Yep, Feeder went down about 09:00. Now no work units available. Back to GPUGRID for me.

I believe Folding@home can also support ATI (from what I've read on their website). See April 2008.


April 2008 We have released our second generation GPU2 code for ATI clients.

I'll try the 4850 on Collatz.

As for Folding. It would be ideal if it was anything to do with Boinc. Really! :roll: :wink:

Yup I got Collatcz working on the 4850 once I'd installed BM 6.10.0 and the optimised app. It's no substitute for MW mind. :(

End of the gold rush


"Credit Reduction
September 11, 2009
Milkyway's credit awarded has been a bit too high for awhile now, and we're bringing it down to be in line more with other projects. We've been using a credit multiplier of 7.5 per double precision FLOP and other projects are using around 5.4 per double precision FLOP. We're reducing our multipler to this, so credit should be down around 20-30%. I know everyone hates credit reductions, but it was really needed. We also have some performance improvements for CUDA and ATI applications on the way out, so hopefully it won't be too bad. As usual, try to keep the forum flaming about the credit changes somewhat civil."

Yup, but the new v0.20 ATI app should claw back a fair proportion of the loss. Due for release shortly I believe.

The danger is that he who must not be named will return once more to reduce the credit per flop multiplier.

No amount of googling has clarified Steve's meaning for me, but there you are!

Our daily total has been hit quite badly by the MW recalibration, but so too has that of our rivals so no need to panic!

I've got to say that I always thought that Milkyway ATI was over-generous and it never seemed right that my HD4850, in its ropey old E6600, was able to out-credit the whole of the rest of the farm by a silly margin.

As it is the margin has just narrowed from silly to slighty implausible so, ATI Milkyway dominated as TSBT is, we shall continue to thrive.

Yeah, I couldn't figure that one out either, apart from a word play on DA. Perhaps we just need our own Wizard to sort out he who must not be named. :lol:

Bearing in mind the googling I just ran, I also now expect a knock on the door from the FBI :roll:

Anyways, v0.20 is posted. Downloading it now. Early reports suggest a speed up over 0.19.

/Edit/

Anyone know how to persuade BT to increase the bandwidth on a rural phone exchange? I'm gonna need it now.

It's difficult to tell for sure with long and short WU's mixed up, 3 WU's running concurrently and the GPU time not matching wall time, but on two machines tested so far, it looks like about 30% speed increase :D

Post by Nightlord »

A word of caution!

I can't (yet) get the ATI v0.20 app to run under Win7. Not sure about Vista becasue I don't have an ATI enabled Vista box. I have a "can't generate output file" error when the WU starts crunching, yet it's fine with the 0.19 app on the same machine. I dropped a note in the MW forums, but as yet no further info.

The XP machines are running much faster on 0.20 than 0.19 though.

YMMV :wink:

#26

Post by Nightlord »

After much gnashing of teeth and dozens (hundreds?) of trashed WU's - boy to these GPU's crash the WU fast - I got it working on the Win7 box! :D

Upgraded to Catalyst 9.9 and the beast sprung into life. 8)

The speed up is confirmed at around 30%, which means that my three cards should now reach 11-12k - more than before the credit reduction.

Right Milkyway 0.20 and catalyst 9.9 it shall be, from tomorrow anyway!

I need some pointers on how to keep Milkyway running right now. I'm struggling to keep machines working. Everytime I walk away things break less than an hour later. Out of 10 ATI GPUs I'm guessing at any time I actually have 2-4 working....painful :?

Some machines just stall, they sit there with WU's ready to run but start none. Others show as started but the 0% completed never goes up. And finally my most stable machine historically is now my worst and I have not changed anything but the BOINC version and the ATI app. It's looking like changing everything around again. Is anyone else struggling with 6.10.3 & 6.10.4 or have the gremlins parachuted into my place ?

I don't have any machines running 6.10.x clients, but it seems there are still problems with the schedulers on them.

If you have no other projects running on those boxes, you could try rolling back to the standard client 6.6.36, or if you have other projects running, I think crunch3r has released a version of a "fixed" client in this message on the MW forums.

TBH, the boinc client release is a mess just now; ATI cards are supported, but the client is very buggy. I run my ATI cards from 6.6.36, treating them as CPU's. That frazzles the scheduler and causes problems for other projects. So I use Virtual Box on those machines to host Ubuntu 9.04 and run a completely separate instance of Boinc and crunch other projects from there.

I've got no idea how to keep MW running. All I know is:
1. First time I tried it the results were so unrewardingly irregular that I sold that rig to JockMacMad!
2. My 4850 on an E6600 (BM6.6.36) blasts along very productively and only sometimes falls over.
3. My 3850 on a Q6600 has been very prone to stopping (despite me upgrading the cooler) but has done much better since I moved to BM 6.10.4
4. GPUs seem to fail rather quicker than CPUs when running flat out under 24/365 conditions.
5. Collatzc seems to stress cards less than Milkyway (or indeed GPUGrid) and might be a better bet for an aging card that can't handle MW (or GPUGrid) anymore.

I have just got back around to crunching this project on my shiny xfx7970, but due to the cost i will be only running 48 hours at a weekend.

Had a trial run today and on a full hour i got about 12K in credit so if that's the case i will do 1/2 million so i think that's ok.

Hello again by the way, been a while.

Welcome back and yes as you have seen, when it comes to double precision projects, not much keeps up with a 7970. They are impressive beasts.

Well i have decided that the cooler on my 7970 is a great big pile of guano, its soooo noisy its doing my heed right in and it cools rubbish the card is at 79c whilst running MW@H, so i have ordered one of these > , i have modded a sapphire card with improved cooling before so i am fairly confident in doing it, will be here on Tuesday and i cant wait.

Looks good. I have a similar cooler on my 6990 but with only 2 fans.
Being double precision MW does push the card hard, but 79 c is a bit on the hot side. What fan speed does catalyst report or try afterburner to monitor what the card is running. Also is the case getting enough air pushed through it ? Could it be that the card is trying to cool itself with the hot air in the case as I have always found that the cards are not very good at pushing the air out of the case by themselves and extra fans pushing air in the front or side and out at the back make a huge difference.

I have this case > http://www.scan.co.uk/products/antec-30 ... version%29 With the 2 120 mm front fans fitted also a side fan blowing on the GPU and all are set to high atm.

Image

I am also thinking about getting a corsair H80 for the cpu but i am dithering about it, my cpu has a big ass heat sink with a 120mm fan (cant remember what it is) on it so i think its fine and all it will do is free up some space really that's why i cant decide :?:

What cpu and what temps are the cores running at? I use a H80i on a i7 3770. It's odd though, the outer fan, up against the case is quiet at max rpm, but the inner fan is noisy as heck at max rpm. Had to use the Corsair link to manually lower rpm to only 75% and it still makes a fair amount of noise. Temps stay high 60s to low 70s. BTW, had to mount mine on the rear 120mm fan port. It's the only one that would give enough clearance over the mobo, DIMMs, plugs. Also, despite what the instructions say, point the fans to blow out. That way you're not blowing hot air back in to your GPU.

I do have one of my cases that has a huge fan fitted to the side that was blowing onto the gpu and I found it caused turbulance round the gpu's ( 4 of them in this case ) and actually increased the temp. I swapped the fan round so it was sucking the hot air away from the gpu rather than blowing , especially if one of the front fans is directing air along the gpu.
You could try flipping the case onto it's side and take off the side plate. If the GPU temp drops without the side fan blowing on it, then it probably is turbulent hot air simply rolling round the gpu and swapping the direction of the fan round would hopefully make a difference. I won't insult by asking if you have checked the gpu radiator is clean :D

I have never had hydro cooling so can't comment on that but I do have all my crunchers fitted with aftermarket coolers as the the stock ones are never up to the job. Also I always get coolers so that I can direct the hot air straight towards the back and out, rather than the stock coolers which just chuck the heat onto the back of your gpu and into the psu.

@ Scole i am running a Amd fx-6200 with an Ocz Vendetta II cooler and all cores are running at between 21c at idle and 38 @ full load, when you say between high 60s and low 70s do you mean f or c?

@ Alez i turned off the front 120mm fans and reversed the side fan and my Gpu went up to 85C, when i turned them fronts back on it dropped to 82c and then i put the side one back to blowing instead of extracting and it dropped down back to 79/80c, so i think the case fans are ok, i definitely need that improved cooler for the card that i have ordered and its been dispatched and saying delivery tomorrow (Monday) ye har.

I have stopped new tasks now for the weekend and will start them again next weekend there just running down the noo, as i type i have 5 left, so in about 1 min 30 i'm done till then.

Yeah, 70c. If anyone has suggestions to keep it cooler, I'm all ears. I have another LGA 1155 CPU and it's difficult to keep cool also. Though the GPUs stay 70c or below.

I couldn't look cross at my CPU without it shooting over 50c. What are you running on the 6 CPU cores?

Sheez that cpu is hot, i'm guessing by your question your running projects on the cpu, i am not running anything on mine well just 1 core is going with MW tother 5 are doing zip because i cant be doing with all the heat when they do so i don't.

All my cpu's are always running close to 70 c. ( or above ) :D I had my first i7 running at 90 ish for months when I first started without realising and it's still going strong :shock: I believe the AMD cpu's run hotter than the intels normally and I can only dream of having mine run at 30. Short of some serious mods to cases ( or custom ) and major amounts of water cooling, I don't think you could run a core at 100% on Boinc and be below 60 - 70 c, which ( as far as I am aware ) is still well below the temperature at which you can damage a chip anyway.
My sapphire 7970 flat out and over-clocked stupidly on MW runs at about 60 - 62 c and since you have tried reversing the fan etc it does seem that the stock cooler you have just isn't up to the job. Hopefully the new one will sort the problem out for you.

Is anyone else having problems with this project????

It keeps yo yoing between 64% and 100% constantly and when it goes to 100% it slows my card down to 500mhz from a 1000mhz, i have played with the app_config file and no matter what i do it won't stop doing it, i have reset it as well, its slowing it right down and its freezing the gpu sometimes and i have to re boot the pc to make it go again :evil:.

If i can't stop it i will have to bin the project, all the rest i do run flawless its twisting my head :cry:.

I think it's caused by the power save function in certain drivers. The clocks hit max, but at max you are only pushing 50 % usage, so the power save downclocks, but when you downclock you are now pushing 100 % usage so the clocks ramp up. It seems to be a particular problem with 290's. I believe there is a fix but as I don't have one didn't pay attention.
Any hoo I had exactly the same on primegrid with my nvidias. Doesn't look pretty on the graph but worse it was causing the cooling fans to surge which couldn't be doing them any good. The solution was to run 2 units concurrently on each gpu to keep the load high.
I presume this is on Milkyway tasks. The seperation tasks are usually more stable. Which driver are you using for the cards ?

Well i was running 4 on each gpu of the 7990 the 7750 has not been put back in the system just yet.

It was running fine and all i have changed is to put a water block on the gpu but everything else runs just fine without this problem.

I have took the app_config file off and it still did it, its that 100% power save whatsit, i need to find the solution and for now i have retired the project until i can find that solution as it was annoying in the extreme.

Am using catalyst 13.12, been using that for yonks.

When you removed the config, did you 1) re-read config files 2) wait until all tasks completed that were pending before the config change. When a task starts, it makes a copy of the app configuration in a slots folder. It will use those settings. Need to wait until new tasks start to make sure new config being used, I think.

Though the only thing I can think of that might be different and make a difference is you now don't have fans plugged into the GPU. Is anything plugged into the old fan plugs? If not, could that be confusing the GPU? Even if it is, I don't have any suggestions to prevent that.

Consider trying catalyst 14.4?

Check out the comments in this acticle...http://www.techpowerup.com/195941/amd-r ... .html?cp=3

Search for "disable ULPS". It's how to disable the power save feature. Here's the gist...
The 99% usage on GPU2 is a bug caused by ULPS. ULPS is supposed to be a power saving feature for crossfire, but hasn't been working correctly for many Catalyst versions now. So, Crossfire users must disable ULPS in the registry.

How-to:
In the search field (above the Start Orb) type regedit right-click on the regedit.exe shortcut that appears -> run as admin
In Registry, on the left highlight HKEY_LOCAL_MACHINE.
Hit Ctrl+F, and in the Find field fill in: enableulps and hit Enter (or click Next) or hit F3 for next.
At Every instance of EnableUlps change the value from 1 to 0
Don't touch EnableUlps_NA
Close Registry
Reboot the PC
This is the workaround for the "99% usage on GPU2 in 3D applications (games)."- bug.
The downside is that GPU2 is no longer put to sleep mode when idle (in 2D).

I knew there was a solution somewhere :D I also believe that people report 12.8 as being the last stable cat release. The introduction of the r9 cards seems to have effected quite a few of the drivers for the Hawaii and Pitcairn cards. For 69xx cards 12.8 is the last driver that will work for standard milkyway tasks although the separation tasks will work with the newer drivers.
