China’s first exascale supercomputer will enter service by 2020 according to the head of the school of computing at the National University of Defense Technology (NUDT).

It is, for instance, the target power of the Human Brain Project.

Exascale computing would be considered as a significant achievement in computer engineering, for it is believed to be the order of processing power of the human brain at neural level.

one exaFLOPS, or a billion billion calculations per second. Such capacity represents a thousandfold increase over the first petascale computer that came into operation in 2008

The US Department of Energy is in the process of revamping the contract for the Aurora supercomputer, shifting its deployment from 2018 to 2021, and increasing its performance from 180 petaflops to over 1 exaflop. That will more than likely make it the first supercomputer in the US to leap over the exascale hurdle. https://www.top500.org/news/retooled-aurora-supercomputer-will-be-americas-first-exascale-system/

The measure legalizes marijuana possession, home growing, and sales for adults. The federal government will oversee remaining criminal sanctions (for, say, selling to minors) and the licensing of producers, while provincial governments will manage sales, distribution, and related regulations — as such, provinces will be able to impose tougher rules, such as raising the minimum age.

What sets Canada apart, though, is it’s doing this as a country. Previously, the South American nation of Uruguay was the only one that legally allowed marijuana for recreational purposes.

Canada, like the US, is part of international drug treaties that explicitly ban legalizing marijuana. Although activists have been pushing to change these treaties for years, they have failed so far — and that means Canada will be, in effect, in violation of international law in moving to legalize.

It could also follow Uruguay, which has essentially refused to acknowledge that legalization violates the treaties. Despite warnings from the UN Office on Drugs and Crime, no one has taken significant action against Uruguay for its decision.
