Introduction
This event will continue the tradition of previous annual week-long events that take place in Aachen every spring since 2001. Previous PPCES event was PPCES 2014.
Throughout the week, we will cover parallel programming using MPI (Monday and Tuesday) and OpenMP (Wednesday and Thursday) in Fortran and C / C++ as well as performance tuning. Furthermore, we will introduce the participants to GPGPU programming with OpenACC (Friday). Hands-on exercises for each topic will be provided, which should not discourage you from working on your own code.
The topics are 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.

Agenda

Registration Please note in your registration if you take part in Social Event – Thank you!

Mo, March 16: Message Passing with MPI – Day I Registration open here

Tu, March 17: Message Passing with MPI – Day II Registration open here

The Message Passing Interface (MPI) is the de-facto standard for programming large HPC clusters. 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 the TotalView debugger and a selection of performance and correctness tools (Score-P, Vampir, MUST).

We, March 18: Shared Memory Programming with OpenMP – Day I Registration open here

Th, March 19: Shared Memory Programming with OpenMP – Day II Registration open here

OpenMP http://openmp.org/ 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 RWTH Compute Cluster comprises a large number of big SMP machines (up to 128 cores and 2 TB of main memory) as 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.
Furthermore, we will introduce the participants to modern features of the OpenMP 4.0 standard like vectorisation and programming for accelerators and for the Many Integrated Core (MIC) Architecture.
Guest lectures and case studies complete these day’s program.

Fr, March 20: GPGPU Programming with OpenACC Registration open here

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. The open industry standard OpenACC has been introduced in November 2011 and supports accelerating regions of code in standard C, C++ and Fortran. It provides portability across operating systems, host CPUs and accelerators.
During this workshop day, we will give an overview on OpenACC while focusing on NVIDIA GPUs. We will introduce the GPU architecture. Then, we will dive into OpenACC and learn about its possibilities to accelerate code regions. We will cover topics such as offloading loops, managing data movement between host and device, tuning data movement and accesses, applying loop schedules, using multiple GPUs or interoperate with CUDA libraries. Hands-on sessions are done on the RWTH Aachen GPU (Fermi) Cluster using PGI’s OpenACC implementation.

There will be a sponsored social dinner on Wednesday, March 18 at 19:00 in Restaurant Palladion Aachen
Please register here for Part III of PPCES 2015 (Please mark if you like to attend the social dinner on Wed, March 18, 19:00)

Travel Information
Please make your own hotel reservation. You may find a list of hotels in Aachen on the web pages of Aachen Tourist Service. We recommend that you try to book a room at the “Novotel Aachen City“, ” Mercure am Graben” or “Aachen Best Western Regence” hotels. These are nice hotels with reasonable prices within walking distance (20-30 minutes, citymap.pdf) from the IT Center through the old city of Aachen. An alternative is the “IBIS Aachen Marschiertor” hotel which is close to the main station, which is convenient if you are traveling by train and also want to commute to the Center by train (4 trains per hour, 2 stops)
Please, download a sketch of the city (pdf, 415 KB) with some points of interest marked.
You may find a description of how to reach us by plane, train or car here.
Bus routes 33 and 73 connect the city (central bus station) and the stop “Mies-van-der-Rohe-Straße” 6 times per hour.
Most trains between Aachen and Düsseldorf stop at “Aachen West” station which is a 5 minutes walk away from the IT Center.
From the bus stop and the train station just walk uphill the “Seffenter Weg”. The first building on the lefthand side at the junction with “Kopernikusstraße” is the IT Center, RWTH Aachen University. The event will take place in the extension building in the “Kopernikusstraße”.
The weather in Aachen is usually unpredictable. It is always a good idea to carry an umbrella. If you’ll bring one, it might be sunny!

Introduction into Claix 2016 and Tuning Workshop
Wed, November 30 – Fri, December 2, 2016
IT Center
RWTH Aachen University
sponsored by:

Introduction
Claix2016, the first stage of Claix, short for Cluster Aix-la-Chapelle, has been integrated into the RWTH Compute Cluster by NEC and went into production in November 2016.
Therefore, we want to begin this year’s tuning workshop aiXcelerate 2016 with some introductory presentations before we then focus on tuning selected compute projects for the new machinery.
We are proud to announce HPC performance experts Michael Klemm and Christopher Dahnken from Intel and René Puttin, Daniel Tameling, and Fredrik Unger from NEC to be available for the whole workshop. They will be complemented by experts of the HPC Team of the IT Center at RWTH Aachen University.
Presentations will be given in English.

On Wed, Nov 30, 10:00 – 16:00 we are pleased to welcome experts from NEC and Intel to give an overview into the configuration and the main components of the new HPC cluster and their usage.
Agenda items will include introduction into overall configuration, Intel OmniPath network, Intel Broadwell and Intel Knights Landing processors.
Furthermore, Intel software tools for performance tuning, targeted for these new components, will be introduced and demonstrated.
This part of aiXcelerate is primarily directed towards any possible user of Claix-2016.
Please register here >>> for PART I of aiXcelerate 2016.
PART II – upon special invitation only
The main part of the aiXcelerate 2016 Tuning Workshop will focus on adaptation and performance tuning of selected compute projects upon special invitation only.
Members of approved compute projects for the JARA-HPC partition will be given priority.

Given the trend of modern Processors to contain more and more cores and wider vector units, it becomes increasingly important to optimize code for these architectures to utilize the processor in an efficient way.
In our recent tutorial(s), e.g. the PPCES 2016 event, we discussed MPI and OpenMP parallelization in detail and already some optimization techniques and tools suitable to optimize for single node performance. In this workshop, we will take a very detailed look at these topics and invite code projects to work together with experts on single node optimization and also on adaption to the new Intel OmniPath network.
This “bring-in your own code” workshop aims for you to participate with your own application code and optimize the code during the workshop with help from the HPC experts. The workshop will contain some talks presenting tools and techniques for code optimization, but most of the time is reserved for code work on the RWTH Aachen compute cluster.
As we plan to accommodate several representatives from the user community, we will have to time slice between the participants. Where needed, we will give advice and then ask you to try it, while we work with other attendees. Performance tuning is still a matter of some experimentation, but we can give you advice on a best effort basis. Hopefully this will lead to a noticeable performance improvement, but guarantees cannot be given.
The first hands-on session for porting and analyzing application codes starts on Wed, Nov 30, 16:00. During the following two days we will start at 9:00 in the morning and finish at about 17:30 in the afternoon. Thursday, Dec 01 will end with an social dinner sponsored by ho-computers.
Prerequisites and your Preparation in PART II
Attendees are kindly requested to prepare and bring in their own code. It is assumed that you have 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 would like to ask you to prepare one or more test cases that reflect typical production runs, but do not take too long to execute – in the ideal case, a run should not take more than 5 to 10 minutes to finish. Members of the local HPC team will support every accepted project in porting the code to the new machines of the RWTH Compute Cluster. By the start of the workshop the code should be ready to be analyzed.
Claix-2016 consists mainly of two node types:
(1) CLAIX2016-MPI: 600+ nodes have two Intel Xeon E5-2650v4 (Broadwell) processors (2,2 GHz, 12 cores each) with 24 cores in total and 128 GB main memory.
(2) CLAIX2016-SMP: 8 nodes comprise eight Intel Xeon E7-8860v4 (Broadwell) processors (2,2 GHz, 18 cores each) each node has 144 cores in total and 1024 GB main memory.
The machines are all integrated into the RWTH Compute Cluster which is currently operated under CentOS 7.2 Linux, so all codes need to run there.
Furthermore, we ordered some additional compute nodes equipped with 64 core Xeon Phi Knights Landing processors (KNL). But presumably those will not yet be available at the time of the tuning workshop.
Most likely only one KNL system will be available on site for the workshop.
Please, take these boundary conditions into consideration when preparing your test cases.

Registration
PART I: Please register here >>>(once registration is opended) if you want to participate in PART I of aiXcelerate 2016 on Wed, Nov 30, 10:00 – 16:00

PART II: Participation in PART II is upon special invitation only. Participation of PART I is a prerequisite of taking part in PART II.
We plan to support up to ten compute projects. Each project can be represented by up to three participants.
Please contact Paul Kapinos (hpcevent@itc.rwth-aachen.de) if you have any questions.
PARTII of the workshop will start on November 30, 16:00 and end on December 2, 2016, 17:30.
A social dinner sponsored by ho-computer will take place on Thursday, Dec 1 in the restaurant Palladion.

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 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. Please register separately for each event day.
Guest lectures by Ruud van der Pas (Oracle), Thomas Röhl (RRZE), Bernd Dammann (TUD) and case studies complete the program.

Participants
Attendees should be comfortable with C/C++ or Fortran programming and interested in learning more about the technical details of application tuning and parallelization. The presentations will be given in English.
Registration – is open!!
I. + II. 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 RWTH Compute Cluster contains a number of big SMP machines (up to 144 cores and 2 TB of main memory) as 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.
Furthermore, we will introduce the participants to modern features of the OpenMP 4 standard like vectorization and programming for accelerators and for the Many Integrated Core (MIC) architecture.

March 20 – Part I Shared Memory Programming with OpenMP Day I
March 21 – Part II Shared Memory Programming with OpenMP Day II

III. + IV. 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 the TotalView debugger and a selection of performance and correctness-checking tools (Score-P, Vampir, MUST).

March 22 – Part III Message Passing with MPI Day I
March 23 – Part IV Message Passing with MPI Day II

V. 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. We will give an overview on OpenACC while focusing on NVIDIA GPUs. We will cover topics such as the GPU architecture, offloading loops, managing data movement between hosts and devices, using managed memory, tuning data movement, hiding latencies, and writing heterogeneous applications (CPU + GPU). Finally, we will also compare OpenACC to OpenMP device constructs. Hands-on sessions are done on the RWTH Aachen GPU (Fermi) Cluster using PGI‘s OpenACC implementation.

HPC Tuning Workshop
Tue, Dec 5 – Thu, Dec 7, 2017
IT Center
RWTH Aachen University
sponsored by:

Introduction
This year’s aiXcelerate HPC Tuning Workshop will focus on two topics:

MPI+OPA: Tuning of parallel programs employing message passing with MPI and running on the Intel OmniPath fabric.
KNL: Tuning for Intel’s Xeon Phi new many core processor

The nodes of Claix, the latest RWTH Aachen University’s Supercomputer, are equipped with Intel Broadwell processors and connected through a network with the Intel OmniPath architecture (OPA). Claix has recenlty been complemented by 16 nodes containing an Intel’s Xeon Phi 7210 processor – code named Knights Landing (KNL). At the Jülich Supercomputer Centre a cluster called “Booster” will soon be installed which will contain Intel’s Xeon Phi many core 7250-F processors and an Intel OmniPath fabric. The KNL nodes at Aachen can well be used to prepare and tune programs for Booster.
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 will consist of presentations open to a broader auditorium and of a hands-on tuning workshop for a limited number of selected compute projects.
Presentations will be given in English.
We are proud to announce Michael Klemm and Christopher Dahnken, two HPC performance experts from Intel, who will give presentations and support you with your tuning efforts. They will be complemented by experts of the HPC Team of the IT Center at RWTH Aachen University.

IT Center Infotag 2018
2018-01-16 08:00 - 17:00
This entry is only available in Deutsch. Name: IT Center Infotag 2018: “Informieren, Zuhören und Diskutieren – die Zukunft gemeinsam gestalten”

Veranstaltungsart: Informationsveranstaltung
Ort: IT Center der RWTH Aachen

Zielgruppe: Interessierte

Beschreibung
Der Infotag 2018 richtete sich erstmalig in einem neuen Format ausschließlich an die Entscheidungsträger und Führungskräfte aus den Bereichen Forschung, Lehre und Verwaltung sowie an Studierendenvertreter und die Steuerungsgruppe des IT Centers.
Entsprechend dem Motto Informieren, Zuhören und Diskutieren – die Zukunft gemeinsam gestalten diskutierten die Teilnehmenden in vier Diskussionsforen und einer abschließenden Podiumsdiskussion über Zukunftsthemen und die Frage, wie Informations- und Kommunikationstechnologien sie und die Exzellenzstrategie der Hochschule unterstützen können.
Die in den vier Foren und bei der abschließenden Diskussion geäußerten Anregungen und Wünsche der Kundinnen und Kunden, sind von entscheidender Bedeutung für die kontinuierliche Weiterentwicklung und Verbesserung des IT-Angebots.

Agenda

Informieren – über die Aktivitäten des IT Centers; mit einem Impulsvortrag als Einstieg / Ideengeber für die Diskussionsforen.
Zuhören und Diskutieren – in vier parallelen Diskussionsforen zu den unten aufgelisteten Themengebieten. Alle vier Themen der Diskussionsforen ergaben sich aus den Vorschlägen der Teilnehmenden.

„IT Sicherheit – wie viel Sicherheit braucht und verträgt die RWTH wirklich?“
„Offene Innovationswerkstatt“
„Kollaborationsunterstützung und Cloud – wie sieht unsere Arbeitsweise künftig aus?“
„(Forschungs-) Datenmanagement – was hat die RWTH, was braucht die RWTH?“

Die Zukunft gemeinsam gestalten – in der abschließenden Podiumsdiskussion wurden die zuvor von den Moderierenden zusammengéfassten Schwerpunkte der Diskussionsforen aufgegriffen und im Hinblick auf ihre Rolle und Bedeutung bei der Exzellenz-Initiative und der Digitalisierungsstrategie der RWTH diskutiert.

Veranstaltungsunterlagen
Forum I: „IT Sicherheit – wie viel Sicherheit braucht und verträgt die RWTH wirklich?“
Forum II: „Offene Innovationswerkstatt“
Forum III: „Kollaborationsunterstützung und Cloud – wie sieht unsere Arbeitsweise künftig aus?“
Forum IV: „(Forschungs-) Datenmanagement – was hat die RWTH, was braucht die RWTH?“

Fazit
Die sehr positiven Rückmeldungen der Teilnehmenden haben bestätigt, dass es ein Schritt in die richtige Richtung war, bereits im Voraus in den Dialog mit den Beteiligten zu gehen. Unter den Teilnehmenden entstand sogar die Idee, das neue Infotag-Format als künftigen und regelmäßigen „IT-Tag der RWTH“ zu etablieren.
Die rege Teilnahme aller Beteiligten und das aufmerksame Zuhören ermöglichte es dem IT Center, neue wertvolle Erkenntnisse zu gewinnen und stellte eine wirkliche Bereicherung für alle dar. Alle Ideen und Anregungen, die auf den folgenden Seiten detailliert aufgeführt sind, wurden bei den Aktivitäten im Bereich der Exzellenz-Initiative und bei der Weiterentwicklung der IT-Services berücksichtigt.
Auch wenn das neue Infotag- Format für die Organisatoren im Voraus sowie im Nachgang ein Kraftakt war, so überwog am Ende die Freude über den großen Erfolg der Veranstaltung.

About PPCES
This event continued the tradition of previous annual week-long events that take place in Aachen every spring since 2001.
Throughout the week we covered parallel programming using OpenMP and MPI in Fortran and C/C++ and performance tuning. Furthermore, we introduced the participants to GPGPU programming with OpenACC. Hands-on exercises for each topic were provided, which did not discouraged the participants from working on their own code.
The topics were presented in a modular way, so that the participants could pick specific ones and register for the particular days only in order to let them invest their time as efficiently as possible.
Guest lectures by Ruud van der Pas (Oracle), Jan Eitzinger (RRZE) and Thomas Röhl (RRZE), completed the program.

Participants
Attendees should be comfortable with C/C++ or Fortran programming and interested in learning more about the technical details of application tuning and parallelization. The presentations will be given in English.
Registration – closed
I. + II. 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 (Score-P, Vampir, MUST)
III. + IV. 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 RWTH Compute Cluster contains a number of big SMP machines (up to 144 cores and 2 TB of main memory) as 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.
V. 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. We will give an overview on OpenACC while focusing on NVIDIA GPUs. We will cover topics such as the GPU architecture, offloading loops, managing data movement between hosts and devices, using managed memory, tuning data movement, hiding latencies, and writing heterogeneous applications (CPU + GPU). Finally, we will also compare OpenACC to OpenMP device constructs. Hands-on sessions are done on RWTH’s CLAIX Cluster with NVIDIA Pascal GPUs using PGI‘s OpenACC implementation.
Travel Information
Please make your own hotel reservation. You may find a list of hotels in Aachen on the web pages of Aachen Tourist Service. We recommend that you try to book a room at the Novotel Aachen City, Mercure am Graben or Aachen Best Western Regence hotels.

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.

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.

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.

Travel Information
If required, please make your own hotel reservation.You can find some popular hotels listed here. You may find a complete list of hotels on the web pages of the Aachen Tourist Service. We recommend that you try to book a room in the “Novotel Aachen City“, ” Mercure am Graben” or “Aachen Best Western Regence” hotels. These are adequate hotels with reasonable prices at a walking distance (20-30 minutes) to the IT Center through the old city of Aachen. An alternative is the hotel “IBIS Aachen Marschiertor” which is close to the main station, which is convenient if you are travelling by train and also want to commute to the IT Center by train (3 trains per hour, 2 stops)
Please, download a sketch of the city (pdf, 415 KB) with some points of interest marked.
You may find a description of how to reach us by plane, train or car here.
Bus route 33 connects the city and the stop “Mies-van-der-Rohe-Straße” every 15 minutes.
Trains between Aachen and Düsseldorf stop at “Aachen West” station which is a 5 minutes walk away from the IT Center.
From the bus stop and the train station just walk uphill the “Seffenter Weg”. The first building on the left hand side at the junction with “Kopernikusstraße” is the IT Center.

The weather in Aachen is usually unpredictable. It is always a good idea to carry an umbrella. If you’ll bring one, it might be sunny!

Technical Information for Tuning Workshop Participants
Workshop participants should have an account at the HPC Cluster in Aachen. Participants were asked not to bring in their own laptop. The IT Center provided a lend device; in this case please be equipped also with the ‘PC Pool‘ account (get it via Selfservice).
Please contact us and send us your HPC account (like ab123456) so we can add you to the project “hpclab” for the workshop.
