Questions tagged [exascale]

Exascale refers to the ability to realize ${10}^{18}$ floating point operations per second. While this threshold has not yet been reached, many researchers are currently working to develop ways to create exaflop machines, and potential programming paradigms to use them efficiently.

Is a complete bacteria simulation with an exascale supercomputer possible?

Will it be possible to simulate a complete (at least simple) bacteria atom by atom on an exascale supercomputer? or is it possible already today with the largest systems? Here, I've read that ...

What programming paradigms should I be investing in if I want my code to run on petascale machines in the future?

It's pretty clear from a survey of the top500 that the industry is trending towards an exponential increase in processing cores. The largest supercomputers all use MPI for communication between nodes,...
