Benchmarking Brian2 on M1

Announcements
1

Dear all,
A friend of mine got working docker on the M1 processor and ran a few benchmarks both on top Intel processors (available on Mac) and on M1. The benchmarks are from the paper Tikidji-Hamburyan et al. 2015 Software for Brain Network Simulations: A Comparative Study and were slightly modified compared with the original version.

Hardware

  • MacMini Intel(R) Core™ i7-8700B CPU @ 3.20GHz (6C 12T) 64GB RAM
    Docker 12C 16GB RAM
  • MacBook Pro 13" M1 16GB
    Docker 8C 10GB RAM

Results for the single thread
Testing 10 times: 5000 leaky integrate-and-fire neurons with random connections
