Parallel Computing
A graphical representation of Amdahl's law. The speed-up of a program from parallelization is limited by how much of the program can be parallelized. For example, if 90% of the program can be parallelized, the theoretical maximum
speed-up using parallel computing would be 10x no matter how many processors are used.
