Intro topic · Computer scientist Philip Emeagwali's inspiration and work on parallel computing

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

Describe Emeagwali's contribution · Developed parallel computing system to predict underground oil flow

Used network of many computers working simultaneously; solved speed and efficiency problems with traditional "sequential" computers

Problem · Predicting oil flow requires many simultaneous calculations

New problem and solution · Properly dividing parallel tasks is hard; solution was to design computer network like tree branches

Tree branches follow very efficient patterns for collecting and moving resources; computer networks that follow the same underlying patterns are very efficient at generating and transmitting data

Emeagwali's future work · Parallel computing modeled after spacing of honeycombs

Emeagwali's perspective · Nature will become a more important source of inspiration for technical solutions

According to the passage, which ███ ██ ███ █████████ ██ █████

Emeagwali's breakthroughs in ████████ ██████ ████ █████ ██ ████ █████████ ████ ████ ████████████ █████████

“Obsolete” is not supported. The author never indicates that Emeagwali’s breakthroughs have begun to make sequential computers obsolete.

Emeagwali's first breakthrough ██ ████████ ██████ ████ ██ ████████ ██ █ ███████ ██ ██ ███ ████████

We don’t know that this was Emeagwali’s “first” breakthrough, or that this design came in response to a request.

Emeagwali was the █████ ██ ███ █ █████████ ████████ ████████ ██ ███████ ███ ████ ██ ███ ██ ███ ███████

Supported, because Emeagwali “pioneered” the use of parallel computing to model oil field flow.

90%

Emeagwali was the █████ ████████ █████████ ██ ███ ██████ ██ █ █████ ███ █████ ███████████

We don’t know that he was the first to use nature as a model for technology. He may have been the first to apply parallel computing to oil fields, but this doesn’t imply he was the first to look to nature as a model for technology.

Emeagwali was the █████ ██ █████ ████████ ██████████ ██ ███████ ██████████ █████████

We don’t know that he was the first to use parallel processing to solve real-world problems. He may have been the first to apply parallel computing to oil fields, but this doesn’t imply he was the first to use parallel processing to solve real-world problems.
