Cryptographic Hash & SIMD Stress Testing
The SHA-256 module implements hardware-accelerated cryptographic hashing using Intel SHA-NI (SHA New Instructions) extensions. This module combines intensive SIMD operations, parallel state processing, and complex bit manipulations to create maximum stress on your CPU's vector processing units and cryptographic acceleration hardware.
Utilizes Intel's dedicated SHA-256 instructions for hardware-accelerated cryptographic operations. Four parallel hash states process different data streams simultaneously, maximizing throughput and SIMD unit utilization.
Advanced message scheduling using SHA256MSG1 and SHA256MSG2 instructions combined with complex data shuffling patterns. Multiple data streams are processed with byte swapping and realignment operations for maximum computational density.
Dedicated cryptographic hardware acceleration units are saturated with continuous SHA-256 round operations and message scheduling.
128-bit XMM registers and vector operations stress SSE/AVX execution pipelines with parallel data processing.
Intensive byte shuffling, bit rotation, and data alignment operations stress the CPU's shuffle and permutation units.
Multiple data streams with 64-byte aligned access patterns create sustained memory bandwidth utilization.
Automatic CPUID-based detection of SHA-NI support with graceful fallback for unsupported processors.
Four independent hash states process different data streams simultaneously for maximum throughput.
Dynamic data stream switching prevents cache optimization and maintains computational complexity.
Combination of cryptographic, integer, and floating-point operations for comprehensive CPU stress.
This module requires Intel SHA-NI support (Intel processors from Goldmont/Skylake generation onwards, or AMD Zen architecture). The module includes runtime detection and will report compatibility. Extended execution will saturate cryptographic units and may cause thermal throttling.
