Right, but then you have the questions of 1) why do leptons have (a multiple of) the same fundamental unit as quarks, and 2) why does that multiple equal the number of quarks in a baryon, so that protons have a charge of exactly the same magnitude as electrons?
I mean, I guess you could say that charge comes from (or is) the coupling of the quark/lepton field to the electromagnetic field, and therefore if it's something that's quantized on the electromagnetic side of that, then quarks and leptons would have the same scale. I'm not sure that's the real answer, much less that it's proven. (But it might be - it's a long time since my physics degree...)
Lots of other versions exist including reputable ones like Intel’s MKL. The hard part isn’t reimplementing it, it’s validating the output across a massive corpus of scientific work.
BLAS is an example though, it’s the tip of an iceberg.
Argh, we first ignored the fact that most of its income comes from being the lead e-commerce retailer to just focus on AWS and then we need to discount the fact that the majority of AWS is CapEx towards hardware / datacenter (expected CapEx this coming year is $200B), to just leave the software. Whatever.
One thing is for sure: if the seal builds and manages hundreds of billions of dollars worth of computer infrastructure across seven continents, it isn’t just a software company.
