Claims that operating on compressed arrays yields real speed and memory wins: a 22 GB Central‑Europe precipitation dataset on an 8‑vCPU VM shows about 2× runtime improvement versus an uncompressed NumPy pipeline. The stack uses Caterva multi‑dimensional chunked containers, compression via Blosc2, and expression compilation with LLVM in IronArray, tunes chunk sizes to fit L3 cache, and produces compressed outputs with multi‑threaded decompression so the approach actually works at scale.
