===Upgrading the nVidia Drivers===
In MATLAB, I ran:
gpuDevice
Error using gpuDevice (line 26)
Graphics driver is out of date. Download and install the latest graphics driver for your GPU from NVIDIA.
Some quick checks showed that I was using driver version 430.26 on ubuntu 18.04.02.
nvidia-smi
lsb_release -a
I couldn't quite get MATLAB to tell me what I needed:
* https://www.mathworks.com/help/parallel-computing/gpu-computing-requirements.html
* https://www.mathworks.com/help/parallel-computing/run-mex-functions-containing-cuda-code.html#mw_20acaa78-994d-4695-ab4b-bca1cfc3dbac
For MEX, I have 10.2 and need 12.2 of the CUDA toolkit:
MATLAB Release CUDA Toolkit Version
R2024a 12.2
...
R2020b 10.2
However:
* nVidia said the latest version was https://www.nvidia.com/Download/driverResults.aspx/230357/en-us/
* The repo said the highest version for 18.04 is 545: https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa
