SUMMARY

The total computing power of all computers on Earth is estimated to be around 10^18 FLOPS (floating-point operations per second). This immense computational capacity could theoretically simulate a biological brain with approximately 100 billion neurons, similar to the human brain. However, simulating a brain with 500 billion neurons would require significantly more resources, potentially exceeding current global computing capabilities. This discussion highlights the relevance of Fermi problems in estimating complex systems.

PREREQUISITES
  • Understanding of FLOPS (floating-point operations per second)
  • Basic knowledge of neural networks and brain structure
  • Familiarity with computational modeling techniques
  • Awareness of Fermi problems and estimation methods
NEXT STEPS
  • Research the latest advancements in neural network simulations
  • Explore the concept of Fermi problems in scientific estimation
  • Investigate the computational requirements for simulating large-scale neural networks
  • Learn about the current state of supercomputing technology and its applications
USEFUL FOR

Researchers in neuroscience, computer scientists focused on artificial intelligence, and anyone interested in the intersection of computing power and biological simulation.

Does anyone know of a good estimate of the computing power of all the computers that are on Earth and running.

Do you know how large of a biological brain it would be possible to simulate with all this computing power (eg. 100 billion neurons, 500 billion neurons, ect.)? It seems like it would be possible to simulate like a super huge brain with as much computing power as there is on the planet.

sounds like a "fermi problem"...
