| # Bit-exact CI: every push/PR must pass all 792 IEEE-754 tests. | ||
| # | ||
| # Requirements driving the setup: | ||
| # - numpy must be pip-installed (its bundled OpenBLAS exposes sdot_64_ / | ||
| # cblas_sgemm64_ / __svml_exp8 etc. that numpycpp resolves via dlsym) | ||
| # - AVX-512 hardware is required at runtime (-mavx512f compile flag + | ||
| # __attribute__((target)) guards; GitHub ubuntu-latest uses Intel Xeon | ||
| # which supports AVX-512) | ||
| # - pybind11, Eigen3, OpenMP needed to build the test extension module | ||
