To elaborate a bit, there are planned to be at least 3 exascale computers running by the end of 2021, that I am aware of (1 in China and 2 in the US), with Frontier at ORNL estimated to provide about 3x the compute power of LUMI. It’s good to see the supercomputer arms race going strong. There are so many problems in the physical sciences that just can’t be solved without larger and larger supercomputer-style clusters. I know this is a kind of ill-formed question, but does anyone in the neuro or bio fields know how far away we are from being able to convincingly simulate a brain (human or other mammal), in terms of raw compute power?
