ABINIT 9.8.2 on Discoverer HPC

27 January 2023 Veselin Kolev Comments 0 Comment

ABINIT is a powerful package for calculating a variety of optical, mechanical, vibrational, and other observable properties of materials. It is written in Fortran 95 and supports distributed parallelization model based on MPI library. This post is about how ABINIT 9.8.2 code can be compiled for high productivity on Discoverer HPC. The compilation of ABINIT code relies on the presence of a number of external auxiliary libraries, which have to be installed on the build host in advance. Most important…

5 October 2022 Veselin Kolev Comments 0 Comment

Intel® C++ Compiler Classic (icc) is deprecated and will be removed in a oneAPI release in the second half of 2023. Intel recommends that customers transition now to using the LLVM-based Intel® oneAPI DPC++/C++ Compiler (icx) for continued Windows* and Linux* support, new language support, new language features, and optimizations. https://community.intel.com/t5/Intel-oneAPI-IoT-Toolkit/DEPRECATION-NOTICE-Intel-C-Compiler-Classic/m-p/1412267 What that means for the users of Discoverer HPC who need to compile their C and C++ code by using Intel® C/C++/Fortran compiler? The classic compilers icc, icpc, ifort…

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…
