Summary: High performance compressor optimized for binary data
Name: blosc
Version: 1.21.2
Release: 3%{?dist}
License: MIT
Source0: https://github.com/Blosc/c-blosc/archive/v%{version}/blosc-%{version}.tar.gz

BuildRequires: snappy-devel zlib-devel libzstd-devel
BuildRequires: gcc gcc-c++ cmake lz4-devel

%description
Blosc is a compression library designed to transmit data to the processor
cache faster than the traditional non-compressed memory fetch.
Compression ratios are not very high, but the decompression is very fast.
Blosc is meant not only to reduce the size of large datasets on-disk or
in-memory, but also to accelerate memory-bound computations.

%package devel
Summary: Header files and libraries for Blosc development
Requires: %{name} = %{version}-%{release}

%description devel
The blosc-devel package contains the header files and libraries needed
to develop programs that use the blosc meta-compressor.

%package bench
Summary: Benchmark for the Blosc compressor
Requires: %{name} = %{version}-%{release}
Requires: python3-matplotlib

%description bench
The blosc-bench package contains a benchmark suite which evaluates
the performance of Blosc, and compares it with memcpy.
