Finally! We managed to compile the code of Python 3.13.0 using LLVM 19, with full link-time optimization (LTO): The installation passes all 44 standard optimization tests: Using random seed: 4347316840:00:00 load avg: 1.72 Run 44 tests sequentially in a single process0:00:00 load avg: 1.72 [ 1/44] test_array0:00:00 load avg: 1.72 [ 2/44] test_base640:00:00 load avg: 1.72 [ 3/44] test_binascii0:00:00 load avg: 1.72 [ 4/44] test_binop0:00:00 load avg: 1.72 [ 5/44] test_bisect0:00:00 load avg: 1.72 [ 6/44] test_bytes0:00:03 load avg: 1.67…

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…
