Which FFTW3 build to use on Discoverer

11 September 2022 Veselin Kolev

FFTW3 is an important library package that provides large number of HPC applications with a collection of external subroutines for computing the discrete Fourier transform (DFT) in one or more dimensions. In HPC environment it is a common case to have several different builds of FFTW3 available to support the variety of installed MPI libraries, threads libraries, and common models for application code building, linking, and executing. But in spite how many such builds are presented locally, the most compatible…

LLVM project released version 14.0.6 of their source code. Immediately after that the LLVM compiler infrastructure was compiled and installed in the Discoverer HPC software repository (made available to all HPC users). It is worth mentioning here the way the source code was compiled, since the details of that process reflect the good practice in compiling for AMD Zen2 CPU. The compile recipe is publicly available at: https://gitlab.discoverer.bg/vkolev/recipes/-/tree/main/llvm/ In the recipe, it is better to employ GCC 11 compilers than…

WRF 4.4 as service

Many governmental and non-governmental organizations, as well as a number of businesses (like wind farms), rely on precise local weather forecast. Weather Research and Forecast model (WRF) is the most popular and well developed software set of tools for generating such type of weather forcasts. It is freely distributed as a programming (source) code, large part of which is written in Fortran programming language. It is expected that the potential WRF users should download, compile, and running the WRF tools…
