User-installable modules (and EasyConfigs)

Install with the EasyBuild-user module:

eb <easyconfig> -r

To access module help after installation and get reminded for which stacks and partitions the module is installed, use module spider MicroHH/<version>.

EasyConfig:

• EasyConfig MicroHH-2.0.1-cpeGNU-24.03.eb, will build MicroHH/2.0.1-cpeGNU-24.03

  CPU version, compile for partitioon/C and run on LUMI-C.

Technical documentation

MicroHH is a computational fluid dynamics code designed to simulate turbulent flows in the atmosphere using Direct Numerical Simulation (DNS) and Large-Eddy Simulation (LES) techniques. Its capabilities span a range from highly idealized flows to realistic atmospheric boundary layers, incorporating all relevant processes, such as moist thermodynamics, radiation, land surface processes, and microphysics. The code is written in C++/CUDA and runs on both CPUs and GPUs (but only NVIDIA at the time of writing).

EasyBuild

Version 2.0.1 for cpeGNU

• The EasyConfig was contributed by the EPICURE project.

• When having trouble after a system update, it may be a good idea to move Boost to the regular depencencies as now many system libraries are used that may or may not be present after a system update.
