cuda-examples

A repository of examples coded in CUDA C++ All examples were compiled using NVCC version 10.1 on Linux v 5.4

Setup on Linux

1. Install Nvidia drivers for the installed Nvidia GPU. On Ubuntu-based distributions this can be done from the Software & Updates application in the tab listed as "Additional Drivers" (make sure to install the recommended version of Nvidia drivers)

2. After installing and restarting, verify that the drivers were installed by running

nvidia-smi

in a terminal window. The output should list the name of the installed card, along with some usage statistics

3. Install the nvcc compiler using the package manager

sudo apt install nvidia-cuda-toolkit

4. Verify the installation using

nvcc -V

or

nvcc --version

vecadd

CUDA implementation of vector-vector addition, adding vectors of length N, using:

• One thread per block, N blocks
• N threads in one block, grid contains only one block
• M threads in block, N/M blocks

matadd

CUDA implementation of matrix-matrix addition, adding matrices of size M x N, using:

• One thread per block, 2D grid of MxN blocks
• MxN threads in one block, grid contains only one block

matmul

CUDA implementation of matrix-matrix multiplication, with matrices of size MxN and PxQ (where N = P) Implementation using:

• 2D grid of size MxQ blocks, with 1 thread in each block
• 2D grid of size MxQ blocks, with N threads in each block and shared memory (block level)
