Example · Parallel process

Ants working together to forage for food.

██ ██ ██ █████████████ █ ████ ██ ████ █████████ ████ ████████ ████ ███ █████

Analogy · Ants working together are like a computer

Application · Of parallel processes to computing

Involves many computers working simultaneously on different calculations.

Advantage of parallel computing · Better suited than sequential computing to solving parallel problems

Passage Style

The large-scale climate trends discussed ██ ███████ █ ███ ████ █████████ ██ █████ ███ ██ ███ █████████ ████████ ██ ███████ ██

the thousands of █████████ ███████ ██████████████ ██ █████ █ █████████████████████ ███████

This might describe the computing system that will help model or help solve complex systems, but this isn’t analogous to the complex system itself.

12%

the simple rules ████ █████ ███ ████████ ██ █ ██████ ███

The complex system would involve the mass of thousands of ants working together, not just the individual ant.

the highly complex ████████ ██ █ █████ ████ ██ █████████ ██ ████

The way ants forage for food is an “example” of a “highly complex system.”

80%

the paradigm shift ████ ██████████ ██ ████████ █████████

The paradigm shift is not itself a complex system. Paralell computing is the form of computing that might lead to solving of problems involving complex systems.

the speed limits ███████ ██ █████████ ██████ ████████████

There’s nothing about the speed limits of sequential computing that suggests a complex system involving many variables.
