele Cascella, Universitat Bern, Switzerland * LGICTAMD, Dr. Grazia Cottone, University of Palermo, Italy * TanGrin, Vesa Hytoenen, University of Tampere, Finland * HELIXKINETICS, Dr. Robert Best, University of Cambridge, UK * NANOBIO-2, Niall English, University College Dublin, Ireland * PHOTMAT, Dr. Manthos G.

The computing resources for this call are available from May 2012 to April 2013. The new call features additional Tier-1 systems with new computing architectures. Around 100 million core hours will be available to applicants. The call will close on 10th of January, 2012.

Upd:Router csr1-0gz laeuft wieder
by LRZ aktuell Nov. 23, 2011

Nov. 23, 2011

Aenderungen an der Mitteilung: Update Der Router csr1-0gz funktioniert wieder. Er war (wahrscheinlich durch ein Hardwareproblem) vollstaendig abgestuerzt. Durch den Router-Crash haben wir auch ein Problem im BGP-Routing aufgedeckt. Routen die mit 141.84... , 192.68.212... und 192.68.213... beginnen wurden nicht mehr an unseren Internet-Provider annonciert. Dadurch waren auch Netze vom Ausfall betroffen die nicht am csr1-0gz haengen. Diese Information finden Sie im WWW unter http://www.lrz-muenchen.de/services/netz/aktuell/ali4166/ Wolfgang Beyer

Upd:TSM usage on SuperMIG: Bug resolved
by LRZ aktuell Nov. 22, 2011

Nov. 22, 2011

Changes to this message: Bug fix available Update (Nov. 22, 2011): We have installed a pre-release (i.e. Beta) update to the software which again allows to recursively perform archivation, solving the problem described below. Please report to us if this software release does not perform for you as expected. The final release of the TSM update will become available end of December. ----------------------------------------------------------------------- Currently on SuperMIG a problem with archiving and backup exists. The command for recursively archiving directories (e.i., the -subdir option) does not work. Instead of using dsmc ar -subdir=yes ./mydirectory please use the following workaround until the bug is fixed, find ./mydirectory > filelist.txt dsmc ar filelist=filelist.txt IBM is informed and is working on a solution.
