Framework ports Intel x86 SIMD intrinsics to OpenPOWER ISA by running the same tests on two machines connected over the network and asserting identical results. It implements a network module in Python, a C extension for Python testing module, a shared random m256d generator to feed identical inputs, and comparison of outputs plus latency and throughput measurements. Tests run on real hardware or QEMU controlled via GDB/MI to read registers. The project is open source and aims for bit‑identical correctness.
