CUDA is a parallel computing platform and programming model developed by NVIDIA for general computing on graphical processing units (GPUs). It allows software developers and researchers to use the power of GPUs for accelerating computation of complex mathematical operations.
In simpler terms, imagine you have a really difficult maths problem that would take hours or even days to solve on a regular computer. With CUDA, you can use special computer parts called GPUs to solve the problem much faster. This can be incredibly helpful for scientists and engineers who need to solve complex problems quickly.
First thing to check is CUDA is already install with you hardware or not:
nvcc --version
<aside> 💡 The output will be similar to this: (depending on the cuda version installed on your system)
</aside>
<aside> 💡 if you didn’t see similar output, then check the directory.
</aside>
cd usr/local/
ls
For CUDA there will a cuda directory. There can be more than one cuda directory based on the number of versions of cuda you installed.
If you found no CUDA install then follow these steps:
sudo apt show nvidia-jetpack -a
<aside> 💡 The output would be similar to this: (not necessary be the same, just for an idea)
