# Kunle Olukotun

Oyekunle Ayinde "Kunle" Olukotun is a British-born Nigerian computer scientist who is the Cadence Design Systems Professor of the Stanford School of Engineering, Professor of Electrical Engineering and Computer Science at Stanford University and the director of the Stanford Pervasive Parallelism Lab. Olukotun is known as the “father of the multi-core processor”, and the leader of the Stanford Hydra Chip Multiprocessor research project. Olukotun's achievements include designing the first general-purpose multi-core CPU, innovating single-chip multiprocessor and multi-threaded processor design, and pioneering multicore CPUs and GPUs, transactional memory technology and domain-specific languages programming models. Olukotun's research interests include computer architecture, parallel programming environments and scalable parallel systems, domain specific languages and high-level compilers.

## Education

Olukotun did his undergraduate studies at Calvin College, in Grand Rapids, Michigan. He earned an MS (1987) and PhD (1991) from University of Michigan, in Computer Science and Engineering. His advisor was Trevor Mudge.

## Career

Olukotun joined Stanford's Department of Electrical Engineering in 1991. While at Stanford, Olukotun became the leader of the Stanford Hydra chip multiprocessor (CMP) research project which allowed for the development of multiprocessors with support for thread-level speculation. In 2000, he founded Afara Websystems, a company that designed and manufactured high-throughput, low power processors for server systems with chip multiprocessor technology. Afara was purchased by Sun Microsystems in 2002. The Afara multicore processor Niagara, developed by Olukotun was acquired by Sun. Niagara derived processors currently power all Oracle SPARC-based servers and have generated billions of dollars of revenue. While at Sun, Olukotun was one of the architects of the 2005 UltraSPARC T1 processor.
In 2017 Olukotun and Chris Ré founded SambaNova Systems. SambaNova Systems is developing a next-generation computing platform to power machine learning and data analytics. Olukotun now leads the Stanford Pervasive Parallelism Lab, which focuses on making heterogeneous parallel computing easy to use, and he is a member of the Data Analytics for What’s Next (DAWN) Lab, which is developing infrastructure for usable machine learning.

## Research

Olukotun's research focus is in computer architecture, parallel programming environments and scalable parallel systems, domain specific languages, and high-level compilers.
Olukotun leads the Stanford Hydra chip multiprocessor (CMP) research project, revolutionizing computing by bringing multi-core technology to consumers and high-end computing systems.
In the mid-1990s, Olukotun and his co-authors argued that multi-core computer processors were likely to make better use of hardware than existing superscalar designs.
In 2008, Olukotun returned to Stanford, and founded the Pervasive Parallelism Laboratory at Stanford after gathering US$6 million in funding from several computer-industry corporations. His recent work focuses on domain-specific programming languages that can allow algorithms to be easily adapted to multiple different types of parallel hardware including multi-core systems, graphics processing units, and field-programmable gate arrays.
Olukotun is also a member of the board of advisors of UDC, a Nigerian venture capital firm. He was elected as a Fellow of the Association for Computing Machinery in 2006 for his "contributions to multiprocessors on a chip and multi threaded processor design". He became a Fellow of the IEEE in 2008.
Olukotun has used several words from his Yoruba heritage in his research. Afara, the name of the company he founded, means "bridge" in the Yoruba language, and he has named his server at Stanford Ogun after the Yoruba god of iron and steel, a play on words since large computers are frequently called big iron.
Olukotun directs the Stanford Pervasive Parallelism Lab (PPL) which seeks to proliferate the use of parallelism in all application areas. He is also a member of the Data Analytics for What's Next (DAWN) Lab.
Olukotun holds 12 U.S. patents. He has published more than 150 scientific papers and wrote two textbooks.
