The US nuclear arsenal relies on a new supercomputer



In Livermore, California, in a sumptuous, white-tiled room, Sierra is the second most powerful supercomputer in the world. Sierra looks pretty much like a server farm, but it is not. And that message would not matter to the world if Sierra did not become the machine that controls the US nuclear arsenal.

According to The Verge, Sierra is a massively connected hive with 190,000 processor cores, all working together to accomplish the same tasks. Currently, this supercomputer is only used for simulations such as astrophysics, climate models and precision medicine simulations. This allows researchers to calibrate the device, test the performance, and troubleshoot any technical issues that may arise.

9, Sierra's supercomputer will do its actual job of controlling the US nuclear arsenal. The entire system will be "air-filled" so that it would not be connected to external networks or the Internet to prevent any unauthorized outside access.

The US nuclear arsenal relies on a new supercomputer The Sierra supercomputer would perform calculations and simulations of nuclear weapons and detonations. What Sierra would simulate, however, is classified so that we do not know (and probably will never find out) what Sierra's job would actually be.

Since the Divider-Nuke 50 years ago, the United States has done no new atom bomb testing or construction. As we already know, the US has not fully disarmed its weapons, and according to some statistics, Americans have 4,000 nuclear warheads available each year, while Russia has about 4,300.

Nuclear testing is out of the question for environmental reasons The US Department of Defense needed other safeguards to verify the effectiveness of the US nuclear arsenal, which had already run its course. For this reason, Sierra's supercomputer is indispensable for the simulation of atomic bombardments and detonations.

Fortunately, Verge's tech news portal was at the Lawrence Livermore National Laboratory, where the Sierra Supercomputer is present a video:
