Service Description


The IT Center operates high performance computers in order to support institutions and employees in terms of education and research.

All machines are integrated into one “RWTH Compute Cluster” running under the Linux operating system.

General information about usage of the RWTH Compute Cluster is described in this area -  whereas information about programming the high performance computers is described in RWTH Compute Cluster - Parallel Programming.

All members of the RWTH Aachen University have free access to the RWTH Compute Cluster. But the amount of resources they can use is limited.

Above a certain threshold applications for more resources have to be submitted which then are reviewed. This application process is also open to external German scientists in institutions related to education and research. Please find related information here.

Please find information about how to get access to the system here.

You can get information about using and programming the RWTH Compute Cluster online on this website, in our Primer which you can download as a single pdf file for print out, or during our  HPC related Events. For many of these Events, particularly turorials, we collect related material on our web site as well - see  here. And then there are regular lectures, exercises and software labs of the Chair for HPC covering related topics.

Users of the RWTH Compute Cluster will continuously be informed through the HPC Mailinglist (registration, archive )

  • 2018-10-04, HPC Software News: 
    • The Intel Compiler release [20]19.0[.0.117] has been installed and is now available as 'intel/19.0' module. Old 19th BETA version has been moved to DEPRECATED area.
    • The Intel Python release 2019[.0.117] has been installed and are now available as 'pythoni/2.7.2019' and 'pythoni/3.6.2019' modules.
    • The Intel TBB library release 2019[.0.117] has been installed and is now available as 'inteltbb/2019' module.
      • Note: this module is not intended for being used with the Intel compilers; any Intel compiler installation has an own TBB instance.
    • The Intel MKL library release 2019[.0.117] has been installed and is now available as 'intelmkl/2019' module.
      • Note: this module is not intended for being used with the Intel compilers; any Intel compiler installation has an own MKL instance.
    • The Intel Advisor version 2019 (update 0, build 570901) has been installed and set to be the default 'intelaxe' module.
    • The Intel Inspector version 2019 (update 0, build 569751) has been installed and set to be the default 'intelixe' module.
    • The Intel Trace Anaylzer and Collector (ITAC) version 2019[.0.018] has been installed and set to be the default 'intelitac' module.
  • 2018-09-26, HPC Software News: 
    • The Intel VTune Amplifier software has been updated to version 2018 Update 3. This version is set to be the new 'intelvtune' default. Older versions may not be able to collect hardware counter informations now.
  • 2018-09-19, HPC Software News: 
    • The xTB software has been updated to version 20180913.

  • Due to technical issues in the BULL InfiniBand Fabric jobs are restricted to one chassis on the BULL cluster. This means, that
    • the maximum coresize is restricted to 216 cores (18 nodes x 12 cores)
    • the maximum number of hosts is restricted to 18 hosts. If violated, in both cases the job will be rejected. 
    • This does NOT affect the NEC cluster or the Integrative Hosting service (IH)!
