By reducing the time required for these studies, total costs also are reduced. All of this helps to ensure that the nation will never have to return to nuclear testing. Supercomputers such as Sequoia have allowed the United States to have confidence in its nuclear weapons stockpile over the 20 years since nuclear testing ended in The insight that comes from supercomputing simulations also is vital to addressing nonproliferation and counterterrorism issues as well as informing other national security decisions such as nuclear weapon policy and treaty agreements.
The improvements in affordability, performance, efficiency and size that Sequoia delivers will also enable a broader set of commercial customers to implement HPC for their competitive advantage.
Sequoia is primarily water cooled and consists of 96 racks; 98, compute nodes; 1. Department of Energy responsible for enhancing national security through the military application of nuclear science.

The SuperMUC system is also connected to powerful visualisation systems, including a large 4K stereoscopic power wall and a five-sided immersive artificial virtual-reality environment or CAVE for visualising 3D data sets from fields, including Earth science, astronomy and medicine.
German state-funded institutions are interested in SuperMUC machines because they have a requirement to source their electricity only from renewable sources, which requires lower power demands than before. IBM's scientists instead developed a hot-water cooling system, which directly cools active components in the system such as processors and memory modules with coolant temperatures that can reach as high as F, or 45C.
Some consumer PCs, including past products from Apple, have used water cooling — but the risks of leakage meant that they have been largely abandoned. Because a given volume of water can retain a higher amount of heat than the same volume of air, it makes a more efficient medium for heat transfer — but most companies solve that by pumping more air through the system to deliver the same effect without the risk of leaks.
