Memristors -- from In-memory computing, Deep Learning Acceleration, Spiking Neural Networks, to the Future of Neuromorphic and Bio-inspired Computing
Machine learning, particularly in the form of deep learning, has driven most
of the recent fundamental developments in artificial intelligence. Deep
learning is based on computational models that are, to a certain extent,
bio-inspired, as they rely on networks of connected simple computing units
operating in parallel. Deep learning has been successfully applied in areas
such as object/pattern recognition, speech and natural language processing,
self-driving vehicles, intelligent self-diagnostics tools, autonomous robots,
knowledgeable personal assistants, and monitoring. These successes have been
mostly supported by three factors: availability of vast amounts of data,
continuous growth in computing power, and algorithmic innovations. The
approaching demise of Moore's law, and the consequent expected modest
improvements in computing power that can be achieved by scaling, raise the
question of whether the described progress will be slowed or halted due to
hardware limitations. This paper reviews the case for a novel beyond CMOS
hardware technology, memristors, as a potential solution for the implementation
of power-efficient in-memory computing, deep learning accelerators, and spiking
neural networks. Central themes are the reliance on non-von-Neumann computing
architectures and the need for developing tailored learning and inference
algorithms. To argue that lessons from biology can be useful in providing
directions for further progress in artificial intelligence, we briefly discuss
an example based reservoir computing. We conclude the review by speculating on
the big picture view of future neuromorphic and brain-inspired computing
systems.Comment: Keywords: memristor, neuromorphic, AI, deep learning, spiking neural

2022 roadmap on neuromorphic computing and engineering
Modern computation based on von Neumann architecture is now a mature cutting-edge science. In the von Neumann architecture, processing and memory units are implemented as separate blocks interchanging data intensively and continuously. This data transfer is responsible for a large part of the power consumption. The next generation computer technology is expected to solve problems at the exascale with 10 calculations each second. Even though these future computers will be incredibly powerful, if they are based on von Neumann type architectures, they will consume between 20 and 30 megawatts of power and will not have intrinsic physically built-in capabilities to learn or deal with complex data as our brain does. These needs can be addressed by neuromorphic computing systems which are inspired by the biological concepts of the human brain. This new generation of computers has the potential to be used for the storage and processing of large amounts of digital information with much lower power consumption than conventional processors. Among their potential future applications, an important niche is moving the control from data centers to edge devices. The aim of this roadmap is to present a snapshot of the present state of neuromorphic technology and provide an opinion on the challenges and opportunities that the future holds in the major areas of neuromorphic technology, namely materials, devices, neuromorphic circuits, neuromorphic algorithms, applications, and ethics. The roadmap is a collection of perspectives where leading researchers in the neuromorphic community provide their own view about the current state and the future challenges for each research area. We hope that this roadmap will be a useful resource by providing a concise yet comprehensive introduction to readers outside this field, for those who are just entering the field, as well as providing future perspectives for those who are well established in the neuromorphic computing community
Solution of partial differential equations on vector and parallel computers
The present status of numerical methods for partial differential equations on vector and parallel computers was reviewed. The relevant aspects of these computers are discussed and a brief review of their development is included, with particular attention paid to those characteristics that influence algorithm selection. Both direct and iterative methods are given for elliptic equations as well as explicit and implicit methods for initial boundary value problems. The intent is to point out attractive methods as well as areas where this class of computer architecture cannot be fully utilized because of either hardware restrictions or the lack of adequate algorithms. Application areas utilizing these computers are briefly discussed
