Self-managing systems, whether viewed from the perspective of Autonomic Computing, or from that of another initiative, offers a holistic vision for the development and evolution of biologically-inspired computer-based systems. It aims to bring new levels of automation and dependability to systems, while simultaneously hiding their complexity and reducing costs. A case can certainly be made that all computer-based systems should exhibit autonomic properties [6], and we envisage greater interest in, and uptake of, autonomic principles in future system development
A new paradigm for SpeckNets:inspiration from fungal colonies
In this position paper, we propose the development of a new biologically inspired paradigm based on fungal colonies, for the application to pervasive adaptive systems. Fungal colonies have a number of properties that make them an excellent candidate for inspiration for engineered systems. Here we propose the application of such inspiration to a speckled computing platform. We argue that properties from fungal colonies map well to properties and requirements for controlling SpeckNets and suggest that an existing mathematical model of a fungal colony can developed into a new computational paradigm
Stability and Memory-loss go Hand-in-Hand: Three Results in Dynamics & Computation
The search for universal laws that help establish a relationship between
dynamics and computation is driven by recent expansionist initiatives in
biologically inspired computing. A general setting to understand both such
dynamics and computation is a driven dynamical system that responds to a
temporal input. Surprisingly, we find memory-loss a feature of driven systems
to forget their internal states helps provide unambiguous answers to the
following fundamental stability questions that have been unanswered for
decades: what is necessary and sufficient so that slightly different inputs
still lead to mostly similar responses? How does changing the driven system's
parameters affect stability? What is the mathematical definition of the
edge-of-criticality? We anticipate our results to be timely in understanding
and designing biologically inspired computers that are entering an era of
dedicated hardware implementations for neuromorphic computing and
state-of-the-art reservoir computing applications.Comment: To appear in the Proceedings of the Royal Society of London, Series
High-Speed CMOS-Free Purely Spintronic Asynchronous Recurrent Neural Network
Neuromorphic computing systems overcome the limitations of traditional von
Neumann computing architectures. These computing systems can be further
improved upon by using emerging technologies that are more efficient than CMOS
for neural computation. Recent research has demonstrated memristors and
spintronic devices in various neural network designs boost efficiency and
speed. This paper presents a biologically inspired fully spintronic neuron used
in a fully spintronic Hopfield RNN. The network is used to solve tasks, and the
results are compared against those of current Hopfield neuromorphic
architectures which use emerging technologies
Building a Spiking Neural Network Model of the Basal Ganglia on SpiNNaker
We present a biologically-inspired and scalable model of the Basal Ganglia (BG) simulated on the SpiNNaker machine, a biologically-inspired low-power hardware platform allowing parallel, asynchronous computing. Our BG model consists of six cell populations, where the neuro-computational unit is a conductance-based Izhikevich spiking neuron; the number of neurons in each population is proportional to that reported in anatomical literature. This model is treated as a single-channel of action-selection in the BG, and is scaled-up to three channels with lateral cross-channel connections. When tested with two competing inputs, this three-channel model demonstrates action-selection behaviour. The SpiNNaker-based model is mapped exactly on to SpineML running on a conventional computer; both model responses show functional and qualitative similarity, thus validating the usability of SpiNNaker for simulating biologically-plausible networks. Furthermore, the SpiNNaker-based model simulates in real time for time-steps 1 ms; power dissipated during model execution is & #x2248;1.8 W
The self distributing virtual machine (SDVM): making computer clusters adaptive
The Self Distributing Virtual Machine (SDVM) is a middleware concept to form a parallel computing machine consisting of a any set of processing units, such as functional units in a processor or FPGA, processing units in a multiprocessor chip, or computers in a computer cluster. Its structure and functionality is biologically inspired aiming towards forming a combined workforce of independent units (āsitesā), each acting on the same set of simple rules.
The SDVM supports growing and shrinking the cluster at runtime as well as heterogeneous clusters. It uses the work-stealing principle to dynamically distribute the workload among all sites. The SDVMās energy management targets the health of all sites by adjusting their power states according to workload and temperature. Dynamic reassignment of the current workload facilitates a new energy policy which focuses on increasing the reliability of each site.
This paper presents the structure and the functionality of the SDVM.1st IFIP International Conference on Biologically Inspired Cooperative Computing - Mechatronics and Computer ClustersRed de Universidades con Carreras en InformƔtica (RedUNCI
