CUDA kernel

A CUDA kernel is a function designed to be executed in parallel by multiple threads on an NVIDIA GPU following the SIMT (Single Instruction, Multiple Threads) execution model.

Core Mechanics

• Thread Hierarchy: Execution is structured into Threads, Warps, Blocks, and grids.
• Memory Management: Optimization relies on efficient access patterns across Global Memory, Shared Memory, and Registers to mitigate the Memory Wall.
• Parallelism: Leverages massive hardware scaling to perform simultaneous computations across thousands of cores.
