Doppelerfolg beim Deutschen Rechenzentrumspreis
Das Leibniz-Rechenzentrum (LRZ) war beim Deutschen Rechenzentrumspreis doppelt erfolgreich: In der Kategorie "Datacenter Klimatisierung und Kühlung" konnte das LRZ mit zwei Lösungen aus dem Bereich der Wasserkühlung punkten und gemeinsam mit den Partnern Fahrenheit und MEGWARE die Plätze 1 und 2 für sich verbuchen. Das LRZ setzte sich damit in der meistumkämpften Kategorie beim diesjährigen Wettbewerb mit insgesamt 51 Einreichungen durch. Fahrenheit und Megware haben für das LRZ Lösungen entwickelt, mit denen sich deutlich effizienter kühlen lässt und die die bestehenden Wasserkühltechnologien ergänzen und weiterentwickeln. Bei Fahrenheit handelt es sich um ein Adsorptionskühlsystem zur Nutzung der Rechnerabwärme. Dies wird z.B. eingesetzt beim künftigen nationalen Höchstleistungsrechner SuperMUC-NG (Next Generation). CoolMUC-3, realisiert von Megware, überzeugte mit seiner 100% Warmwasserkühlung auch von Komponenten wie Switches oder Netzteilen.

LRZ Mitglied im VI-HPS
Seit April 2018 ist das Leibniz-Rechenzentrum (LRZ) offizielles Mitglied des Virtual Institutes – High Productivity Supercomputing (VI-HPS). Das VI-HPS Konsortium hat sich zum Ziel gesetzt, Entwicklern von komplexen Simulationscodes Werkzeuge an die Hand zu geben, mit denen die Codes auf ihre Qualität überprüft werden können und Wege aufgezeigt werden, um die Leistungsfähigkeit kontinuierlich zu steigern. Mit seiner Mitgliedschaft möchte das LRZ seinen Beitrag in dieser Community weiter steigern und seine Expertise noch aktiver einbringen. Derzeit fokussieren die LRZ-Aktivitäten vorrangig auf das Tool “Callgrind”, das seit kurzem am LRZ gepflegt und weiterentwickelt wird. Callgrind hilft insbesondere, Flaschenhälse beim Zugriff auf Daten zu identifizieren und zu beseitigen. Die beliebten Workshops und Trainings in diesem Bereich, wie z.B. die Ausrichtung der VI-HPS "Tuning Workshops", bietet das LRZ natürlich weiterhin an.

New Course: Introduction to GASPI - Scalability in HPC
There are still free places available for the upcoming GASPI Workshop @ LRZ. The registration deadline has been extended until Friday, 4 May 2018. Don't miss this chance!
- The GASPI programming model represents a powerful and highly scalable alternative to the one-sided communication of MPI in accessing the global memory address space (across many compute nodes).
- LRZ invited two experts from Fraunhofer Institute for Industrial Mathematics ITWM as teachers.
- The workshop will cover both lectures and hands-on sessions.
As scalable and flexible computing on massively parallel HPC systems based on distributed memory architectures becomes more important, we are happy to host the course on
"Introduction to GASPI - Scalability in HPC"
in cooperation with the Fraunhofer Institute for Industrial Mathematics (ITWM).
The course will take place on
Tuesday, May 8 and Wednesday, May 9, 2018, 9:00 - 16:30
at the Leibniz Supercomputing Centre of the Bavarian Academy of Sciences and Humanities at Garching b. München, Germany.
Overview
GASPI (Global Address Space Programming Interface) offers a small, yet powerful API for scalable
HPC applications following a single program multiple data (SPMD) approach. Single-sided communication primitives are supplemented
by a light weight synchronization mechanism (notifications).
Agenda
The course aims to provide an introduction to the GASPI API as well as to discuss typical use cases.
On the Linux cluster CoolMUC-2 the attendees will have the chance to apply the acquired skills.Teachers
Daniel Grünewald, Martin Kühn (Fraunhofer Institute for Industrial Mathematics ITWM, Kaiserslautern)

NEW PRACE Workshop: HPC code optimisation workshop
In the ever-growing complexity of computer architectures, code optimization has become the main route to keep pace with hardware advancements and effectively make use of current and upcoming High Performance Computing systems.
Have you ever asked yourself:
- Where does the performance of my application lay?
- What is the maximum speed-up achievable on the architecture I am using?
- Is my implementation matching the HPC objectives?
In this workshop, two leading experts, from Intel and our Intel Parallel Computing Center team at LRZ, will answer these questions and provide a unique opportunity to learn techniques, methods and solutions on how to improve code, how to enable new hardware features and how to use the roofline model to visualize the potential benefits of an optimization process.
Date: Thursday, 21 June - Friday, 22 June 2018, 9:00-17:00
Lecturers: Dr. Fabio Baruffa (Intel), Dr. Luigi Iapichino (Intel Parallel Computing Centre @ LRZ)
Further Details and Registration:
https://events.prace-ri.eu/event/727/
Registration deadline: 7 June 2018
Abstract: In this workshop we provide the opportunity to learn techniques, methods and solutions on how to improve code, how to enable the new hardware features and how to use the roofline model to visualize the potential benefits of an optimization process.
We will begin with a description of the latest micro-processor architectures and how the developers can efficiently use modern HPC hardware, in particular the vector units via SIMD programming and AVX-512 optimization and the memory hierarchy.
The attendees are then conducted along the optimization process by means of hands-on exercises and learn how to enable vectorization using simple pragmas and more effective techniques, like changing data layout and alignment.
The work is guided by the hints from the Intel compiler reports, and using Intel Advisor.
We provide also an N-body code, to support the described optimization solutions with practical hands-on.
A special focus will be dedicated to scalar and vector optimizations for the latest Intel Xeon Scalable processor, code-named Skylake, which is going to be utilized in the upcoming SuperMUC-NG machine at LRZ.
We will provide to the attendees access to Skylake processors and Intel tools using VM instances provided by Google Cloud Platform.
Please also pass this workshop announcement to other interested colleagues.
