Matrix Multiplication Mastery: Reaching 93% of NVIDIA's cuBLAS Speed

#NVIDIA's impressive $3 trillion valuation owes much to its mastery of matrix multiplication, a critical tool at the core of machine learning development.

Here’s a peek at how to get up to 93% of NVIDIA's cuBLAS library performance:
1. Basic Matrix Multiplication: Starts our journey with basic operations, yielding 309 GFLOPs/s.
2. Memory Optimization: Advances through techniques like memory coalescing to enhance performance to 1986 GFLOPs/s.
3. Efficiency Scaling: Utilizes block and warp tiling to push limits up to 21779 GFLOPs/s, representing 93.7% of cuBLAS’s capabilities.

Arjun Jain says that he remembers, back in 2008, in the very early days of CUDA, you couldn’t even write a printf inside a kernel and had to transfer memory back to the CPU just to debug and print it—we’ve definitely come a long way!
