OpenCL for CPU Scales Applications Easily on Four Six-Core AMD Opteron Processors

[rickiricki999]

Hello, can I ask you, is this CUDA open CL system avaiable to count CFD computation of fluid dynamics?? could you please write me ate richard.pinka@gmail.com ?, thank you

[doug65536]

Why wouldn't you have a repeatable scenario to show a true comparison? And show some actual numbers?

[Lixts145]

name "game" is - The Powder TOY - ;)

[Crysis2isOnline]

Wish they'd hurry up and tell us how the hell we're meant to get openCL to work in TPT! Fed up of having an 8 threaded i7 and still lagging on big sims.

[YaBaDji]

Nvidia is way ahead in gpgpu computing :(

[Zwank36]

sadly amd decided to beat a dead horse with a stick (x86). WHY AMD WHY! CSIC does not scale for NUMA environments!

[Zorobyte]

My question is, where can I download the OpenCL enabled Powder Toy?

[worldsking3]

It didn't scale proportionately from 18 cores to 24 cores. At 18, it was 5.26 ms and at 24 its 4.08 ms. Moral is to stop at 18 cores!!!

[antzrhere]

@worldsking3 That's 96.7% scaling efficiency - I would say that's as proportional as your ever going to get.

[antzrhere]

@worldsking3 Furthermore, if you were to be picky you could argue the "lost" 3% is down the fact that this isn't a controlled comparison - the user is changing the scene conditions with the mouse so it won't be a 100% fair comparison between the two scaling setups...

[nattsurfaren]

It would be interesting to know how much opentk can use of what is presented in this video.

[stigyo92]

simple 24x1=24 times :p

i want that build for gaming xD

[WikkuPL]

Wow. Small, little known game and used by big company like AMD.

[zc00gii]

I've developed on that game. The Powder Toy.

[Sirrom5]

1 core vs 24 core and what benchmark is this? is ti for opncl or for more cores?

[JetJL]

so how fast could it run Folding @ home? My gpu can do it in 4 hours how fast can this do it?

[cyborgtroy]

@JetJL - Probably slower because it uses the CPU.

[Consumerofknowledge]

When are we gonna see something that will never slow down? How about a 12 CPU socket motherboard? WHy the hell isn't this possible yet, whats the excuse? I must be dreaming.........

[trecool9992]

@Consumerofknowledge The excuse is that you're not paying enough,

Go get the most expensive Mac I could make on Apple's website (£32,000). That should do it.

[mikeccuk2006]

they all have tiny tiny coolers :(

[aronjakob1]

give it to me, ive got 112 cores at 1,5 GHZ: my GPU

[SRNF]

how can anyone afford 24 lol

[PowerMaxSite]

yeah u can buy instead 16 core for bargain price at newegg

mobo tyan 300usd (4 cpus)- newegg

4 cpu's quad cores 800-1000usd -newegg or ebay

2x8gb ram - 400 usd -newegg or ebay

1200W thermaltake PFC 100usd -newegg or ebay

case for "Servers" 100-200usd -newegg or ebay

2x2tb drives 400usd -newegg or ebay

nvidia tesla for rendering (or not if u dont need) - 300usd + some ati high end 5 series card or something

and a madafakin triple lcd's - 500 usd

and u got pc for the price;)

[trecool9992]

@SRNF By being the company that makes them. Lol...

[luigiman83]

Wish I had the OpenCL version of powder toy... My other 7 cores are bored out of their minds!

[cyther39]

GPUs are really powerful!!

wer can i download this software??

[Smoochboy]

First: Its property of AMD/Ati, so you have to ask them, but i think they won't gave it to you.

Second: "OpenCL for CPU Scales Applications" is in the Topic. AMD released a kind of OpenCL Driver for the CPU, not for the GPU. The GPU Driver ist not finished yet, but you can try it in the latest ATI Stream SDK

[Electrickbreadstick]

How much processing power and resources is lost by running it in this setup as compared to theoretically compiling the total available resources and calculating the response time?

how much power is lost in the process of a setup like this?

Imagine you are that first core in the one core test.

Now imagine you are that same core but in the 24 core test, are you contributing the same amount?

[wildchildplasma]

I'm looking at building a system with 48 cores and 500 Gigs of ram using the SAS as it was meant to be used with my SSD hard drives working at a GIG/s off the PCi express bus. Possible yes. Why because I need a Real mans Calculator.

[themassau]

@wildchildplasma don't you want some nice images on your real men calculator maybe a x16 a hd 5970

[wildchildplasma]

I might build a rendering machine for the purpose later.

[themassau]

@wildchildplasma but you need live rendering :p

[wildchildplasma]

The kind of multi-deck architecture needed for real time exploration of such high degrees of computing complexity is not yet fully available and no way near my price range for now all I can do is heavy calculations and no real time rendering .

[themassau]

@wildchildplasma that sucks :( but i meaned a quad crossfire x but we will come on those technolegies soon enough or at least i think so

[KingSamLopez]

Would 24 single core cpus be faster than 4 six core cpus :)

[bastec666]

no, why do you think we moved to duel core instead of systems with more than 1 cpu? by having it literally right next to each other (the cores) it allows for faster data manipulation, hence why the new 6 core opteron is so amazing.

[wildchildplasma]

Thats a tricky Question, The simplest answer to that is that on the die the connections between the core can connect to each other faster but they would all have to share the same Ram per CPU where As with Individual cores you could connect quite fast and could have more ram per and faster ram access per core.

So It all really depends on needed use and setup.

[benjojo12]

Depends on how the app you are using is programmed.

[pokerface3699]

no one uses 1 core anymore, they should compare it to 2 or 4 cores

[sacredgeometry]

they still manufacture 1 core cpus and sell them....and i think you will find that 90% of computers if not more in use are still single core.

[wayzey]

No, it's more like 30% are 1 core, 60% dual and 10% other.

Though of course the majority of other would be 4 cores.

I have a quad core computer and most my mates and people I know have dual core. The school I go to and just public computers in general are all 1 core though the computers usually struggle to play mindsweeper.

[sacredgeometry]

i think you are vastly underestimating things. Most computers are in offices and schools these computers are used for basic tasks like spreadsheets and general office reasons.....they dont need updating and probably havent been completely or at all.

granted most home users would be running multiple cores but home users arent the bulk of the market.

i stand by my original assessment.

[themassau]

@sacredgeometry i only know one guy that has a single core and it is a verry old pc like 7 years old

[sacredgeometry]

well you and your friends are representative of most of the world neither am i to be honest but at-least i'm not struggling with the notion

most people in the world are running windows xp on computers pre multicore with 1280x1024 res monitors or less. sorry but thats the truth even if might not and you might not ....if you need a reason here it is half of the world owns 1% of the wealth in this world.

peace

[PowerMaxSite]

@sacredgeometry i live in Poland, and i had and 7year old pc for hmm 3500pln(1000usd) and i had with it ->main pc(512ram,9200se,80gb hdd,celeron 2.8ghz),router,printer,2x dvds,windows xp he original,and samsung 793df lcd with fakin 1280x1024,...

u have to live in africa or something XD

anyway stop saying shits about statistic... if u were going to study "statistics" 8h/24 then at home 5-10h u will definitiely stop saying about madafakin "statistics,in statistics"...

[sacredgeometry]

Um, sorry what? Sorry i couldn't decipher that.

Peace

[sacredgeometry]

24cores? where in the hell are my consumer grade 24 core cpus? (i know some of those are probably gpu's) but damnit i want it now.

once again capitalism slows down the technological advancement of our species and for that i award you one darwin point (to be cashed in at the darwin awards 2010)

[MattxBuddyxMatt]

It's not actually a 24 core chip. Its 4 6-Core Opteron Chips. 4 Chips X 6 Cores per chip = 24 Cores

[m3rc1l3ss]

If you listened to the end of the video, you would realize that this is not meant, at least currently for consumer computers.

[sacredgeometry]

? if you read my post i said "why isnt it"

[TRAyres]

Graphics cards have hundreds of cores (although they are not the same as CPU cores - yet). The average nvidia graphics card has 192 cores, if I recall correctly. Basic desktops today have 2 or 4 cores - but these are more complex and general than GPU cores. GPU cores are becoming more general (see GPGPU).

Capitalism is what has allowed all of these things to even be developed. Your computer is a masterpiece of capitalism, and your misunderstanding of this is truly immense.

[sacredgeometry]

no my computer is a result of human ingenuity your understanding of economics is very very narrow if you think the world in its present state needs a monitory system at all, we are too advanced for the antiquated model of economy our world uses, thats without accessing the fact that the way it works is a disgusting inefficient waste of resources.

the computer like all inventions where born of necessity, we needed a way to make sophisticated computations

[roars25]

Hey Sacred, Infrequently does one find oneself reading the comment's as the majority are often misguided and no real valid points so to speak. I just wanted to express that I also share your consensus on the monetary system and that it s a draconian system even that must be abolished sooner rather than later because it is paralysing the continued evolution of the human race.I just wanted to convey you are not alone in your thoughts and so many people share the same consensus around the world :)

[sacredgeometry]

thank you, the is a incredibly reassuring.

[mmstick]

Lol, someone doesn't read titles. xD

[MasterDOOM2010]

AMD - ATI Radeon Best Choice muhahhah

[gigabit942007]

play gta iv on that thing !!

[romale007]

xD i LOVE AMD

[magick1969]

None of you geniuses has a clue how useful this will be and is on demoed GPGPUs. OpenCL doesn't care whether it's a CPU, a GPU, a dedicated DSP or what not.

[xelink]

you're ignorant.

AMD is kicking nVidia ass, last time I checked their GPUs were HALF THE DIESIZE of nvidias while offering nearly the same level of performance and their architecture scales better with mulitple GPUs(tri 4890s is the fastest setup on the market)

yes, they have more shaders... but the shaders are much smaller and simpler. If anything NVIDIA needs to be more innovative, their GPUs are basically the same as they were in 2006 outside of a few tweaks. while AMDs have evolved.

[themassau]

@Mr937595 but still they are more powerfull and have better gpu i mean wtf they even give better price/preformance why should i buy an nvidia

[Mr937595]

they are more powerful for the time being. got myself a 5870, love it.

[ps3universal]

GPGPU's suck and have no purpose in the world let the CPU do the GP of the GPU and let the GPU be a GPU not a GPGPU

[j3llyf1sh]

Will it blend?

[SterkeJoep4]

24 cores? AWESOME

GO AMD!

[MachineMezziah]

Amazing what technology is capable of nowadays.

[thelasthallow]

will it run crysis?

[pearlsea]

Will it play pong?

[staticxmako]

crysis=max 4

[thelasthallow]

no shit. crysis only uses up to 4 threads.

ok then Will it run GTA IV?

[mozart116]

It would probably murder crysis
