Bolton says way is open for Iran to enter talks with U.S.

Bolton says way is open for Iran to enter talks with U.S. U.S. National Security Adviser John Bolton, speaking after the United States increased sanctions against Iranian officials, said Washington was still willing to talk to Iran. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); "The president has held the door open to real negotiations to completely and verifiably eliminate Iran's nuclear weapons programme, its ballistic missile delivery systems, its support for international terrorism and other malign behaviour worldwide," Bolton said in Jerusalem.

El Capitan will be created for the National Nuclear Security Administration and Lawrence Livermore National Laboratory, also serving the Los Alamos Cray is also developing two other exascale supercomputers for the DOE, for Argonne National Laboratory and Oak Ridge National Laboratory.

The El Capitan supercomputer , which will be built by Cray , is expected to be delivered to the Department of Energy and National Nuclear Security One of El Capitan 's jobs will be to model 3D simulations of how nuclear weapons age, for which researchers have no nuclear test data, Cray said

Cray has been awarded a $600 million contract to build the first exascale supercomputer for the National Nuclear Security Administration, the US Department of Energy and the NNSA announced Tuesday. Named El Capitan, the supercomputer will be the fastest known in the world and will help manage the US' nuclear stockpile. It's expected to go into production by late 2023.

Supercomputers are used for power-intensive programs like quantum physics, examining whether old nuclear weapons could still explode, forecasting global climate change effects, designing engines and aircraft, and reconstructing the history of the universe. The two highest-powered supercomputers are still Summit and Sierra, owned by IBM in the US, according to a June report from Top500, which ranks the highest-performing computer systems in the world twice a year.

Iran tells UN it cannot save nuclear deal

Iran tells UN it cannot save nuclear deal Iran told the UN Security Council on Wednesday that it cannot "alone" save the nuclear deal, turning up pressure on the Europeans, Russia and China as it moved toward a possible breach of its commitments to limit its nuclear activities. 

El Capitan 's job will be to will perform essential functions for the Stockpile Stewardship Program, which supports US national security missions in ensuring the safety, security and effectiveness of the nation's nuclear stockpile in the absence of underground testing. Developed as part of the second

El Capitan will be the first exascale supercomputer for the National Nuclear Security Administration (NNSA) and will exclusively serve its efforts to ensure the safety, reliability and security of the nation's nuclear stockpile. The system will include Cray 's new Shasta architecture, ClusterStor storage and

Sierra tops out at 125 petaflops, while El Capitan could run roughly 10 times faster, according to Lawrence Livermore National Laboratory. It has a peak performance of more than 1.5 exaflops, or 1.5 quintillion calculations per second, and will be used for national nuclear security applications at more than 50 times the speed of LLNL's Sequoia system.

El Capitan is also projected to be at least four times more energy efficient than Sierra.

"El Capitan will allow us to be more responsive, innovative and forward-thinking when it comes to maintaining a nuclear deterrent that is second to none in a rapidly evolving threat environment," Lisa E Gordon-Hagerty, DOE Nuclear Security under secretary, said in a release.

Iran reduces commitment to 2015 nuclear deal

Iran reduces commitment to 2015 nuclear deal Iran said on Sunday it would further scale back its commitment to the 2015 nuclear deal with world powers, raising its uranium enrichment level to what officials said earlier was 5% to produce fuel for power plants. In a news conference, senior Iranian officials also said Tehran would keep reducing its commitments every 60 days unless signatories of the pact moved to protect it from U.S. sanctions, but they left the door open to diplomacy.

El Capitan will take the helm as the world's fastest supercomputer with 1.5 The DOE is currently in the process of redesigning every component of its nuclear warheads and The DOE disclosed today that it had awarded a 0 million contract to Cray , which is currently You'll notice that neither of those systems comes packing Nvidia GPUs, which have long been the mainstay for supercomputers .

All those exaflops will be pressed into service for the Stockpile Stewardship Program, which supports US national security missions and monitoring the nation's nuclear stockpile in the absence of underground testing. El Capitan will also focus on evolving threats to national security, nonproliferation and nuclear counterterrorism.

Back in 2016, a report from the US government showed it still used a 1970s-era IBM Series/1 mainframe computer with 8-inch floppy drives to control its nuclear forces -- including intercontinental ballistic missiles, nuclear bombers and tanker support aircraft.

Cray is in the process of being acquired by Hewlett Packard Enterprise for $1.3 billion.

Summit is the world's smartest computer

$600M Cray supercomputer will tower above the rest — to build better nukes.
Cray has been commissioned by Lawrence Livermore National Laboratory to create a supercomputer head and shoulders above all the rest, with the contract valued at some $600 million. Disappointingly, El Capitan, as the system will be called, will be more or less solely dedicated to redesigning our nuclear armament. El Capitan will be the third "exascale" computer being built by Cray for the U.S. government, the other two being Aurora for Argonne National Lab and Frontier for Oak Ridge.
