Cuda Better -

The CPU and its system memory (host memory). It manages the overall control flow of the program.

A collection of threads that execute together on a single Streaming Multiprocessor (SM). Threads within the same block can synchronize with each other and share high-speed memory. The CPU and its system memory (host memory)

Running high-frequency Monte Carlo simulations to assess portfolio risk. Threads within the same block can synchronize with

Efficient memory management is critical in CUDA programming because the bandwidth and latency of different memory types heavily dictate application performance. Memory Type Access Speed Single Thread Thread Lifetime Shared Memory Extremely Fast Thread Block Block Lifetime Global Memory Off-Chip (VRAM) All Threads + Host Application Lifetime Constant Memory Off-Chip (Cached) Fast (when cached) All Threads Application Lifetime Memory Optimization Techniques Memory Type Access Speed Single Thread Thread Lifetime

The smallest unit of execution. A thread executes a single copy of a CUDA kernel on a single data point.
