occupancy means in GPU programming

CPU cache

L1/L2 cache hierarchy reduces global memory latency

warp divergence kills performance

Warp divergence causes threads to execute non-uniformly, leading to idle cycles and reduced throughput

tensor cores are

Why can computers crunch numbers faster than humans?

CUDA

CUDA enables parallel computation on GPUs

Nvidia

Ever wondered how video games run so smoothly on your computer?

Dynamic random-access memory

DRAM requires periodic refreshing to maintain data integrity
