Coreinfo

Coreinfo provides a clear, technical summary of your computer's central hardware. It goes beyond basic specs to show the intricate relationships between physical CPUs, their caches (L1, L2, L3), and the system memory. A key feature is its reporting on Non-Uniform Memory Access (NUMA) nodes, illustrating how memory is logically grouped and associated with specific processors or sockets. This data is vital for anyone working with multi-socket systems, virtualization, or high-performance computing applications where understanding memory locality and processor affinity is critical for achieving optimal efficiency.
