As data volumes continue to grow in fields like machine learning and scientific computing, optimizing fundamental operations like matrix multiplication becomes increasingly critical. Blosc2's chunk-based approach offers a new path to efficiency in these scenarios.

Blosc is a high performance compressor optimized for binary data (i.e. floating point numbers, integers and booleans, although it can handle string data too). It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc main goal is not just to reduce the size of large datasets on-disk or in-memory, but also to accelerate memory-bound computations.
