how was the computer built by the united states able to help the war effort? This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you The new supercomputer behind the US nuclear arsenal. Following along are instructions in the video below:
Electronic tune william this is the second most powerful supercomputer on the planet. It is is 7000 square feet of racks wires and blinking lights. It has a few hundred times more punch than your laptop its name is sierra computer music the computer is housed at the lawrence livermore national laboratory.
Just east of the san francisco bay. Its been up and running for most of 2018. But the lab just recently held an official dedication for it and we checked it out we took a tour of the computer room.
We got commemorative coins and experts told us all about the exciting work that sierras been doing. Its been modeling earthquakes doing cancer simulations. Exploring traumatic brain injuries and a lot more and then howdy william we were all greeted by rick perry.
The secretary of energy for the united states to the countless engineers and the technicians. The electricians designers and code developers who made sierra a reality america applauds your magnificent achievement. Applause that happened because early next year sierra will be air gapped that means that itll be completely cut off from any computer network.
And it will mostly stop studying earthquakes and brain injuries. Itll turn into a little island of processing power. And its operations will be classified.
And thats when its real job. Begins. Computer music sierras story begins in 1992 with the last nuclear bomb.
The united states ever tested called divider.
The bomb capped off almost 50 years of nuclear weapons. Tests. And more than 1000.
Explosions. Since then the us has neither tested. A nuke nor designed any entirely new warheads this is thanks in part to a landmark nonproliferation treaty signed by most of the world back in 1970 among other things the treaty called for an end to the arms race and a good faith effort to reach complete disarmament.
Theres been a lot of progress since then and today. The global stockpile is maybe a sixth of what it was in the80s. But of course.
The us never did disarm entirely. Neither did russia or most other nuclear nations today. The united states maintains a stockpile of about 4000 aging.
Yet untestable nuclear weapons. Which leaves the government in a bind. When they were built they werent intended to last for 30 to 40 or even 50 years.
We were on a cycle of replacing weapons on a regular schedule. A decade or two in the stockpile would be kind of average william brian pudliner is a code physicist at the livermore lab and starting next year. Hes going to use sierra to tackle this catch.
22 in our defense policy as nuclear weapons age past their lifespan their reliability becomes suspect.
But with testing out of the question. Its harder and harder to answer basic. But scary questions about our arsenal.
If we ever had to use a 40 year old nuclear missile would it launch properly would it reach its target would it explode. The things that were concerned about is exactly that the performance from using the weapon. But also in transporting.
The weapon how its stored will it be safe if it falls into the wrong hands will its safety. Features keep it from being used sierra is the latest answer to that problem all those stacks of processors can simulate questions. The military might have about its arsenal.
Exactly what questions thats classified. But as the weapons age parts degrade and need to be repaired or swapped out this could be anything from the weapons enclosure to the core of plutonium sitting inside sierras job will be to model these changes and run simulations to predict whether anything would break in a real world detonation and that job. It gets harder the older.
The bombs are as the weapons age. And we have to refurbish them to keep them alive for longer we keep making more and more changes that take them further and further away from what was tested one example is the w80 warhead. They were manufactured as far back as the early 1980s and the military hopes to keep them online for years to come.
But they need work the conventional explosives used to trigger the bombs fission stage. Need to be replaced. But those original compounds have been retired sierra needs to simulate new explosives until it finds one that we can trust with a real detonation.
One that hopefully will never happen sierras work falls under the governments stockpile stewardship program over the years.
The program has included 12. Other supercomputers. The worlds largest laser.
And even explosive tests. Alert sound using plutonium crash just not enough for a full nuclear. Chain reaction.
We wanted an outside take on all of this. So. We called daryl kimball.
The executive director of the arms control association. Hes glad that there are no more live nuclear tests. But he hasnt forgotten that big treaty from 1970.
That commitment to disarm if the united states today 50 years later is continuing to seek to maintain its existing stockpile and in some ways. Improve and upgrade. It as we are now i see that as fundamentally incompatible in the long run with our legal obligation to pursue nuclear.
Disarmament daryl pointed to a nuclear posture review that the trump administration published this year. He says that the review is bullish on new nuclear capabilities for the military which means the line could further blur between maintaining old weapons and turning them into new ones. The door is open in the sense.
That you know we dont have a hard and fast policy against new nuclear.
Warhead designs. This research could in my view go in the wrong direction. If the policymakers in washington allow it to william the researchers at lawrence livermore.
They dont wade too far into that debate. What we do is we answer questions for the department of energy william terri. Quinn runs livermores entire computing center and to her stockpile stewardship is specific and practical we get requirements from the military as to what they want these weapons to do and then we do the analysis of it and whatever experiments and testing.
We can do and we run things on computers and then we give them answers back they make the decisions. Were here as really scientific and technical experts to answer those questions the need for supercomputers isnt going anywhere and sierras successor el capitan is already in the works. Itll be another huge leap forward and another supercomputer reserved for the military and they want to do even more complex 3 d problems.
And many many many more of them than we believe that we can do on sierra and well need something thats at least an order of magnitude. Which is 10 times bigger in order to carry out those calculations william for now. Livermores other science work the earthquake simulations the precision medicine.
The astrophysics itll still happen here and there at sierra. If theres time. The weapons come first as long as we have nuclear weapons.
We will need simulation being able to predict you know if this weapon is around for a hundred years. What happens is going to be something that well be working on for a while computer music for what its worth. The number one most powerful supercomputer on the planet is called summit and its at the oak ridge national laboratory in tennessee.
It has a similar architecture to sierra. But its unclassified so it spends all its time on biology and astrophysics basically all the civilian stuff. .
