High Performance Computing 25 SP Programming CUDA

Compute Unified Device Architecture

CUDA

General purpose programming model:

• Use kicks off batches of threads on the GPU.

The compiling C with CUDA applications:

CUDA APIs

Areas:

• Device management
• Context management
• Memory management
• Code module management
• Execution control
• Texture reference management
• Interoperability with OpenGL and Direct3D

Two APIs:

• A low-level API called the CUDA driver API.
• A higher-level API called the C runtime for CUDA that is implemented on top of the CUDA driver API.
