- CUDA:
- CUDA =
acronym for
Compute Unified Device Architecture
CUDA is a (vector) parallel computing platform and application programming interface (API) model created by Nvidia (a graphics card company).

- The CUDA architecture:
Important fact about the CUDA architecture:
- The host system and the
GPU system
are 2 separate systems:
- RAM (= host memory) that is only accessible by the CPU
- Device memory that is only accessible by the GPU
- Data stored in RAM/Device memory must be transfered to each other through a bus by a DMA
- The host system and the
GPU system
are 2 separate systems:
- A computer program that
uses the
GPU (graphics processor)
will consist as
2 parts:
- A part (portion of computer program)
that runs (= executes)
on the host computer
- A part (portion of computer program) that runs (= executes) on the CPU processor ("GPU computer")
- A part (portion of computer program)
that runs (= executes)
on the host computer
- A CUDA program consists of
2 parts:
- A CPU part that consists of
CPU instructions
(i.e., "normal" computer instructions
stored in
the RAM memory
that is executed by
the CPU
- A GPU part that
consists of GPU (graphics processor)
instructions stored in
the (GPU) device memory
that
is executed by
the vector processing
