Philip Emeagwali (born 23 August 1954) is a computer scientist originally from Nigeria. [1] He won the 1989 Gordon Bell Prize for price-performance in high-performance computing applications, in an oil reservoir modeling calculation using a novel mathematical formulation and implementation. [2] He is known for making controversial claims about his achievements that are disputed by the scientific community. [3]

Biography

Philip Emeagwali was born in Akure, Nigeria on 23 August 1954. [4] He was raised in Onitsha in the South Eastern part of Nigeria. His early schooling was suspended in 1967 as a result of the Nigerian Civil War. At age 13, he worked in the Biafran army. After the war he completed high-school equivalence through self-study. [5]

Later on he married Dale Brown Emeagwali, an African-American microbiologist. [6]

Education

He traveled to the United States to study under a scholarship following completion of a course at the University of London. He received a bachelor's degree in mathematics from Oregon State University in 1977. [7] He later moved to Washington D.C., receiving in 1986 a master's degree from George Washington University in ocean and marine engineering, and a second master's in applied mathematics from the University of Maryland. [8] Next magazine suggested that Emeagwali claimed to have further degrees. [9] [10] During this time, he worked as a civil engineer at the Bureau of Land Reclamation in Wyoming.

Court case and the denial of degree

Emeagwali studied for a Ph.D. degree from the University of Michigan from 1987 through 1991. His thesis was not accepted by a committee of internal and external examiners and thus he was not awarded the degree. [11] Emeagwali filed a court challenge, stating that the decision was a violation of his civil rights and that the university had discriminated against him in several ways because of his race. The court challenge was dismissed, as was an appeal to the Michigan state Court of Appeals. [12] [13] [14]

Supercomputing

Emeagwali received the 1989 Gordon Bell Prize [2] [15] for an application of the CM-2 massively-parallel computer. The application used computational fluid dynamics for oil-reservoir modeling. He received a prize in "price/performance" category, with a performance figure of about 400 Mflops/$1M.[ citation needed ] The winner in the "performance" category was also the winner of the Price/performance category, but unable to receive two prizes: Mobil Research and Thinking Machines used the CM-2 for seismic data processing and achieved the higher ratio of 500 Mflops/$1M. The judges decided on one award per entry.[ citation needed ] His method involved each microprocessor communicating with six neighbors. [10]

Emeagwali's simulation was the first program to apply a pseudo-time approach to reservoir modeling. He was cited by Bill Clinton as an example of what Nigerians can achieve when given the opportunity [16] and is frequently featured in popular press articles for Black History Month. [17] [10]

Debunked controversial claims

Emeagwali has made several controversial claims about his achievements that are disputed by the scientific community. His claim of being a father of the Internet, of having invented the Connection Machine, of possessing 41 patented inventions, of winning "the Nobel Prize of Computing" and of being a "doctor" and/or "professor" have been conclusively debunked with widely documented evidence. [3] Speaking during a visit to Switzerland in April 2009, Mr. Emeagwali said he was the first to program a hypercube "to solve a grand challenge defined as the 20 gold-ring problems in computing. That discovery, in part, inspired the reinvention of supercomputers as an Internet." He claimed that by his effort, he was able to set three world records and improve on Newton's second law of motion. [18]

<span class="mw-page-title-main">Supercomputer</span> Type of extremely powerful computer

A supercomputer is a type of computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, supercomputers have existed which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS). For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers.

Floating point operations per second is a measure of computer performance in computing, useful in fields of scientific computations that require floating-point calculations.

In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. This rate is typically measured by performance on the LINPACK benchmark when trying to compare between computing systems: an example using this is the Green500 list of supercomputers. Performance per watt has been suggested to be a more sustainable measure of computing than Moore's Law.

The FETI-DP method is a domain decomposition method that enforces equality of the solution at subdomain interfaces by Lagrange multipliers except at subdomain corners, which remain primal variables. The first mathematical analysis of the method was provided by Mandel and Tezaur. The method was further improved by enforcing the equality of averages across the edges or faces on subdomain interfaces which is important for parallel scalability for 3D problems. FETI-DP is a simplification and a better performing version of FETI. The eigenvalues of FETI-DP are same as those of BDDC, except for the eigenvalue equal to one, and so the performance of FETI-DP and BDDC is essentially same.
