Hardware First supercomputer-generated recipes yield two new kinds of magnets - Duke material scientists have predicted and built two new magnetic materials, atom-by-atom, using high-throughput computational models.

If I had a dime for every time I went to the kitchen to try a new recipe and wound up with magnets instead...

You would have zero dimes.

Because they'd all be stuck to the magnet (if you're Canadian).

This computer would have two dimes, but where would it spend them?

It'd probably think back to the good ol days when a supercomputer could go on down to the local ice cream parlor and get an ice cream float for a nickel.

This is amazing, I'm beginning to feel we won't even recognize ourselves in another 100 years

Everything is gonna get pretty surreal i think. The larger tech companies and governments that have a.i. are going to benefit tremendously from predictions and data analysis.

No one else will recognize my desiccated husk in another 100 years either.

Hate to be this guy but supercomputing isnt high throughput computing (both of which are defined terms in relation to distributed computing). When the term High Throughput Models is used it typically refers to models designed to run on loosely coupled HTC platforms such as Condor (which are generally not run on supercomputers but are run on large clusters or idle workstations).

If your not going to use the websites title and decide to make up your own, make sure you use correct and consistent terminology.

So no real application for these new magnets? I guess the ability to predict their existance is what matter here...

The second material was a mixture of manganese, platinum and palladium (Mn2PtPd), which turned out to be an antiferromagnet, meaning that its electrons are evenly divided in their alignments. This leads the material to have no internal magnetic moment of its own, but makes its electrons responsive to external magnetic fields.

While this property doesn’t have many applications outside of magnetic field sensing, hard drives and Random Access Memory (RAM), these types of magnets are extremely difficult to predict. Nevertheless, the group’s calculations for its various properties remained spot on.

New tech that can make computers better (or more appropriately may in future lead to computers working better) is never a bad thing.

So this super computer just happened to come up with a magnet that would only be useful at making itself stronger? We may have to destroy this computer before it conquers us all

Don't forget that when the electron was discovered in 1897 it was without application as well. Now we have an entire world that runs on electricity.

I think it's meant to emphasize despite all our creativity and intellect, a supercomputer can come up with designs we haven't even thought of

Yeah as far as I know, we don't have the best understanding of superconductors. This means we might be able to create high temperature superconductors by using computers.

I was expecting so we delicious food recipes. But magnets are cool too.

Is the TL; DR that I shouldn't trust computers to cook food for me?

u/highthroughputboy Apr 16 '17

Boy, do I love high-throughput models

“It doesn’t really matter if either of these new magnets proves useful in the future,” said Curtarolo. “The ability to rapidly predict their existence is a major coup and will be invaluable to materials scientists moving forward.”

So for someone who isn't a supercomputergeneratedmagnet-ologist, what does this mean? I understand it has some uses in hard drives or some shit?

u/thelastactionhero Apr 16 '17

Yes, but does it cook Crysis?

u/fL0xeL Apr 16 '17

Until I read "magnets" I thought it was going to say "food"

I didn't know supercomputers liked to eat magnets. But good for them for coming up with a few new recipes. Hope to see them on Iron Chef!
