mipster 0.2.3

Pre-built MIPster MIP solver shared library (CPU-dispatched)

mipster (Python wheel)

This directory packages MIPster as a binary Python wheel. It does not rebuild the C++ sources — it repackages the platform-specific tarballs produced by the existing CI scripts under .github/scripts/.

Layout inside the wheel

On Linux aarch64 the optimised dir is mipster_dist_neon (ARMv8.2-A). On macOS x86_64 it is mipster_dist_haswell. macOS arm64 ships only the baseline (M1+ ARMv8.5-A — no dispatch needed).

Building a wheel locally

export MIPSTER_VERSION=3.0.0.dev0
export MIPSTER_PLAT_TAG=manylinux_2_34_x86_64
export MIPSTER_TARBALL=/path/to/mipster-linux-x86_64.tar.gz
python -m build --wheel

CPU dispatch at runtime

import mipster
print(mipster.selected_variant())   # 'avx2' | 'generic' | 'neon' | ...
print(mipster.lib_path())           # absolute path to libmipster.{so,dylib,dll}

Override with the MIPSTER_BUILD env var:

export MIPSTER_BUILD=generic   # force baseline
export MIPSTER_BUILD=avx2      # force AVX2 (errors out if not bundled)
