Supercomputers are machines that, as of 2015, could compute quadrillions of floating-point operations per second. That is, their performance is multiples of 1015 operations per second. These machines are used for a variety of things, including simulating earthquakes, nuclear reactions, and the big bang.

In fact, supercomputer simulations have at this point replaced the testing of actual nuclear arms. Some of the advantages to these simulations include:

Select TWO answers.


Models can incorporate all of the complexities of nuclear reactions.


Models are cheaper than building multiple designs and testing each in the real world.


Modern supercomputers are cheaper than a mid-size car.


Simulations come without the environmental risks associated with nuclear tests.
