Oct. 4, 2019

Dear HPC users of LRZ, There are still free places for the following new workshops and courses at LRZ: Intel Artificial Intelligence Workshop: AI From the Data Center to the Edge Date: Tuesday, October 15, 2019, 09:00-17:00 Location: LRZ Registration deadline: October 8, 2019 (extended!) Lecturers: Intel expert trainers: Vishnu Madhu (technical consultant engineer), Jai Sharma (student ambassador program in Germany/UK, Intel DevMesh program) Further information and registration: https://www.lrz.de/services/compute/courses/2019-10-15_hiai1w19/ Topics: In this event, Intel will be offering an End to End AI workshop, covering topics on Machine Learning, Deep Learning, as well as the Intel AI DevCloud and optimized frameworks and tools. The workshop will be led by the Intel experts, and will walk through cases of how students can use Intel & AI for their own projects. Performance Portability Programming with Kokkos Date: Thursday, October 24, 2019, 09:00-17:00 Location: LRZ Registration deadline: October 14, 2019 Lecturers: Christian R. Trott (Sandia National Lab, USA) Further information and registration: https://www.lrz.de/services/compute/courses/2019-10-24_hkok1w19/ Topics: The Kokkos C++ library enables applications and domain libraries to achieve performance portability on diverse many-core architectures by unifying abstractions for both fine-grain data parallelism and memory access patterns. In this tutorial we describe Kokkos' abstractions, summarize its application programmer interface (API), present performance results for unit-test kernels and mini-applications, and outline an incremental strategy for migrating legacy C++ codes to Kokkos.

ANSYS CFD Course and ANSYS Technology Day @ LRZ
by Weinberg, Volker Aug. 12, 2019

Aug. 12, 2019

Dear LRZ users, we want to point your attention to the following 2 ANSYS related events at LRZ: LRZ course on "Introduction to ANSYS Fluid Dynamics (CFX, Fluent) on LRZ HPC Systems" In the week 2-6 September 2019 the successful LRZ course "ANSYS Fluid Dynamics on LRZ HPC Systems" providing a systematic introduction to the ANSYS CFX and ANSYS Fluent software systems as well as into their efficient application in a HPC environment at LRZ will be held for the 2nd time. Hereby we would like to inform you, that with currently 17 registered participants it is now already guaranteed that the course will take place and that there are currently still open seats in the computer class room available. Further registration for this introductory course on practical ANSYS CFD and HPC is still possible for interested participants until 19 August 2019. In particular we are proud to present our guest speaker Dr. Barbara Neuhierl, Manager CFD Business Development @ CADFEM GmbH, Grafing, who will give in the CADFEM session on Wednesday afternoon (4 September 2019) a short overview and introduction about meshing capabilities in the most recent version(s) of ANSYS Fluent Meshing. Her presentation will include a practical hands-on session for meshing and simulation of the flow through an example component using ANSYS Fluent Meshing. Furthermore the course provides deep insides in systematic CFD setup and CFD methodology up to fully automated parametric, mesh and model variations by using Python-scripted ANSYS CFX and ANSYS Fluent simulation and postprocessing workflows. A more detailed agenda of the course and the link to the registration page are available on the website: https://www.lrz.de/services/compute/courses/2019-09-02_hcfd2s19/ <https://www.lrz.de/services/compute/courses/2019-09-02_hcfd2s19/> Joint ANSYS Technology Day by LRZ and CADFEM GmbH On the occasion of the new 2019 R3 release of the ANSYS software, the LRZ, Garching near Munich and CADFEM GmbH, Grafing jointly present and organize an ANSYS Technology Day on Wednesday, 6 November 2019 at LRZ. The focus of this ANSYS Technology Day will be set primarily for ANSYS Mechanical and the following topics will be highlighted: * Introduction & Welcome * Selection of Update Highlights with focus on ANSYS Workbench and ANSYS Mechanical * Working with faceted bodies from topology optimization or 3D scans * User-defined results in ANSYS Mechanical for result evaluations with special requirements * Introduction to LRZ HPC Systems and ANSYS Software on LRZ Linux Clusters and Supercomputers * Discussion, questions and answers. During the final discussion and Q&A round you potentially may want to discuss your specific computational needs, your simulation requirements using ANSYS software at the LRZ facilities, your particular ANSYS model or your simulation idea with us. All this can be discussed together with the LRZ and CADFEM lecturers and with the participants of the ANSYS Technology Day. To enable this on a higher level, please feel free to contact Dr. Cord Steinbeck-Behrens (csb(a)cadfem.de<mailto:csb@cadfem.de>) and/or Dr. Thomas Frank (Thomas.Frank(a)lrz.de<mailto:Thomas.Frank@lrz.de>) in advance with your particular questions or points of interest and with the possibility to provide your ANSYS CSM/CFD model to them. After the lecture program at the ANSYS Technology Day the LRZ is offering the possibility of a guided tour to the LRZ computer building featuring the new SuperMUC-NG supercomputer, which is ranked in the new TOP500 list (June 2019) of world's fastest supercomputers on rank number 9 and which is thereby the fastest supercomputer of all EU member states. Timely registration is mandatory for participants who are interested in the guided SuperMUC-NG tour. The guided tour will start at approx. 4:00 pm and will last for approx. 1 hour. More details about the ANSYS Technology Day and the link to the registration page are available on the website: https://www.lrz.de/services/compute/courses/2019-11-06_hatt1w19/ Please also pass this announcement to other interested colleagues.

BEENDET: Notfall-Wartung csr1-1mf (KATUM), Reboot
by Bernhard Schmidt Aug. 5, 2019

Aug. 5, 2019

--- Update 12:35 --- Nach dem Reboot einer Linecard des betroffenen Routers sieht es jetzt aus unserer Sicht wieder gut aus. Bitte melden Sie, wenn Sie noch Störungen bemerken. --- Erstmeldung --- Aufgrund von unklaren Problemen mit Nutzerverkehr nach außerhalb des MWN nach der Störung am Freitag abend muss JETZT der zweite Campusrouter für Garching neu gestartet werden. Die meisten Nutzer sollten keinen Ausfall bemerken, da ihre Standorte redundant am Maschinenwesen angebunden sind.

BEHOBEN: Großflächige Störung LAN/WLAN Bereich Innenstadt
by Bernhard Schmidt July 30, 2019

July 30, 2019

=== Update 30.7.2019 12:15 === Der Stromausfall wurde behoben. Er trat durch die Arbeiten einer Fremdfirma an der Stromverteilung im TUM Stammgelände auf, in deren Folge mehrere Sicherungen auch hinter den USVs gefallen sind. Dadurch waren teilweise auch Komponenten mit mehreren Netzteilen ausgefallen. Wir prüfen, ob die Stromversorgung oder -verteilung in diesem Standort verbessert werden kann. === Erstmeldung 30.7.2019 11:56 === aufgrund einer Störung an einem Router im TUM-Stammgelände stehen derzeit folgende Standorte nicht zur Verfügung D* LMU Theresienstr. 37-41 T* Innenstadtkliniken SG Giselastr. 10 ZT Zentnerstr. 31 YA Schellingstr. 33 Z5 SWH Adelheidstr. 13 Z4 SWH Kreittmayerstr.
