Philip Emeagwali's video: How I Invented the Philip Emeagwali Supercomputer Famous Computer Scientists and their Inventions

I'm @Philip Emeagwali. The supercomputer is not fast enough to simulate the long term changes in the Earth’s atmosphere, that is also known as global climate change. For the four decades onward of 1946, the sequential processing or vector processing supercomputer powered by only one isolated processor —that was not a member of an ensemble of processors—inspired the development of weather forecasts. Each weather forecast is computed from a supercomputer model that is rooted in a companion mathematical model that is rooted on the laws of physics. At the foundation of the supercomputer weather forecast is a large system of partial difference equations of algebra that was derived from finite difference discretizations and approximations of the primitive equations of meteorology. The primitive equations are a system of coupled, non-linear, time-dependent, and state-of-the-art partial differential equations that is the toughest problem in calculus. For those four decades, the weather forecast was generated within a supercomputer that used only one isolated processor that was not a member of an ensemble of processors. One of the reasons the weather forecast of today is more accurate than the weather forecast of the first four decades, onward of 1946, is that today’s weather forecast is simultaneously computed in parallel, and synchronously communicated across up to ten million tightly-coupled already-available processors that shared nothing with each other. My invention of the massively parallel processing supercomputer was independent of processor technology. That invention was a blueprint for a new internet that I envisioned as being a subset of the Internet. I visualized that new internet as being at the core of an emergent Cosmic Brain. The Modern Supercomputer I invented how to forecast the weather and how to do so with greater accuracy and how to do so across my new internet that is a global network of 65,536 tightly-coupled processors. In my invention, the weather is forecast by executing the set of floating-point arithmetical operations that arises from solving the primitive equations of meteorology. The primitive equations is a system of coupled, non-linear, time-dependent, and state-of-the-art partial differential equations of modern calculus. I discretized and replaced the primitive equations with my system of equations of extreme-scale algebra that, in turn, approximated those partial differential equations. I invented how to solve the arising system of equations of algebra that arose from the primitive equations of meteorology and calculus and how to solve that extreme-scaled algebraic problem and solve it across my new internet that is a new global network of 64 binary thousand tightly-coupled, processors. Those already-available processors were identical and were equal distances apart. That new global network of processors was a new internet. I invented that new internet to be at the granite core of the high-performance supercomputer that I used to compute in parallel. In contrast to the new massively parallel processing supercomputer, the old sequential processing or the old vector processing supercomputer computed sequentially, or solved only one problem at a time. I invented how to more accurately forecast the weather and how to forecast it across the globe and across a new global network of tightly-coupled processors that is a new internet. I programmed that new internet as a new global network of two-raised-to-power-sixteen processors. I visualized that new internet as a global network of millions upon millions and billions upon billions of identical processors that had better cost-benefit ratio. The new supercomputer that I invented is less expensive because its processors were mass produced and were already available in the market. The reason my invention of the massively parallel processing supercomputer was reported in the news media and reported in the June 20, 1990 issue of The Wall Street Journal was that it was then a technological breakthrough to harness a new internet that is a new global network of 64 binary thousand identical processors. It was a technological breakthrough to invent how an ensemble of the slowest processors in the world could be harnessed and used to compute faster than any vector processing supercomputer that computed with the fastest processor.
