cpuminer-opt is an optimized fork by developer (also known as JD or tpruvot contributors). The hallmark of cpuminer-opt is its aggressive use of CPU vector extensions— AES-NI, AVX, AVX2, and even AVX-512 on modern Intel/AMD chips . flag to bind threads to specific physical cores,

It excels at scaling across high-core count processors, though users often find better efficiency by limiting threads to the number of physical cores rather than logical threads. ⚠️ Important Considerations
