My name is Grigori Fursin. I am the CTO of dividiti,
Chief Scientist of the cTuning Foundation (non-profit research organization)
and the reproducible research evangelist.
I have an interdisciplinary background in computer engineering, physics, neural networks,
electronics and machine learning with a PhD in computer science from the
University of Edinburgh.
20 years ago my first R&D project to build semiconductor neural networks
for brain-inspired computer systems suffered from intolerably slow and
unreliable computer simulation. This motivated me to temporally change
my research directions and learn how to optimize and co-design
such a fast, energy-efficient and reliable software and hardware
which could enable sustainable AI research.
I then spent last 15 years directing computer systems research at the
University of Edinburgh, INRIA and Intel Exascale Lab, while closely collaborating
with ARM, General Motors, Google, Intel, STMicroelectronics and IBM.
During that time I prepared foundations and open-source research SDK
to enable self-optimizing and efficient software and hardware
from cloud servers and supercomputers to constrained mobile devices and IoT
now used by automotive, robotics, bio-tech, fintech and other industries.
Such systems continuously
and test themselves,
exchange design and optimization knowledge via CK live repo or P2P,
and use machine learning to automatically adapt SW and HW
at all levels to perform any given computation with a given data set in a most efficient way
in terms of execution time, energy usage, memory footprint, accuracy, resiliency, HW price and other associated costs and resources
(CPC'15 vision paper,
I now work with the CK consortium
to use my collaborative design and optimization methodology,
open-source tools, public repository of knowledge
and CK-powered open challenges and optimization competitions
to crowdsource benchmarking, multi-objective optimization and co-design of AI and other complex
applications across diverse hardware and data sets
(see CK-powered DNN crowd-tuning
and related Android app)
while dramatically accelerating knowledge discovery, reducing time to market
for the new technology, and boosting innovation in science and
After sharing all my artifacts and promoting collaborative R&D since 2007, I am now glad and honored
that my community-driven optimization approach helped motivate open, collaborative and reproducible
computer systems' research and experimentation,
initiate Artifact Evaluation at the premier ACM
conferences on parallel programming, architecture and code generation
(PPoPP,CGO,PACT,RTSS,SC), and encourage fellow researchers preserve, organize,
cross-link and share their code and data in a unified, reusable, customizable and reproducible way
artifacts and workflow shared in the CK format).
My techniques were published
in PLDI,MICRO,IJPP,CGO,TACO,CASES and DATE,
received CGO "test of time award",
helped enable world's first machine learning based
self-tuning compiler (MILEPOST GCC) and
establish cTuning foundation (non-profit R&D organization),
were included to mainline GCC, influenced Fujitsu,
received INRIA outstanding research award, and are being commercialized
by dividiti startup to collaboratively
optimize HPC libraries and complex DNN algorithms across diverse hardware and data sets.
In a longer term I am interested in using my interdisciplinary knowledge
and experience to continue leading challenging and innovative projects
related to AI, brain-inspired computing, bio-informatics, space exploration,
medicine, big data predictive analytics, Internet of Things and Exascale computing.
When I have a bit of spare time, I prefer to spend it with my lovely family,
as well as traveling, reading, discovering new cultures, playing football (soccer),
skiing, swimming, snorkeling, climbing and jogging.
