We’ve been examining the deployment of LLVM compiler infrastructure in high-performance computing for more than a year. LLVM compilers provide novel and significantly more optimal and reliable schemas for the generation of binary code. More and more source code distributions come with LLVM-compatible CMake configurations. GROMACS is one of them. The Python universe of applications also actively adopts LLVM for HPC. Numba is one of those applications. It serves as a foundation for the development of bindings for the creation of…

OpenBLAS is a CPU-level optimized replacement to BLAS/LAPACK. In most cases it can substitute BLAS and/or LAPACK in attempt to achieve higher productivity, which is the main goal of most HPC applications. The last release of OpenBLAS (that is 0.3.21) has some critical problem with configuring the compilation whenever USE_OPENMP=1 is passed to make, in case Intel oneAPI compilers are employed. The problem is in the Makefile. At some point there the ifort compiler becomes invoked without passing the necessary…
