Before You Can Simulate the Universe, You Have to Map It

Perlmutter is named after Berkeley Lab’s Nobel

A powerful supercomputer will use artificial intelligence to map the universe in 3-D:

The real power of Perlmutter, Dr. Bailey said, will come into play as the data starts to build up and researchers begin creating maps to judge their progress. Processing a year’s worth of the data, for example, would take weeks with an existing supercomputer, Dr. Bailey said.

However, Perlmutter—which will be shared with other research teams working on other scientific projects—should be able to accomplish the task in a matter of days...

HPE says the NERSC computer has a peak AI performance, or speed, of almost four “AI exaflops,” which the company said would make the machine the fastest AI supercomputer to date. An AI exaflop is roughly mathematically equivalent to performing 250 petaflops per second, it said. A petaflop is 1,000 trillion, or one quadrillion, operations per second.

Today's smartphone is more powerful than all of NASA's computers used for the moon landing. Perlmutter will seem as primitive to data scientists 50 years from now as NASA's computers appear to us today.

Given the speed that computing power is progressing, we may soon have the power to populate this 3-D map of the universe with beings who think they are "conscious." Of course, that doesn't have to mean anything about our world.
