Performance Results

The following results are obtained on a machine with an AMD Ryzen 7 5700g processor and NVIDIA GeForce RTX 3060 GPU, by running the ./runBenchmarks.sh script in the root directory.

Note that some runtimes might not add up to the total time reported. This is due to the intermediate times being rounded.
