has many fathers and mothers as well as aunts and uncles.

We can only have one father of the Internet

that invented a new internet. The father of the Internet

should at least invent a new internet. I am called a father of the Internet because

I am the only father of the Internet that invented a new internet. I invented my new internet

by, first, theorizing it back in 1974 and then continuously developed it

for the subsequent fifteen years and developed

that small copy of the internet and did so until I actualized it

as the fastest computation back on the Fourth of July 1989.

My two-raised-to-power sixteen commodity-off-the-shelf processors

were tightly-coupled to each other and were equal distances apart

from each other. I mathematically visualized

my 64 binary thousand processors as tightly-encircling a hyper globe

that is bounded by the hypersurface

of a sixteen-dimensional hypersphere that is embedded

within a sixteen-dimensional hyperspace. I visualized

the physical and mathematical domains of my extreme-scale, high-resolution

general circulation model as the 62-mile deep

hyper-spherical shell that was bounded by two hyperspheres.

The inner hypersphere has a diameter of 7,900 miles

that corresponded to the surface of the Earth.

The outer hypersphere has a diameter of 7,962 miles

that corresponded to the outer boundary

of the atmosphere of the Earth. I visualized

the two-raised-to-power sixteen vertices of my hypercube

to be midway (or 31 miles) between those two hyperspheres.

I drew parallels between my new internet

that was a new global network of processors

and how I envisioned simulating global warming.

My two hyperspheres were parallel to each other.

My two hyperspheres extended in the same direction.

My two hyperspheres never converged or diverged.

My 65,536 processors were paralleled

with respect to the climate model that I divided into

65,536 smaller climate models. Those climate models

were identical in domain size. [Paradigm Shift in Computing] My discovery

of practical parallel supercomputing created a paradigm shift

on how we look at the computer and the internet

of tomorrow. Practical parallel supercomputing

led to my new definition of the supercomputer

as powered by millions upon millions of processors,

rather than one singular processor. Practical parallel supercomputing

was mocked, ridiculed, and rejected during the sixty-seven years

onward of its first conceptualization that occurred in print

back on February 1, 1922. After my discovery

of practical parallel supercomputing that occurred on the Fourth of July 1989,

the supercomputer industry took my invention

and made it the vital technology within every supercomputer.

But for the sixty-seven years prior to my invention,

practical parallel supercomputing remained in the realm of science-fiction.

My contribution to the development of the computer

is this: I upgraded

the parallel supercomputer from science-fiction to non-fiction.

I discovered how to maintain a one-problem to one-processor correspondence,

or analogy, between the smaller

general circulation models and the processors.

I discovered how to communicate synchronously

and how to compute simultaneously and how to communicate and compute and do

both 65,536 times faster and do both on 65,536

central processing units, and across sixteen times

as many email paths. In other words, I paradigm shifted

in my email communication across my new internet.

I discovered how to harness processors

and how to shift from the singular,

person-to-person email to the plural

processor-to-processor emails that I synchronized across

my new internet that is a new global network of

65,536 tightly-coupled central processing units. That new global network defined

a parallel supercomputer that is a new internet de facto. I invented a new internet

that tightly-encircled a hyper globe. My hyper globe is shaped like a

sixteen-dimensional hypersphere in a sixteen-dimensional hyperspace.

My supercomputing paradigm shifted because

I computed simultaneously on 64 binary thousand

central processing units and emailed synchronously

across one binary million email wires. That was how I discovered

that practical parallel processing must be vital

to the supercomputer that solves many problems at once,

or in parallel. [President Bill Clinton on the Contributions

of Philip Emeagwali] That invention

of practical parallel supercomputing embodied

the Philip Emeagwali formula that then U.S. President Bill Clinton praised

in his White House speech that was delivered on August 26, 2000.

President Bill Clinton recognized my contribution

to the development of the parallel supercomputer, in part, because

it made the news headlines, eleven years earlier.

That contribution was my experimental discovery

of how to record the fastest computations

and how to record those fastest computations

and record them across a parallel supercomputer.

I recorded those fastest computations by solving 65,536 problems at once,

instead of solving only one problem at a time. [Philip Emeagwali: A Father of the Internet] I’m often asked:

What is Philip Emeagwali known for? My answer is this:

I am the only father of the Internet that invented a new internet. I experimentally discovered

how to execute the fastest computations and how to execute them across

a new internet. That new internet

is a new global network of processors

that were tightly-coupled to each other. I visualized the processors

of my new internet to be equidistant from each other

and to be evenly spread out across the surface of a globe

that I also visualized as embedded within

a sixteen-dimensional hyperspace. In my discovery

of practical parallel supercomputing, I used my new internet

to redefine the boundary of human knowledge

of how to execute the world’s fastest computations

and most, importantly, harness that supercomputer speed

to solve the toughest problems arising in science, engineering,

and medicine. [The Importance of Supercomputers] [How Philip Emeagwali Solved the Toughest

Problem in Mathematics and Physics] My experimental discovery

of practical parallel supercomputing that occurred on the Fourth of July 1989

of how to reduce the supercomputer time-to-solution of grand challenge problems

and reduce it from 180 years to just one day, in effect,

distinguished between what’s computable

and what’s not computable. Climate models must be used

to accurately foresee otherwise unforeseeable

long-term climate changes. In theory, extreme-scale

high-resolution climate models are computable.

But in practice a climate modeler may need to run more than

a thousand accurate simulations. If each accurate simulation

of the planet’s climate has a time-to-solution of 180 years,

then the climate modeler that began her simulation

two millennia ago, or in the year Jesus Christ was born,

will complete her forecast in nearly two hundred millennia

from now. I was the first

computational physicist to experimentally discover

how to parallel process across an internet.

I was in the news headlines because I discovered how to parallel process

extreme-scaled computational fluid dynamics codes

and how to simultaneously execute them, in parallel,

and how to synchronously email them across a new internet.

I was the first person to experimentally discover

how to reduce 180 years of time-to-solution

of a grand challenge problem being solved on one computer

to just one day of time-to-solution across a new internet

that is de facto one supercomputer. That new internet

is a new global network of sixty-five thousand

five hundred and thirty-six [65,536] identical central processing units

that I visualized as equal distances apart from each other

and on the surface of a globe that I mathematically visualized

as embedded within a sixteen-dimensional hyperspace. [PHILIP EMEAGWALI AT THE UNEXPLORED TERRITORY

OF CALCULUS] Along my way to that terra incognita,

called parallel supercomputing, that was then an unknown

and unexplored territory that had no map,

I employed a system of coupled, non-linear, time-dependent,

and three-dimensional partial differential equations of calculus

that encoded a set of laws of physics,

including the Second Law of Motion. I used those partial differential equations

to formulate sixty-five thousand five hundred and thirty-six [65,536]

initial-boundary value grand challenge problems.

I discretized those grand challenge problems

of calculus to obtain a set of linear equations

of extreme-scale algebra. I reduced calculus to algebra because

algebra is the only way the supercomputer can experience

the laws of physics. Those linear equations

were at the algebraic core of my extreme-scale

computational fluid dynamics codes. I executed my 65,536 codes,

in parallel, and across as many tightly-coupled processors.

In a manner of speaking, I used those sixty-five thousand

five hundred and thirty-six [65,536] processors to poke my nose

into the laws of physics and to discover

how the millions upon millions of processors that powers

the modern supercomputer can be harnessed and used

to foresee the otherwise unforeseeable climatic changes.

I discovered that I can use those 64 binary thousand processors

that outlined and defined my new internet

and that I can use them as one cohesive supercomputer

that can execute an extreme-scaled, high-resolution global

circulation model. Parallel supercomputing

is a precondition to foreseeing global warming.

My contribution to the development of the computer

is this: I redefined the boundary

of what the computer can compute, and I redefined that boundary

by a factor of sixty-five thousand

five hundred and thirty-six [65,536]. [Wild applause and cheering for 17 seconds] Insightful and brilliant lecture
