%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}%{?_isa} = %{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.
