Image 1 of 1: ‘A plot of Amdahl’s law with logarithmic x-axis and linear y-axis. The speed-up of a program from parallelization is limited by how much of the program can be parallelized.For example, if 95% of the program can be parallelized, the theoretical maximum speedup using parallel computing would be 20× as shown in the diagram, no matter how many processors are used. If 90% of the program can be parallelized, the theoretical maximum speed-up using parallel computing would be 10×.’
