SDCShield detects silent data corruption (SDC) on live systems: stress-tests CPU compute units (FMA/SIMD/compression/SVD/crypto) and byte-compares against golden values. ARM64 port of OpenDCDiag.
SDC excitation engine for arm64 servers — a stress-ng fork that spends every cycle maximizing silent-data-corruption excitation (di/dt, SMT contention, cache/TLB/interconnect pressure, SDC-directed data shaping). Detection is delegated to SDCShield.
