Do you like Huey Lewis and The News


hardspank916

In '87, Huey released this; Fore!, their most accomplished album. I think their undisputed masterpiece is "Hip To Be Square". A song so catchy, most people probably don't listen to the lyrics. But they should, because it's not just about the pleasures of conformity and the importance of trends. It's also a personal statement about the band itself.

Some people think "compute" can be a noun. Those people are wrong and should remember the word "computation" which is still a viable word and doesn't need to be thrown into the trash can.


16yYPueES4LaZrbJLhPW

Can you explain to me the wording for "Compute Pipeline" then? Not being condescending, I'm a developer who works with graphics APIs for GPU computation, not a linguist. This wording is the only wording I've ever seen in documentation and it's always been used as a noun or a verb, never just a verb.


BujuArena

There's no good reason for it not to be "computation pipeline" or "computing pipeline" instead. That being said, there's no "pipe" in it, so "pipeline" itself doesn't make sense. A series of different computations being done on transformed data is more like a factory assembly line than a pipeline, but "pipeline" is shorter, so it's not too far off.


16yYPueES4LaZrbJLhPW

RE: Pipeline I wouldn't say the data is transformed from one to the next, they do flow without major modifications from one step to the next. Take one frame from a particle emitter with a trail for example: - Renderer prepares a texture from what is shown on the screen - Vertex Shader moves the particle around the space - Texture Shader (or Fragment Shader, depending on the API) fades the alpha value of the previous texture in the texture buffer to create a fading trail effect - Texture Shader 2 applies the vertices calculated in the Vertex Shader to the texture as opaque points to be the new head of the trail We don't typically use "[Factory](https://www.tutorialspoint.com/design_pattern/images/factory_pattern_uml_diagram.jpg)" unless it's a Class that builds another Class with some inheritance. Pipelines are a point A to point B system. EDIT: plaque -> opaque


chickensmoker

I guess it’s just an ease of use thing then? Like how people don’t tend to use big words like “elephantine” or “commodious” without very good reason when words like “big” and “huge” exist? Especially in stuff like tech where communication between a team is massively important, you want to keep as many words as simple as possible, hence we use terms like “compute pipeline” rather than the much more painful to use “computational conveyor belt”.


elikoga

Some people don't seem to work in tech I guess


highSticks

apparently the hole also consumed the title of this post, at least partially


EverythngISayIsRight

This clickbait title should have at least included the words "Simulated Image of ____". Its not a real black hole


michicago44

It is a real black hole.


Lewri

You're joking, right? This is talking about the Event Horizon Team image of Sagittarius A*, the supermassive black hole at the centre of the Milky Way, with the image made by interferometry of radio telescopes.


porterbhall

I believe the point is that creating the image consumed that much computational power. The title makes it sound like all of that computational power actually was consumed by the black hole itself.


ciaranmac17

Wait, so the real black hole consumed all those CPU cycles? It mist be way closer than the astronomers think...


EverythngISayIsRight

Yes, but the image is simulated. >To that effort, the **researchers created a simulation library of black holes** that leveraged the known physical properties of black holes, general relativity, and a number of other scientific areas. The idea was that this library could parse the enormous amount of data captured by the EHT array into an actual, viewable image


JamesIsWaffle

Doesn't anyone understand what that title means? In a language that a real person could understand


LiquidWeston

It probably took Somewhere between 1 computer spending 100 million hours computing or 100 million computers spending one hour computing to create this composite image. I could have gotten the same effect in 2 minutes with a few LED lights a dark room and a bagel


Imagine357

How do we count computers now that one computer can have many processors? Don’t we need some scientific unit of measurement here, like horsepower? That really has little to do with actual horses these days.


neoplastic_pleonasm

Supercomputerologist here. The title will refer to the number of core hours. The supercomputer is Frontera at the Texas Advanced Computing Center. Their main cluster has 8,008 nodes (computers) with 2 sockets (CPUs), each with 28 cores. So it would have taken the whole cluster about 9 days to calculate. But cores can vary in capability, so the supercomputer equivalent of horsepower is FLOPS, floating point (arithmetic) operations per second. Their cluster is around 25 petaflops. For comparison my desktop will do a few hundred gigaflops and [email protected], the (soon to be) most powerful supercomputer in the world, will do about 1.5 exaflops.


haslowlo

An intelligent answer on Reddit!?


CoderDevo

Plus, they read the article: > The vast majority of the required computing hours - around 80 million - were run on TACC’s Frontera system, a 23.5 petaflops, CentOS Linux 7-based Dell system currently ranking 13th on supercomputing's Top500 list. Frontera leverages 448,448 CPU cores courtesy of 16,016 units of Intel's Xeon Platinum 8280 chips, a Broadwell-class CPU leveraging 28 Intel cores running at 2.7GHz.

Not how it works It's like saying a highway spins at 1.2 billion RPM because of how many engines are on it It doesn't tell you how much power is available or anything at all really GHz is no longer an indication of processing power. Processing power can only be measured by making it do work


CoderDevo

This system has as a calculated peak performance of 38,745.9 Teraflops = **38,745,900,000,000,000** floating point operations per second. The fastest existing computer is in Japan and is calculated to perform at 537,212.0 Teraflops.


orangutanDOTorg

Great Scott!


CoderDevo

Subtract 5-10% for multiprocessor message passing and remote direct memory access, since the motherboard interconnects are not as fast as direct memory access. That said, they are connecting the motherboards using Mellanox InfiniBand HDR, which can transmit data at 20 GB/s.

Suck it, Trebek


gtavo

Something is not adding up from the numbers in the title alone if you want to shed some light. 11,425 years = 99,995,400 hours I assume this time metric is for a single computational core doing the full calculation. Divide the core hours by the wallclock time to get the number of cores. But 100MM core hours divided by 99995400 hours gives 1.000046002116097 cores, which is not that impressive. What am I doing wrong? Edit: grammar


neoplastic_pleonasm

11,415 years = 4,166,475 days 8,008 nodes * 2 sockets * 28 cores = 448,448 cores 4,166,475 days / 448,448 cores = 9.3 days / core


wilted_ligament

If you're trying to get the number of cores that were used, you would need to divide out the walltime, which you don't have. You used 11,000 years as the walltime, which is what the article says the walltime would have been if you were doing the computation with a single core. So, of course, when you divide the total CPU-hours by that number, you get 1. That's what CPU-hr is.


zazzyeinestein

Thanks man!


Status-Table8498

Supercomputerologist sounds really cool


Reset_Assured

To add to the other comment, the reason it is CPU hours is because a core can only do one thing at a time. So you are paying for the time to use that core. Prices can be higher depending on the type of core that is being rented. There are only a few super computers in the world and researches have to rent time, or at least schedule time on the machines, and they bill on the combined time that each core used.


muckduck99

I’ve worked with a supercomputer processing a large workload one time. The unit of measurement is core hours. So if you have a 6 core processor that’s utilizing all cores to process whatever you’re doing and it takes 2 hours to finish the job, that means you used 12 core hours


issius

Well… CPU hours would be the unit of measurement lol


dm80x86

But without a standard for what a CPU can calculate in an hour it's meaningless. I had a Mac SE that took an hour to load a JPEG.


Pangolinbot

Supercomputers are typically measured in FLOPs (floating point operations per second) basically any math operation like addition or subtraction, multiplication or division. Right now the best supercomputers are measured in the hundreds of thousands of teraflops while an Xbox series X can manage 12, allegedly. To your point cpu hours is a meaningless term, but I chalk that up as more of a science journalism failure than anything else. They probably just reported the number of cores that were rented by the hour on a particular supercomputer


CoderDevo

cpu hour is how scientific efforts are charged for resource consumption. They must request and be approved for a research grant equal to or greater than the cost of resources required to complete their work. Source: former supercompter admin.


NoRace5075

Just lookup a benchmark for the processor used and run with that. Precision doesn't matter here since you're rounding to the nearest order of magnitude anyways.


a_saddler

>I could have gotten the same effect in 2 minutes with a few LED lights a dark room and a bagel I would love to see you try and capture and image of said bagel if it was on the moon, because that's the size of that black hole as it appears on our sky.

The remainder 20 million simulation hours were computed on the NSF's open Science Grid, which leverages unused CPU cycles in a distributed computing fashion to unlock compute capabilities without the need to deploy costly supercomputers and related infrastructure.

o0flatCircle0o

We can’t take a picture of a black hole with one telescope, our stuff isn’t sensitive enough and they are too far away. The only way to do it is to point a bunch of telescopes at it over a long time, coordinated around the world as it spins. The data those telescopes capture is immense. So that data needs to be crunched by super computers in order to turn it into an image. If one computer worked on it alone it would take 11415 years.


acebush1

Ok so **creating a composite image of a black hole consumed 100 million CPU hours.** A black hole did not consume any CPU hours because that obviously makes no sense.


AgITGuy

So it used a supercomputer to process this whereas your laptop would be chugging away for millennia to try to get to the end. The laptop would likely die of old age before getting anywhere near done with a portion of the work.


[deleted]

It means \[apparently\] the image took around 200 real hours to compute. It's called journalism. Ofc, those hours spent do not speak to the accuracy of the derived image. For that matter ofc, it's possible this reply is as misleading as the title.

CRE_Energy

Honest question: Is there confidence this is actually what it looks like? Or did they write a complex algorithm with their assumption on what it should look like, input a bunch of "space noise", and the program returned an image that met their initial parameters (assumptions)? I don't mean to be too cynical. I just don't understand where this falls on the spectrum from "Wow this is ground breaking stuff" to "garbage in, garbage out".


DrTenochtitlan

On a scale of garbage to groundbreaking stuff, this is in the "will be remembered as one of the most scientifically important photos of the twenty-first century" category. Basically, they were able to take a bunch of telescopes from points all over the Earth, from Hawaii to Europe to the South Pole, and tie them together. By using the slightly different positions from all over the planet, a computer was basically able to simulate a telescope with a mirror size of the entire Earth, and use that to fill in the gaps in the information. It's absolutely a real image made up of data sets from multiple telescopes. When you're looking at something that far away though, there's going to be a lot of static. The computer is able to take the slightly different positions and figure out how much is black hole, and how much is static by comparing the images.


ListenLady58

Your answer is the clearest for me. Thank you!


extramental

Veritasium on YouTube has a cool video on it.

Thank you for the explanation! I got stuck on the part about creation of the simulation library, which made me think "they told it what image to create, so shocking result, it created the image they asked for".
