I implemented Assignment 3 using the Mahti supercomputer. Using Windows, I had trouble connecting, and it took a long time to get it working. Using Mahti with VS Code was easy once I got in.
At first, I read the .raw files incorrectly a few times, which gave me strange numbers and gave me array length errors, or 0.0 as output, but I had just made some obvious mistakes that I later fixed and got the correct output.
The mahti job queue was also quite long at times, and I had to wait 30 minutes to get my results, but on Saturday, it was almost instant.
I tested the tiled CUDA matrix multiplication using a tile width of 16 and 32, and I did not notice any significant change in speed. - Other than that, no major difficulties.
