User-installable modules (and EasyConfigs)

Install with the EasyBuild-user module:

Technical documentation

General information

QuEST has a CMake-based installation process. It is in fact not meant for central installation. Instead, users should just download QuEST, put their application in the examples subdirectory and then use cmake with the right options to initiate the build process.

The CMake configuration file for the main library is very buggy (at least in version 3.3.0, the one that we checked). It hard-codes compiler options that overwrite any option a user may specify which is rarely a good idea. As QuEST was never meant to be installed separately, the CMake configuration file also doesn't contain the necessary logic to do a proper install of the software.

The EasyConfig setup in this directory provides its own CMakeLists.txt file that is meant to overwrite the one in QuEST/CMakeLists.txt. It installs the library part and also copies some example programs etc to the install directory only as a reference.

Note that QuEST can be build in many different configurations. Users should adapt their configuration using configopts before installing the package! The configuration parameters combined can specify 24 different configurations of which 14 are valid and produce a library (in version 3.3.0).

QuEST GPU acceleration is based on CUDA and hence is not suited for the LUMI GPU partition.

EasyBuild

  • There is no support for QuEST in the easybuilders repository (as of September 2021)

  • There is no support for Quest in the CSCS repository (as of September 2021).

Version 3.3.0 tested with cpeGNU 21.08

  • Rather than using a patch, we inject the new CMakeLists.txt file for the QuEST subdirectory via the sources. This makes it much easier to edit the CMakeLists.txt file and to further refine it.

  • We only build the code in the QuEST subdirectory using the CMAKE - make - make install buildprocess. Other files are copied manually using postinstallcmds.

  • As a centrally installed library has to be used in a different way then the manual explains, we provide some information in the module file.

Version 3.3.0 for cpeGNU 22.06, 22.08

  • Not updated yet as it is not clear if this is being used and as the previous fixes need to be modified as the CMake build process has changed.

Version 3.7.0 for cpeGNU 23.09

  • Patch step for the CMakeLists.txt is now done as a preconfig step.

  • The CPU variant hybrid-prec2 is a simple version bump from 3.3.0 to 3.7.0

  • QuEST now supports HIP therefore a new GPU variant is provided (prec2-rocm)

Archived EasyConfigs

The EasyConfigs below are additonal easyconfigs that are not directly available on the system for installation. Users are advised to use the newer ones and these archived ones are unsupported. They are still provided as a source of information should you need this, e.g., to understand the configuration that was used for earlier work on the system.
