tl.dot does in Triton: block-level matrix multiply using tensor cores

tensor cores do 4x4 matrix multiply in one clock cycle

Tensor cores perform 4x4 matrix multiply using optimized GEMM (General Matrix Multiply) instructions in one clock cycle

tl.load and tl.store do in Triton: read/write tensors from/to GPU global memory

`tl.load` reads tensors from GPU memory; `tl.store` writes tensors to GPU memory

to write a vector addition kernel in Triton: load blocks, add, store

```

tensor cores are

Why can computers crunch numbers faster than humans?

Triton differs from CUDA

Why does a super-fast computer sometimes run slower than a regular one?

a Triton @triton.jit decorator does: compiles a Python function into a GPU kernel
