The table contains performance timings for the computational task on the given machine with varying numbers of CPU cores (ncpus). The timings are presented in seconds (cputime) and are broken down into different components:
- non-local: Timings for non-local operations.
- ffm: Timings for ffm operations.
- fmf: Timings for fmf operations.
- fft: Timings for FFT (Fast Fourier Transform) operations.
- diagonalize: Timings for diagonalize operations.
"In the nvidia binary, FFT operations are exclusively performed using gpu, while BLAS3 operations are executed on the GPU. Additionally, it's important to note that the GPUs become overloaded after reaching a threshold of ncpus=6."
