Numba is an open-source Just-In-Time (JIT) compiler designed to translate a subset of Python and NumPy into fast machine code. It utilizes the LLVM framework via the llvmlite Python package to achieve high-performance execution.
The software provides various options for parallelizing Python code across both CPUs and GPUs, often requiring only minor modifications to existing scripts. While the user prompt identifies Numba as a city in Indonesia, the provided source material defines it exclusively as a computational programming tool.
