Am almost there from the airport but first my Uber will have to cut through downtown to avoid traffic… as for below indeed the definition for Post-K is up to 100x K; expected mean should be about 50x K. Hopefully we can release the actual numbers RSN. https://t.co/pMs8LTsyLi— Satoshi Matsuoka (@ProfMatsuoka) March 5, 2019

“…the exact day I send out an email containing a little piece of IBM
supercomputer NOC router to semiconductor job recruiter in United States…”
Is this piece of “IBM supercomputer NOC router” you emailed your property or the property of your previous employer? If it’s not your property, did you acquire legal permission from the owner to allow you to email it to random people on the internet?
Performance per watt all in, is a big design constraint/motivator for exaflop designs. ARM is amongst the best in flops/watt directly, plus the waste heat is also low per flop. Combined with feature size of the manufacturing node selected for producing this custom run of chips also improving power consumption and waste heat, ARM looks quite good compared to x86 stuff. Other stuff like datacenter/rack design reducing cooling requirements also improved power consumption.
Intel is still trying with x86, trying to get down to 10nm and beyond, and higher temperature tolerance allowing less cooling or even free air cooling (fan only, no chiller). They have demos of racks in a tent sitting in the desert. But, their vector stuff has some issues. Even proper hardware AVX512 without cheating incurs a substantial clock penalty currently.
I’m going to resist the temptation to joke and be serious here.
Nobody is monitoring your email to decide what news stories to publish. This isn’t a thing that happens.
This is, with the greatest sincerity, something that happens in your mind.
This is literally textbook paranoia.
You need to see someone about this. It is a medical problem that can be treated.
Little wondering why the exact day I send out an email containing a little piece of IBM supercomputer NOC router to semiconductor job recruiter in United States so they won’t pretend I’m unqualified for employment so they can hire an Indian guy instead…that this exact same type of semiconductor design shows up on this website as a news article… all is corrupt… US is going to crap from inside because we can’t even trust the people who find Americans jobs… and they can spy on every cloud connection we have to gain advantage over the local population…they are all spying and hiding jobs and misdirect Americans and hire foreigners instead… we have some type of Asian. Centric spying police centrally planning who gets a tech job in the US and to what degree and so matter what you do they don’t care…
Surprisingly low speced hardware on a component level.
They must have some serious innovations regarding parallelism up their sleeves.
