FlashLib: Bringing Flash Magic to Classical Machine Learning Operators
FlashLib is a new GPU library designed for classical machine learning operators, optimized for modern hardware and workloads. It demonstrates significant performance improvements over existing solutions, achieving up to 208 times faster execution for certain algorithms. The library aims to enhance the efficiency of AI systems by integrating classical ML operators into real-time processing workflows.
- ▪FlashLib offers substantial speed improvements over cuML on Hopper GPUs, with KMeans running up to 26 times faster.
- ▪The library features a predictive API that estimates runtime and memory usage for workloads in approximately 5 microseconds.
- ▪FlashLib supports multi-GPU execution and employs heuristic kernel selection to minimize autotuning delays.
