libopenblas64-0 0.3.8+ds-1 (arm64 binary) in ubuntu groovy

 OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13 BSD version.
 .
 Unlike Atlas, OpenBLAS provides a multiple architecture library.
 .
 All kernel will be included in the library and dynamically switched to the
 best architecture at run time (only on amd64, arm64, i386 and ppc64el).
 .
 For more information on how to rebuild locally OpenBLAS, see the section:
 "Building Optimized OpenBLAS Packages on your ARCH" in README.Debian
 .
 This metapackage provides a 64-bit indexing version.
