Computer
crashes may soon be a thing of the past, thanks to new research by University
College London computer scientists Peter Bentley and Christos Sakellariou.
They've created a crash-proof computer by introducing chaos and randomness:
OUT of chaos, comes order. A computer that mimics the apparent randomness
found in nature can instantly recover from crashes by repairing corrupted
data.
Dubbed a "systemic" computer, the self-repairing machine
now operating at University College London (UCL) could keep mission-critical
systems working. For instance, it could allow drones to reprogram themselves
to cope with combat damage, or help create more realistic models of
the human brain.
Everyday computers are ill suited to modelling natural processes such
as how neurons work or how bees swarm. This is because they plod along
sequentially, executing one instruction at a time. "Nature isn't
like that," says UCL computer scientist Peter Bentley. "Its
processes are distributed, decentralised and probabilistic. And they
are fault tolerant, able to heal themselves. A computer should be able
to do that."
