QPET: A Versatile and Portable Quantity-of-Interest-Preservation Framework for Error-Bounded Lossy Compression

Summary: QPET: a portable numerical framework that enforces QoI (quantity‑of‑interest) preservation for error‑bounded lossy compressors and plugs into many existing compressors. Supports differentiable uni/multivariate QoIs and yields 2×–10× speedups and up to 10× compression‑ratio gains in experiments. (summarized by gpt-5-mini on Feb 09 2026)
