Reevaluating AI Supercomputer Metrics
The Limitations of FLOPs FLOPs are Not Enough: The Importance of Cache Efficiency While FLOPs provide a measure of an AI supercomputer’s processing power, they neglect to account for the crucial role of cache efficiency in determining overall performance. Caches are small, fast memories that store frequently accessed data and instructions, allowing them to be retrieved quickly without accessing slower main memory. Efficient use of caches can significantly reduce memory access latency, leading to improved processing speeds....
