After months of work unpacking, installing, and deploying the various subsystems and supporting infrastructure, Los Alamos National Laboratory's (LANL) latest super, the Crossroads system, has been installed. This big beast is tasked with one of the US Department of Energy's (DoE) most secretive workloads: making sure America' …
I've predicted the Test Ban Treaty will eventually be scuttled since at some point in time there will be the necessity to develop a new warhead and you simply cannot be sure that it works as intended without actually setting one off. There will be enormous political pressure to test since the credibility of our deterrent is at stake.
Simulations are nice but they cannot replace a real-life test.
And that matters why ?
He's a nutjob building nukes, and the day he's got them, he won't be afraid of using them.
I just hope that NK is blanketed in spy sats watching his every move. The day he starts setting up a base to launch nuclear missiles, it should be destroyed without hesitation and without delay.
Tad bit late for that I think. NK has already demonstrated both nuclear weapons and ballistic missiles that work, at least some of the time.
I don't think even they are mad enough to attempt a live demonstration of the complete system, so I'll leave the speculation as to whether they could actually achieve that to the expert analysts...
The Comprehensive Test Ban Treaty also bans underground testing. Too bad the United States didn't ratify it and neither did China.
The CTBT is therefore only a pause in nuclear testing, not the definitive end. Note that Russia signed and ratified the treaty, but I doubt they'll keep abiding by it if anyone, especially the U.S., starts testing again.
For me the main take away message is how important the high-bandwidth memory Xeon Max will be in high-performance computing. This is explained in the quote by Grider that "it hardly ever happens in computing that you can move to a new system and see huge gains without changing the codes, but the switch from Trinity to Crossroads will do just that." Said another way, crossroads combines the magic of Riken's Fugaku supercomputer with the more familiar x86 architecture and execution environment.
