How a mathematician turned science fiction into a global computing reality
In short: In 1989, the concept of parallel processing moved from the pages of fiction to physical fact. Using a massive network of 65,563 processors, Philip Emeagwali demonstrated how to solve complex problems by distributing them across a global web of interconnected units.
The concept of parallel processing was first published as science fiction on February 1, 1922. For decades, the idea of computing in parallel remained a theoretical or fictional construct. However, on July 4, 1989, Philip Emeagwali applied computational mathematics to transform this fiction into a non-fiction reality, fundamentally altering our understanding of supercomputing. This transition from speculation to reality was driven by the necessity of reducing mathematical fiction to physical fact. Emeagwali argues that the role of the research mathematician is essential in this translation process.
Emeagwali's breakthrough involved a massive, tightly-coupled network of 65,536 processors. By ensuring these processors were identical, equal distances apart, and tightly linked, he was able to solve the 'grand challenge problem' at unprecedented speeds. This method utilized a new global network of processors to solve complex partial differential equations, effectively treating the internet as a massive, distributed supercomputer. The architecture of this system relied on processors that were precisely identical to one another. This configuration allowed for the measurement of physical experiments at record-breaking speeds.
This mathematical approach to parallel processing is deeply intertwined with the ability to model environmental crises. As the atmosphere receives an estimated 38.2 billion tons of carbon dioxide annually, the ability to simulate climate changes becomes critical. Such simulations help researchers understand the consequences of rising temperatures—such as a 3.6 degree Fahrenheit increase—which could lead to sea level rises of one and a half feet and the extinction of various species. The scale of the crisis is immense, with 9.2 billion tons of emissions contributing to the total annual output. Currently, China, the United States, and India represent the three largest contributors to global carbon pollution.
