I do hope that they are checking the results to make sure that they are crunched correctly so they don't end up with a bummer like the cuda 2.1 and earlier compiled stuff. :-(

[Digital Parasite]

That is a nice keyrate!!! :thumbs:


Now if only there were more ATI supported projects that were actually doing something useful. :( Hopefully if OpenCL picks up popularity, it will just work for everything out there.

[Brucifer]

Oh I think that will happen. Afterall, the stream thing is just getting going. I was reading on another project page (boinc one) can't remember which one, but one of the prog/admins was commenting that it was taking them much longer than they had originally thought it would to get both the cuda and the stream clients going. He intimated that there were some differences between them that created difficulties. So if it is hitting one place, it's likely hitting others as well.

I went and bought a HD 4650 to experiment with. I wanted one of the 48xx but the local store was out of them. And I'm running it on XP Pro, and there's pluses and minuses. Overall though I'm impressed with it. For one, it doesn't need the PCI Express electrical plug, just takes it's power from the m/b, so it can't be sucking too heavy a draw. It also isn't putting out much heat. And it's very quiet. It's crunching a single work unit every 24 seconds, a little bit slower than a cuda 9800GTX+ I have. The cuda one puts out more heat, makes noticeably more noise and requires the PCI Express electrical plug from the P/S. Of course the heat equates to more juice being sucked down. The stream worked the first try too, which is always a plus :D

I haven't tried playing with it under linux yet. Don't know if I will really. While I'm not a windows fan at all, it is definitely much easier to get video drivers and all changed around under windows than linux. And that becomes a bit of an issue when there are relatively frequent beta changes that require changes due to new libraries and all.

I was reading that the HD 48xx put out a lot of heat, but then so do the nvida 260's and 280's and up. So I intend to pick up a 48xx stream card and give that a run and see how it goes. But so far I think that the ATI/AMD stream is going to pan out just fine on rc5 anyway. :thumbs:

[Bok]

They've just announced that they should have the ATI integration into the BOINC 6.10.x stream within a month, it's basically the major thing they are working on now that the gridrepublic/facebook 6.8.x version is out the door..

Of course you can always try MilkyWay or Collatz Conjecture right now :)

[alpha]

That is a nice keyrate!!! :thumbs:

I do hope that they are checking the results to make sure that they are crunched correctly so they don't end up with a bummer like the cuda 2.1 and earlier compiled stuff. :-(

Indeed! A 4870 can be had for £70-80 here at the moment. To get a similar keyrate from nVidia hardware would set you back a fair bit more as far as I can see.

Also, a 4650 costs about half as much as a 4870. Brucifer, you said yours is doing one block per 24 seconds. I'm not sure what size blocks those are, but if it's 2^32 keys, that works out to around 180 Mkeys/sec. Does that sound about right? If so, that's quite a big leap between the two cards..

[Brucifer]

The 4650 gives roughly 174,900,000 keys/sec on the - bench for core 0 which is the correct default core. Here the 4650 is currently running at $119 US. So yes, there is a HUGE leap between the 4870 and the 4650. So for less than double the price you get 3.3 times the keyrate which is one heck of a deal. :D

edit: My BFG GTX 260 is getting 234,310,064 keys/sec on core #6, cuda 2.2 client, so the 4870 is better than 2 times the keyrate of the BFG GTX 260. So unless there is a similar error in the crunched results from the stream client like there was with the cuda 2.1 and below clients, the 4870 is definitely a hot number on rc5!!!

[Brucifer]

Yeah.... I'm afraid that there's gonna be a lot of places "out of stock" as far as that ATI card goes. Just absolutely can't beat it for the price.

[alpha]

By my calculations, if the RC5-72 project was started from scratch using 10,000 HD 4870 cards, the keyspace would be exhausted in ~25 years. That smashes a rough estimate of 1,040 years at the current average rate.

Bear in mind that 10,000 is only 1/8th of the total number of participants.

I want one of these bad boys. :)

Wow, I actually have something that beats everyone else's gear? :guntotin:

It looks like MilkyWay and Collatz Conjecture for ATI you need to do some hacking to get stuff working properly. I'm assuming that this should sort itself out when the BOINC support ATI release is complete? I might just wait for that, not much time to mess around right now.

Me thinks that these Stream gpu's are really going to be taking RC5 by storm! :D

Keep us posted on heating/cooling on that puppy!

[IronBits]

It feels like it runs cooler than the GTX 275, 280 and 285.

[Mustard]

yeah... I was reading a bunch of the "reviews on Best Buy, etc., and people were commenting on the streams running hot. Evidently they haven't run the GTX stuff, cause to me they seem like they run warmer than the stream stuff.

What I am noticing though is that since the stream is the first public beta release that the client is not as polished as the cuda client IRT using the cruncher and web surfing at the same time. This one I'm using isn't a high end one but it is comparable to the 9800GTX+ but it's more choppy than the 9800GTX. The 4800 series are better, but still have slower screen response than the GTX 2xx geforce stuff. I imagine that will improve as time goes by. Didn't buy the stuff for surfing though rather it was primarily for crunching.

[IronBits]

The ATI card is dedicated to crunching.
I use a GTX 295 for gaming and browsing purposes. :D

To revise my earlier stat, if the project started from zero with only 10,000 HD 4890s running and nothing else, the keyspace would be exhausted in ~22 years! It just isn't cost effective to run RC5-72 on any CPU any more.

[IronBits]

For PSUs without two six-pin plugs, can a molex->6-pin adaptor be used for connecting to one of these cards?

[IronBits]

Yes, they make adapters where you can take two 5pin hdd type connectors to make a 6pin rectangle.

[IronBits]

I'm having trouble with a decision of which is better, perhaps you can help me?
2 4770s vs 1 4890
2 4770s vs 2 4850s
2 4850s vs 4890
2 4890s and be done with it already ;)

Is core clock more important than memory clock? - for crunching only
I assume we don't enable cross-fire, so the clients would see two GPUs.

Power consumption and performance as a dedicated RC5 or F@H cruncher only - no gaming considerations

Good review that covers some of the angles...

How about a blow by blow write up on how you did it, like what all hardware is involved, etc. Curious about it as I'm noticing that performance for all cards sorta sucks on screen updates when crunching hard too. I thought about just doing a system for my surfing, etc., but unfortunately I seem to have a problem with a system sitting around the house that isn't crunching. :idea:

So the next best thing is to get one set up for both. However I first need to look at motherboards with multiple PCIE slots so I can run more than one gpu. Of course I guess and option would be to get one of the healthy nvida cuda motherboards and then go from there. :D

[IronBits]

I have several computers, not in cases, sitting on shelves, configured the way I want them, for dedicated crunching only.
All hooked up to a 8 port KVM switch and 23" widescreen monitor for setups and tweakage of BIOS, accessed remotely using Real VNC.
The're referred to as headless boxen. ;)

I have ONE computer, with all the latest and greatest bells and whistles, parts and pieces, case and all,
with a 30" Apple Cinema Display, for my personal pleasure, that I may or may not use for crunching.

Somehow my crunchers end up being just like my personal computer, sans case and monitor. :)

[Mustard]

Naw, he did it because of the female shoe syndrom... they can have a closet full of shoes, but as that saying went by some gal somewhere, "If the shoe fits, buy it" so goes IB with "If a PCI-E slot is empty, fill it!" Obviously he had an empty slot. :thumbs:

[IronBits]

LOL, actually, after you posted your numbers, I was so impressed, I became curious as to what the top of the line card could do ...
Then, found out there was an OC version, so I'll let you know how well that one works to, in a few days. :D
nVidia cards will be turned off and retired for now, except my gaming card of course.

However, now that you mention it... :p ;)

Oh, and I have to stay ahead of Mustard don't you know! :D :D

[IronBits]

I like to keep an eye on things for rc5 here to:
http://teamstats.macnn.com/rc572/stats.php?page=a2&TID=26268&sort=StatsWeek

I'm almost at the level that 10 PS3s and a Mac Mini could do. :)

[Mustard]

well you don't have to worry about staying ahead of me as I've got a few too many things on my plate at the moment to be able to run out and rpelace everything with super hot running streams..... :-) Not that the thought hasn't hit my little head..... What's got my eye are those really high end cards, like the thousand and couple thousand dollar ones..... maybe for christmas.... LOL

edit: But yup, I can definitely see that the stream cards are going to walk all over the cuda stuff unless nvida makes a bit of a jump to get ahead in the game again.

edit: edit: And what's going to happen with the new PS3's? It's looking like they will be a tougher nut to crack, not that that stops anyone. The main thing they have is low power consumption in comparison.

[IronBits]

Well, not sure about that...
The PS3 does about 1/2 the performance, 3000 blocks per day for 114 watts.
vs ~250 watts on the video cards for 6000 blocks per day?
Fairly close... and I'm sure there is some tuning to do on this Stream stuff.
Plus, the PS3 is $300 and a ATI OC video card is $225 right now and I'm sure that price will come down over the next several months, as they always do.
At least it's interesting! I'm tired of the basic same old CPU, just more of them, with not much of a Hz increase... It's like CPUs stalled out.
I expected 10GHz by now, sheesh. ;)

[alpha]

Well, not sure about that...

Your HD 4890 at 680.0 Mkeys/sec should be doing ~13,400 stats units per day.

[IronBits]

Oh ya, 6000 per day is what I get with the nVidia cards. duh

[alpha]

It would be interesting if we could get some performance comparison numbers between Windows and Linux on the same hardware. Any takers? :)

Looking at the official stats (http://stats.distributed.net/misc/platformlist.php?project_id=8&view=tco), the Linux Stream client has already completed twice as many blocks as the Windows version. I'm not saying there's anything to read in to about that, but perhaps the Linux client has an edge?

[Mustard]

The linux stream was the first one worked on and released. The windows one was just released. Keep watching and the windows stream will pass the linux one, just like what happened with the cuda stuff. As for the cuda, there wasn't any diff really between the linux and windows so I wouldn't expect any real difference with stream. My understanding is that the card output is the same between 64 and 32, so distributed.net just releases 32 bit cuda/stream clients. However, like many things in life I find out, I just possibly could be extremely wrong on this. LOL

[alpha]

Ah, OK.

I've got a 4870 coming this week so I'll hopefully be posting my numbers too.

I only have the two cards running.
I turned off everything else to save money on electricity.

Looks like you bought your ATI cards a tad bit early. Double the FLOPS with the new gen card and some other goodies: http://www.anandtech.com/video/showdoc.aspx?i=3635

That's always seems to happen to me. I might get one, might not.
Double FLOPS is always a fantastic leap :)

yup, as you say IB it's a fantastic leap, but it's just a continuation of the game that's been going on that is basically designed just to separate you and your wallet from as much as possible. And like you mentioned above, some of us have been playing this game for quite some time. And sorry to say, I'm growing a bit weary of it as the old excitement just isn't there anymore. I too have put a small fortune into this game and have already retired. So I think I'll most likely just take a pass on the new stuff and the new prices, etc., etc., and just join the bystanders.

[IronBits]

Understood.
That new card has twice the processors, prolly the reason it's twice as fast ;)

funny how they don't mention anything regarding the price. :rolleyes:

So, does anyone have an HD 5xxx series GPU yet?

I'd love to see RC5-72 benchmarks of the:

5850 (1440 stream cores, 725 MHz)
5870 (1600 stream cores, 850 MHz)
5970 (3200 stream cores, 725 MHz)

This looks promising for the future:

5990 (3840 stream cores, 850 MHz)


So it seems whatever keyrate the 5870 gets, we can roughly multiply it by 2.4 to get the potential keyrate of the 5990. :eek:

[matrix_fan]

did they remove all of the stream clients permanently?

[the-mk]

there is one Stream client in the prerelease download area for x86 linux...
there are also a lot of new versions: 516... maybe it is working out the next few days, so we are able to download some new prereleases ;)

The Windows Stream client had expired before they removed the download link, so I'd guess another beta or release candidate is on the way.

[the-mk]

now there are Stream clients for Windows in the prerelease area - needs just some time to work out ;) :D
:cheers:

MrJackson2000 @ Ars has posted RC5-72 benchmarks (http://arstechnica.com/civis/viewtopic.php?p=19780660#p19780660) for his 5870.

1900 Mkeys/sec. :eek::eek::eek:

That means, with 10,000 of those cards you could exhaust the entire keyspace within 8 years.

Wow, that is fast. The scary thing is with 10,000 of those cards it would *still* take 8 years to exaust the entire keyspace... :cry:
