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. + +C-Blosc2 is the new major version of C-Blosc, and is backward compatible with +both the C-Blosc1 API and its in-memory format. However, the reverse thing is +generally not true for the format; buffers generated with C-Blosc2 are not +format-compatible with C-Blosc1 (i.e. forward compatibility is not +supported).") + (license license:bsd-3))) + (define-public ecm (package (name "ecm") |
