HPC Tuning Workshop
Mon, Dec 3 – Wed, Dec 5, 2018
IT Center
RWTH Aachen University
sponsored by:

Introduction
aiXcelerate HPC Tuning Workshop had the focus on the Intel Skylake (SKK) Microarchitecture, SIMD programming and performance tuning using Likwid, Intel VTune/Amplifier and Intel Advisor.
The nodes of CLAIX-2018, the latest RWTH Aachen University’s Supercomputer, were equipped with Intel Skylake processors and connected through a network with the Intel OmniPath architecture (OPA). It was a major extension of CLAIX-2016 system equipped with Intel Broadwell processors and connected through OPA, too.
Researchers from FZ Jülich and RWTH with high demand for compute power can apply for resources on these systems as part of the JARA-HPC partition (>>> more… ).
Researchers from all over Germany can apply for resources on Claix (>>> more… ).
The workshop consisted of presentations open to a broader auditorium and of a hands-on tuning workshop for a limited number of selected computing projects.
Presentations was given in English.
We awere proud to announce Michael Klemm and Christopher Dahnken, two HPC performance experts from Intel, who gave presentations and support your tuning efforts. Furthermore, a presentation on detecting performance limiting factors with hardware monitoring using likwid was given by Thomas Gruber (born Röhl) main developer of the Likwid tool. Experts of the HPC Team of the IT Center at RWTH Aachen University assisted in your tuning activietes as well.

aiXcelerate 2018 – Presentations

Dec 3, 11:00-13:00 – On Mon morning, Dec 3, we started at 11:00 with presentations on the new CLAIX-2018 cluster and the Skylake processor microarchitecture
Dec 3, 14:00-15:00 – After lunch on Monday, we continued with presentations on SIMD programming and performance optimization.
Dec 4, 11:00-13:00 – On Tuesday morning, Dec 4, we started at 11:00 with presentations on Likwid, Intel VTune/Amplifier and Advisor.

aiXcelerate 2018 – Tuning Workshop
After the presentations on Mon Dec 3, on Tue Dec4, and also throughout Wed, Dec 5, we provided you with hands-on opportunity to adapt, analyze and tune your performance critical applications on CLAIX, with its Skylake (and Broadwell) processors connected with the Intel OmniPath (OPA) fabric.
Participation in the presentations was a prerequisite for participation in tuning workshop.
Attendees were kindly requested to prepare and bring in their own code. It was assumed that you had a good working knowledge with MPI and/or OpenMP, and C/C++ or Fortran, whatever your compute project employs. To maximize the efficiency of the workshop, we asked the participants to prepare one or more test cases that reflected typical production runs, but did not take too long to execute – in the ideal case, a run didnot take more than 5 to 10 minutes to finish. Members of the local HPC team supported every accepted project in porting the code to Claix. By the start of the workshop the code was asked be ready to be analyzed.
Furthermore, each participant (or participating group) was kindly asked to shortly present their project (1-2 slides) at the beginning of the tuning workshop and also shortly present the outcome of the tuning efforts at the end of the workshop.
Participants who were intested in the tuning activities contacted us by sending an email to hpcevent@itc.rwth-aachen.de.
Workshop participants were invited to take part in the social dinner on Tuesday, Dec 4 in the restaurant Palladion.

Costs

Attendance was free of charge and supported by our sponsors.
Travel and accommodation were at participants own expense.

Introduction to High-Performance Computing (HPC)
This introduction provides basic information about high-performance computing (HPC) at the RWTH Aachen University’s IT Center for different target groups and needs.
It is the basis for the follow-up event PPCES.
It is focussed on the new Cluster CLAIX-2018 that only recently has been installed at the RWTH Aachen University’s IT Center in addition to CLAIX-2016, which has been installed late 2016.
Both are replacing the outdated BULL Cluster which has been installed in 2011 and which will be decommissioned until April 2019.
The event is split into two parts:
The first part provides basic information about HPC resources and targets not only HPC users but also decision markers.
It provides information for the participants to take strategic decisions concerning employment of HPC resources and filing applications for computing projects consuming a decent amount of resources.
We expect no prior knowledge of the participants.
The second part is aimed at those who (want to) use HPC resources and those who (want to) program HPC resources (developers).
It will enable participants to get a better understanding of the skill set they need.
Furthermore, it will enable admins and supporters to improve their support of HPC users by having a better understanding of HPC activities.
You will particularly learn about the most important details on using the new Cluster CLAIX-2018 that has just been installed.
Those who use to run their computing applications on local machines will learn how to run those applications on the RWTH Compute Cluster – provided the necessary software licencies are in place.
Generally, this event is also meant to teach the HPC basics that are needed to take part in our more in-depth event “PPCES” and to help take decisions on which part of PPCES might be interesting for you.
We expect participants to have a basic knowledge of Linux and experience with their applications on any other computing devices.
The presentations will be given in English.

About PPCES
This event continues the tradition of previous annual week-long events that take place in Aachen every spring since 2001.
Throughout the week we will cover parallel programming using OpenMP and MPI in Fortran and C/C++ and performance tuning. Furthermore, we will introduce the participants to GPGPU programming with OpenACC. Hands-on exercises for each topic will be provided, which should not discourage you from working on your own code.
The contents of the courses are generally applicable but will be specialized towards CLAIX the compute cluster which recently has been installed at the RWTH’s IT Center.
CLAIX is replacing the outdated BULL Cluster which has been installed in 2011 and will be decommissioned until April 2019 at latest.
The topics will be presented in a modular way, so that you could pick specific ones and register for the particular days only in order to let you invest your time as efficiently as possible. Each major topic is split into two parts: part I with basic information and part II with more advanced information. Part II always relies on contents of Part I.
Please register separately for each part under the individual parts below!
OpenMP is a widely used approach for programming shared memory architectures, supported by most compilers nowadays. We will cover the basics of the programming paradigm as well as some advanced topics such as programming NUMA machines. We will also cover a selection of performance and verification tools for OpenMP. The nodes of the RWTH Compute Cluster contain an increasing number of cores and thus we consider shared memory programming a vital alternative for applications that cannot be easily parallelized with MPI. We also expect a growing number of application codes to combine MPI and OpenMP for clusters of nodes with a growing number of cores.
The Message Passing Interface (MPI) is the de-facto standard for programming large HPC systems. We will introduce the basic concepts and give an overview of some advanced features. Also covered is hybrid parallelization, i.e. the combination of MPI and shared memory programming, which is gaining popularity as the number of cores per cluster node grows. Furthermore, we will introduce a selection of performance and correctness-checking tools.
OpenACC is a directive-based programming model for accelerators, which enables delegating the responsibility for low-level (e.g. CUDA or OpenCL) programming tasks to the compiler. Using the OpenACC industry standard, the programmer can offload compute-intensive loops to an attached accelerator with little effort. In this course, we will focus on using OpenACC on NVIDIA GPUs.
Prerequisites
Attendees should be comfortable with C/C++ or Fortran programming in a Linux environment and interested in learning more about the technical details of application tuning and parallelization.
Basic information about parallel computing architectures and about using the modules environment and the Slurm batch scheduler will be presented in the Introduction to HPC on Feb 25, 2019. Please check out the slides after this introduction if you need a quick start.
The presentations will be given in English.
Agenda

Registration
The first two days will focus on performance programming of single compute nodes mainly using OpenMP. All courses will be accompanied by practical exercises.

Shared Memory Programming – Part I: Basic OpenMP Programming – Monday, March 11, 9:00 – 17:30This course provides an introduction into parallel programming with OpenMP. It covers in detail the concepts of parallel region, worksharing, tasking, and synchronization. It also emphasizes how to write correct parallel programs. The lectures are support by many examples and hands-on exercises.
Prerequisites: nothing specific

Please register here >>>

Shared Memory Programming – Part II : Advanced OpenMP Topics – Tuesday, March 12, 9:00 – 17:30This course put the focus on improving performance of OpenMP parallel programs. It covers the interaction of OpenMP programs with the hardware and possible issues, like false sharing and remote memory accesses on NUMA architectures and vectorization for SIMD microarchitectures. It also presents recipies and case studies to improve the scalability and performance of OpenMP programs.Prerequisites (if not attending Basic OpenMP Programming): experiences with parallel programming in OpenMP, overview about the most commonly used OpenMP constructs and clauses

Please register here >>>

Days 3 and 4 will focus on performance programming of multiple compute nodes using Message Passing with MPI

Message Passing – Part I: Basic MPI Programming – Wednesday, March 13, 9:00 – 17:30
It only takes few concepts of MPI to get the first parallel programs up and running: communicators and point-to-point versus collective communication. Pratical exercises are important to get started with MPI and the first steps in using performance analysis tools help to get a better understanding of the work distribution of MPI programs in execution.
Furthermore you will learn how to debug MPI programs and how to submit MPI jobs on CLAIX using the Slurm batch system.

Please register here >>>

Message Passing – Part II: Further MPI Concepts – Thursday, March 14, 9:00 – 17:30
Actually the MPI interface provides a large number of calls, many of them you will probalby never need. But some of the concepts may be important for your application. Therefore it is important to get a rough overview of what is available and dive into some of the details at an intermediate knowledge level. The topology of MPI applications and there mapping onto a given cluster may be important for performance reasons. So you need to know how to distribute and place your MPI processes across the nodes and sockets and cores of the available compute nodes and how to specify this with respect to the Slurm batch system. In order to run your large MPI applications you need to know how to organise your parallel IO. With a growing number of cores per compute node, hybrid parallelization – a combination of MPI and OpenMP – is gaining importance. Things are not getting easier when combining both parallelization approaches: MPI and OpenMP (or MPI and multi-threading in general). How to deal with it when running (submitting using Slurm), debugging and analysing your parallel application?

Please register here >>>

The last day will focus on accelerator programming, particularly on programming NVIDIA GPGPUs.

GPGPU Programming – Part I: Basic GPGPU Programming Principles with OpenACC – Friday, March 15, 9:00 – 12:30
The number of GPU-based systems is increasing in the HPC community. However, GPGPU-based hardware architectures differ in design and programming to traditional CPU-based systems. Thus, understanding the basic GPGPU principles is essential to get good performance on such hardware architectures. In this session, we give an overview on the GPU architecture and its differences to CPUs. We introduce the basic concepts for leveraging GPUs, i.e., offloading, creating parallelism and memory management.
OpenACC is a directive-based programming model that can be used to parallelize scientific applications for GPUs. Step by step, we will introduce how to apply the basic GPU concepts with OpenACC to GPUs. This includes offloading, managed memory and data transfers. We will run through prepared examples and evaluate performance with the help of NVIDIA’s Visual Profiler.
Hands-on sessions are done on RWTH’s CLAIX Cluster with NVIDIA Pascal GPUs using PGI‘s OpenACC implementation.

GPGPU Programming – Part II: Advanced Concepts and Tuning of GPGPUs with OpenACC – Friday, March 15, 14:00 – 17:30
Understanding the mode of operations of GPUs will enable developers to achieve good performance for their GPU programs. Therefore, this session will introduce advanced concepts and tuning methods to allow GPU performance analysis and improvement. This includes the concepts of latency hiding and occupancy with hints on appropriate launch configurations and loop schedules. Furthermore, we will cover the method of asynchronous operations that also enables true heterogeneous computing on CPU and GPU. To showcase and practice these concepts, we will use the directive-based programming model OpenACC. Hands-on sessions are done on RWTH’s CLAIX Cluster with NVIDIA Pascal GPUs using PGI‘s OpenACC implementation.
Prerequisites (if not attending GPGPU Programming Part I): basic knowledge on GPU architectures (cores, streaming multiprocessors, global memory, shared memory), basic knowledge on GPU programming concepts (need for offloading, threads – blocks – grids), knowledge on basic OpenACC directives (acc kernels, acc parallel, acc loop, acc data)
Recommended (if not attending GPGPU Programming Part I): basic knowledge on using NVIDIA’s Visual Profiling, basic knowledge on how to submit batch jobs for CLAIX

HPC Tuning Workshop
Mon, Dec 2 – Thu Dec 5, 2019
IT Center
RWTH Aachen University
Kopernikusstraße 6

Content
This event focuses on CLAIX-2018, the new Supercomputer that has been set up in late 2018. In 2019, it was further extended to become the main HPC platform of RWTH Aachen University’s IT Center. It is currently the fastest computer among German universities according to the recent most TOP 500 list. (see https://www.top500.org/lists/top500/2019/06/)
CLAIX-2018
CLAIX-2018 is the main building block of CLAIX—the HPC Cluster of RWTH Aachen University—along with the previously installed CLAIX-2016. It consists of about 1300 nodes with two 24-core Intel Skylake processors and 192 GB of main memory, 54 of which are additionally equipped with two NVIDIA Volta V100 GPUs. As with CLAIX-2016, all nodes are connected via a fast Intel OmniPath network. An additional Lustre file system provides 10 PB of fast storage.
CLAIX-2018 is available to students and researchers of RWTH Aachen University. In addition, researchers from all over Germany can apply for resources on CLAIX-2018. Furthermore, researchers from FZ Jülich and RWTH with high demand for compute power can apply for resources on CLAIX-2018 (as well as on CLAIX-2016) as part of the JARA-HPC partition.
Focusing on CLAIX-2018, the aiXcelerate 2019 workshop consists of two parts:
Part I on Monday – Tuesday: Introduction to Performance Engineering and Analysis. Presentations and hands-on exercises on prepared examples are open to a broader auditorium.
Part II on Wednesday – Thursday: Hands-on tuning workshop on participants’ codes only for a limited number of selected computing projects.
We are happy to announce Michael Klemm and Mikko Byckling from Intel as well as Thomas Gruber from RRZE Erlangen as external HPC performance experts, who will support the IT Center’s HPC Team as instructors and during tuning efforts.
Presentations will be given in English.

Introduction to High-Performance Computing (HPC)
This introduction provides basic information about high-performance computing (HPC) at the RWTH Aachen University’s IT Center for different target groups and needs. It is the basis for the follow-up event PPCES. It is focused on CLAIX-2018 the cluster that has been installed end of 2018 and extended in 2019 at the RWTH Aachen University’s IT Center in addition to CLAIX-2016, which has been installed late 2016.
The event is split into two parts:
The first part provides basic information about HPC resources and targets not only HPC users but also decision makers. It provides information for the participants to take strategic decisions concerningemployment of HPC resources and filing applications for computing projects consuming a decent amount of resources. No prior knowledge is required to attend.
The second part is aimed at those who (want to) use HPC resources and those who (want to) program HPC resources (developers). It will enable participants to get a better understanding of the skill set they need. Furthermore, it will enable admins and supporters to improve their support of HPC users by having a better understanding of HPC activities. You will particularly learn about the most important details on using CLAIX-2018. Those who use to run their computing applications on local machines will learn how to run those applications on the RWTH Compute Cluster – provided the necessary software licencies are in place. Generally, this event is also meant to teach the HPC basics that are needed to take part in our more in-depth event “PPCES” and to help take decisions on which part of PPCES might be interesting for you. We expect participants to have a basic knowledge of Linux and experience with their applications on any other computing devices.

PPCES 2020
2020-12-02 - 2020-12-03 | Seminarraum 003/004, IT Center, Kopernikusstraße 6, Aachen
Online HPC Seminar and Workshop

Since we had to cancel the PPCES workshop planned for March (March, 16 – 20, 2020) this year at short notice,we are offering this online workshop on December 2nd and 3rd, 2020
Please find information about the preceeding Introduction to HPC on March 03, 2020 >>>

About PPCES

This 2-days online event will continue the tradition of previous annual week-long events that take place in Aachen every spring since 2001. This time we will only cover the basics of parallel programming using OpenMP and MPI in Fortran and C/C++ and a frist step towards performance tuning. Hands-on exercises for each topic will be included.
The contents of the courses are generally applicable but will be specialized towards CLAIX the compute cluster which is the current system installed at the RWTH’s IT Center. It might be helpful to read through the information which was provided during the HPC introduction on March 3 this year. This is especially true if you want to actively use CLAIX after this event.
OpenMP is a widely used approach for programming shared memory architectures, supported by most compilers nowadays. We will cover the basics of the programming paradigm as well as some advanced topics such as programming NUMA machines. The nodes of the RWTH Compute Cluster contain an increasing number of cores and thus we consider shared memory programming a vital alternative for applications that cannot be easily parallelized with MPI. We also expect a growing number of application codes to combine MPI and OpenMP for clusters of nodes with a growing number of cores.
The Message Passing Interface (MPI) is the de-facto standard for programming large HPC systems. We will introduce the basic concepts and give an overview of some advanced features.

Introduction to High-Performance Computing 2021
2021-03-12 11:00 - 16:30 | Online, Deutschland
This introduction provides basic information about high-performance computing (HPC) at the RWTH Aachen University’s IT Center for different target groups and needs. It is the basis for the follow-up event PPCES 2021. It is focused on CLAIX-2018 the cluster that has been installed end of 2018 and extended in 2019 at the RWTH Aachen University’s IT Center in addition to CLAIX-2016, which has been installed late 2016.
The event will be online.
The first part provides basic information about HPC resources and targets not only HPC users but also decision makers. It provides information for the participants to take strategic decisions concerningemployment of HPC resources and filing applications for computing projects consuming a decent amount of resources. No prior knowledge is required to attend.
The second part is aimed at those who (want to) use HPC resources and those who (want to) program HPC resources (developers). It will enable participants to get a better understanding of the skill set they need. Furthermore, it will enable admins and supporters to improve their support of HPC users by having a better understanding of HPC activities. You will particularly learn about the most important details on using CLAIX-2018. Those who use to run their computing applications on local machines will learn how to run those applications on the RWTH Compute Cluster – provided the necessary software licencies are in place. Generally, this event is also meant to teach the HPC basics that are needed to take part in our more in-depth event “PPCES” and to help take decisions on which part of PPCES might be interesting for you. We expect participants to have a basic knowledge of Linux and experience with their applications on any other computing devices.
All presentations will be given in English.

PPCES 2021
2021-03-22 - 2021-03-26 | IT Center, Kopernikusstraße 6, Aachen, NRW, 52074, Deutschland
About PPCES
This one week online event will continue the tradition of previous annual week-long events that take place in Aachen every spring since 2001. We will cover the basics of parallel programming using OpenMP and MPI in Fortran and C/C++ and a first step towards performance tuning as well as current topics in AI/machine learning. Hands-on exercises for each topic will be included.
The contents of the courses are generally applicable but will be specialized towards CLAIX the compute cluster which is the current system installed at the RWTH’s IT Center. It might be helpful to read through the information which was provided during the HPC introduction on March 12 this year. This is especially true if you want to actively use CLAIX after this event.
OpenMP is a widely used approach for programming shared memory architectures, supported by most compilers nowadays. We will cover the basics of the programming paradigm as well as some advanced topics such as programming NUMA machines. The nodes of the RWTH Compute Cluster contain an increasing number of cores and thus we consider shared memory programming a vital alternative for applications that cannot be easily parallelized with MPI. We also expect a growing number of application codes to combine MPI and OpenMP for clusters of nodes with a growing number of cores.
The Message Passing Interface (MPI) is the de-facto standard for programming large HPC systems. We will introduce the basic concepts and give an overview of some advanced features. Also covered is hybrid parallelization, i.e., the combination of MPI and shared memory programming, which is gaining popularity as the number of cores per cluster node grows.
Machine Learning: We provide an overview to end-to-end deep learning with the latest version of Tensorflow/Keras. It covers the basic concepts to define models with Keras and data pipelines with Tensorflow’s “Dataset”, and to visualize the results with Tensorboard while training. If training on one node or GPU is not enough, we show how to scale up/out distributed training onto multiple compute nodes and GPUs with Horovod. Furthermore, we provide an introduction to scikit-learn, with an overview of different machine learning algorithms it provides and how to utilize it on GPUs with H2O4GPU. The training courses consist of a hands-on exercises to be run directly on RWTH infrastructure.

We are very happy to present two guest speakers:

Ruud van der Pas (Oracle) on OpenMP
Georg Zitzlsberger (IT4Innovations National Supercomputing Center at VSB – Technical University of Ostrava) on Machine Learning

Prerequisites
Attendees of part I and II should be comfortable with C/C++ or Fortran programming in a Linux environment and interested in learning more about the technical details of application tuning and parallelization.
Participants of part III – machine learning – will need some basic knowledge of Python.
All presentations will be given in English.
This event will be an online presentation.
All all parts of the tutorials will be accompanied by exercises.
Participants who have access to the RWTH identity management can use their own HPC account.
Those members of RWTH who do not yet have such an account can provide an HPC account here (https://sso.rwth-aachen.de/idp/profile/SAML2/Redirect/SSO?execution=e1s1) using the selfservice (Choose: Accounts und Kennwörter – Account anlegen – Hochleistungsrechnen)
External participants must provide themselves a Linux environment that contains an OpenMP compiler, a MPI library, or respectively a singularity environment.
For parts I and II a Linux virtual machine will be sufficient.
For example on Ubuntu 20.04 LTS the following commands can be used to install the necessary software für OpenMP and MPI:
# g++ is available by default
sudo apt install gfortran # install Fortran Compiler - if necessary
sudo apt-get install libomp-dev # install OpenMP libraries
sudo apt install mpich # install MPI library
Simple program examples can be compiled and executed by
g++ -fopenmp openmp-hello-world.cc; ./a.out
gfortran -fopenmp openmp-hello-world.f90; ./a.out
mpicc mpi_hello_world.c -o ./a.out; mpirun -np 2 ./a.out
For part III (ML) participants need to run singularity containers with access to one or more NVIDIA GPUs.

Beschreibung
In diesem Jahr wurde die RWTH Aachen zusammen mit der TU Darmstadt in den Verbund für Nationales Hochleistungsrechnen (NHR-Verbund) aufgenommen. Die RWTH Aachen und die TU Darmstadt schaffen zusammen mit den anderen sechs Rechenzentren im NHR-Verbund optimale Rahmenbedingungen und bestmögliche Unterstützung für das Hochleistungsrechnen für Wissenschaftler*innen an deutschen Hochschulen. Ziel ist es, eine gemeinsame Infrastruktur aufzubauen und Hochleistungsrechnen national vernetzt voranzutreiben.
Im Rahmen von NHR4CES entstehen neue Strukturen und neue Teams, die gemeinsam, universitätsübergreifend, Forschung und Anwenderunterstützung betreiben. Eine gute Zusammenarbeit der Aachener und Darmstädter Kolleg*innen ist dabei unerlässlich, um den Erfolg des Projektes sicherzustellen.
Aus diesem Grund haben wir ein Teamevent für die Mitarbeiter*innen beider Standorte ausgerichtet, um einen bestmöglichen Start durch ein persönliches Kennenlernen zu garantieren.
Ziel dieser Teambuilding-Maßnahme war neben dem persönlichen Austausch der Wissenschaftler*innen der Aufbau eines Netzwerks der NHR4CES Mitarbeitenden und Verantwortlichen und damit ein professionelles „on-boarding“ für diese auf mindestens 5 Jahre ausgelegte Maßnahme.
Der zweite Teil der Veranstaltung, am 08.09.2021 von 08:00 – 13:00 Uhr, fand in den Räumen des IT Centers statt und umfasste einen formellen Teil, in dem die Teilnehmer*innen in kleinen Gruppen die Forschung und Arbeit ihrer Kolleg*innen näher kennenlernen.

In der Vorlesung werden Syntax und Semantik von Fortran 2008 vorgestellt, die Standardbibliothek sowie Schnittstellen zu weiteren Anwendungen.
Im Rahmen des Kurses wird Wert darauf gelegt

den aktuellen Standard Fortran 2008 zu vermitteln, aber
auch veraltete Sprachelemente vorzustellen, damit die Teilnehmerinnen und Teilnehmer in der Lage sind, Programme zu verstehen, die gemäß älteren Normen formuliert wurden,
den Teilnehmerinnen und Teilnehmern die Möglichkeiten zu verdeutlichen, die das Optimieren auf Quellcodeebene bietet.

Die Veranstaltung richtet sich an Teilnehmerinnen und Teilnehmer, die bereits eine andere Programmiersprache beherrschen. Demzufolge wird die Fähigkeit zu programmieren vorausgesetzt.
WICHTIG!
Zur Teilnahme an den praktischen Übungen benötigen Sie einen Fortran Compiler. Neben der Möglichkeit einen frei verfügbaren Fortran Compiler (z.B. ‘gfortran’ von GCC) auf Ihrem Computer zu installieren, können Sie auf die Rechner des HPC-Clusters zugreifen. Dazu benötigen Sie einen Cluster-Account sowie Zugang ins RWTH Netz (z.B. mit ‘eduroam’ oder VPN).
