Upd:Update: 10th Tuning Workshop of the Virtual Institute - High Productivity Supercomputing (VI-HPS)
by LRZ aktuell Oct. 10, 2012

Oct. 10, 2012

Changes to this message: Update Please accept our apologies if you encountered problems registering for the 10th VI-HPS Tuning Workshop which will take place at LRZ in Garching next week, 16-19 October 2012. Places are still available, and registration has been extended to Friday 12th October. Agenda and further information at http://www.vi-hps.org/vi-hps-tw10/ "The 9th VI-HPS Tuning Workshop was quite a boost for me in my work to optimize [our] main application, which is a hybrid MPI + OpenMP parallel code." -- previous workshop participant Original message: ********************************************************************* 10th Tuning Workshop of the Virtual Institute - High Productivity Supercomputing (VI-HPS) at Leibniz Rechenzentrum (LRZ), Garching-bei-Muenchen, Germany 16-19 October 2012 http:/www.vi-hps.org/ vi-hps-tw10/ ********************************************************** *********** To help improve the quality and accelerate the development process of complex simulation codes in science and engineering, the VI-HPS Virtual Institute - High Productivity Supercomputing develops tools for checking the correctness and analyzing the performance of parallel applications. Emphasis is given to the programming models MPI & OpenMP. This workshop organized by VI-HPS for Gauss Centre for Supercomputing PRACE Advanced Training Centre will: * give an overview of our programming tools suite * explain the functionality of individual tools, and how to use them effectively * offer hands-on experience and expert assistance using the tools Tools which will be covered include Kcachegrind, MAQAO, PAPI, Periscope, Scalasca, TAU, Vampir and Score-P. The workshop will be held in English and runs from 09:00 to not later than 18:00 each day, with breaks for lunch and refreshments. There is no fee for participation, however, participants are responsible for their own travel and accommodation arrangements. Classroom capacity is limited, therefore priority will be given to applicants with parallel codes already running on the LRZ IBM SuperMUC & SuperMIG, and those bringing codes from similar systems to work on. Participants are therefore strongly encouraged to prepare their own MPI, OpenMP and hybrid MPI+OpenMP parallel application codes for analysis.

Upd:MPP Cluster: Returned to user operation
by LRZ aktuell Oct. 9, 2012

Oct. 9, 2012

Changes to this message: Returned to user operation The MPP cluster has been returned to user operation after a rather over-extended maintenance; apart from difficulties with integrating the new hardware there also was some fallout from the recent power interruption which required more extended repairs than expected. Note that login presently only works via lxlogin1.lrz.de. The second login node is presently not yet available. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/aktuell/ali4403/ Reinhold Bader

Upd:OWA-Sicherheitsluecke behoben - Vorschau fuer Dateianhaenge wieder moeglich
by LRZ aktuell Oct. 8, 2012

Oct. 8, 2012

Aenderungen an der Mitteilung: Sicherheitsluecke behoben - Einschraenkung aufgehoben Update am 08.10.2012:Microsoft hat die unten beschriebene Sicherheitsluecke inzwischen gefixt und wir haben nach Einspielen des entsprechenden Updates die Funktion "Als Webseite oeffnen" wieder aktiviert. ----------------------------------------------------------------------- Aufgrund einer gestern (25.07.2012) bekannt gewordenen Sicherheitsluecke in Exchange haben wir wie von Microsoft empfohlen die Vorschau fuer Dateianhaenge in Outlook Web App (OWA) deaktiviert. Das bedeutet, dass z.B. bei PDF- oder Word-Dokumenten keine integrierte Vorschau mehr moeglich ist, sondern diese Dokumente nur mit einer geeigneten Applikation betrachtet werden koennen. Es entfaellt also die bisherige Funktion "Als Webseite oeffnen". Wir sind uns bewusst, dass die Deaktivierung der Vorschaufunktion das Arbeiten unbequemer macht, halten die Massnahme aber aus Sicherheitsgruenden fuer absolut notwendig. Detaillierte Informationen zu der Sicherheitsluecke finden Sie im Heise-Newsticker in der Meldung Microsoft warnt vor Oracle-Luecken in Exchange und Sharepoint http://www.heise.de/newsticker/meldung/ Microsoft-warnt-vor-Oracle-Luecken-in-Exchange-und-Sharepoint-1652251.html Diese Information finden Sie im WWW unter http://www.lrz-muenchen.de/aktuell/ali4370/ Ado Haarer

Upd:MPP Cluster: Interruption of services
by LRZ aktuell Oct. 4, 2012

Oct. 4, 2012

Changes to this message: Prolongation of maintenance 2nd Update (October 4, 15:45): Due to unforeseen problems with the electrical infrastructure, return to user operation will be delayed, probably to early next week. We'll keep you up-to-date with the status of the cluster via this URL. ----------------------------------------------------------------------- Dear users of the MEGWare MPP cluster at LRZ, due to an extended hardware and software maintenance, the MPP cluster will not be available for user operation between September 24, 8:00 and October 4, 17:00. SLURM batch processing will be suspended on September 24 in order to drain the system before the interruption starts. Part of the maintenance time indicated above is also dedicated for energy measurements on the system. The other cluster segments are not impacted by this maintenance.

Upd:SuperMUC fully available again
by LRZ aktuell Oct. 3, 2012

Oct. 3, 2012

Changes to this message: Update 5th Update (Oct 3, 12:50) The cause of the GPFS failure on Saturday, Sep 29 has been identified as a software problem triggered by data migration to additionally installed disk space. After performing the data migration in offline mode, the system has now been returned to normal user operation again. Please produce a new login shell to properly set the SCRATCH and WORK environment variables in order to access the GPFS data from the login nodes. Submission of LoadLeveler jobs that use GPFS should now also work again.
