name: BLAS tests (Linux)
# This file is meant for testing different BLAS/LAPACK flavors and build
# options on Linux. All other yml files for Linux will only test without BLAS
# (mostly because that's easier and faster to build) or with the same 64-bit
# OpenBLAS build that is used in the wheel jobs.
#
# Jobs and their purpose:
#
# - openblas32_stable_nightly:
# Uses the 32-bit OpenBLAS builds, both the latest stable release
# and a nightly build.
# - openblas_no_pkgconfig_fedora:
# Test OpenBLAS on Fedora. Fedora doesn't ship .pc files for OpenBLAS,
# hence this exercises the "system dependency" detection method.
# - flexiblas_fedora:
# Tests FlexiBLAS (the default on Fedora for its own packages), via
# pkg-config. FlexiBLAS allows runtime switching of BLAS/LAPACK
# libraries, which is a useful capability (not tested in this job).
# - openblas_cmake:
# Tests whether OpenBLAS LP64 is detected correctly when only CMake
# and not pkg-config is installed.
# - netlib-debian:
# Installs libblas/liblapack, which in Debian contains libcblas within
# libblas.
# - netlib-split:
# Installs vanilla Netlib blas/lapack with separate libcblas, which is
# the last option tried in auto-detection.
# - mkl:
# Tests MKL installed from PyPI (because easiest/fastest, if broken) in
# 3 ways: both LP64 and ILP64 via pkg-config, and then using the
# Single Dynamic Library (SDL, or `libmkl_rt`).
# - blis:
# Simple test for LP64 via pkg-config
# - atlas:
# Simple test for LP64 via pkg-config
