21) Message boards : Number crunching : ATI generate some invalids and nVidia not (Message 57140)

Post:
The drivers I had in September (before the update to opencl) didn't had the opencl feature so they won't work. That was the reason I updated the drivers from ATI.

At Seti forums I've read, that the current ATI drivers have some issues with OpenCL. Not sure if that applies here, but the latest version they recommended there is 12.8. Maybe you could try these.

Aha, nice to read that some issues with ATI are possible (likely).
Indeed the 12.8 drivers were good, I had them until a few day ago when I updated to the latest in the hope to get better results. But thanks anyway.

Thanks for the input.

The system is clean and free of dust I regularly use a compressor and vacuum cleaner for all the pc's but not a lot of dust.
And nothing is overclocked, for me the systems are too expensive to fiddle with that and cause overheating.
I lost a nVidia card that had run for 4 years (24/7) under not overclocked conditions. I guess when overclocking the lifespan will be shorter.

Also I must say that I have looked even more closely to my wing(wo)man, and some of them had also invalids with nVidia, but I still none ;-).

Running an ATI Radeon HD 5850 (cat 12.1) I just checked my application details:
Consecutive valid tasks 15020
for
milkyway_separation 1.02 Windows x86 double OpenCL


Amazing!

I got 1500 to 1700 until September.

Now I have only 3...

I did the latest update from ATI drivers, have now done 304 WU's , 145 valid and 23 invalid, 136 pending.

Einstein and Milkyway on the ATI gives quite amount of invalids, Milkyway way more though.

Than something is wrong with your GPU (or eventually something else in that system), even the old CAL app I have to use for my HD3850 does not have such high error/invalid rates as you reported in your first post (and it has a known bug where sometimes the output is not written to the std_err). The new OpenCL apps are known to run more or less without any noteworthy issues.


Yes Link, that is exactly what I think, that's why I started this post.
I'm running some Alber@home's at the moment and then I will update to the latest ATI drivers.

So you think nVidia GPUs don't generate invalid results...


EDIT@Rantanplan: with an app_info.xml in the projects folder you don't need to update BOINC.


I'm not thinking that, I'm seeing that. I keep a close eye on the results and from the approximately 45 WU per day on nVidia for Einstein@home none is marked invalid.
I have alos let the machine run a day on Milkyway and even then none where marked invalid.
Einstein and Milkyway on the ATI gives quite amount of invalids, Milkyway way more though.

I don't mind not getting credit, but running WU' that become to often invalid is not what I want.

GPU usage is between 80-99% by CCC.
The 99% is a few seconds when the WU is about to be finished.

But these "invalids" have nothing to do with my system.
With a machine with older version of Boinc and nVidia all WU's are validated for 100%, for Milkyway and Einstein.

Running on ATI with opencl gives "invalids" for both projects.

I have checked all my wingman and they have a lot of "invalids" too when using ATI and opencl. It is something in that software.

I am currently using my ATI/AMD cards at Moo right now but have crunched on and off using them here and have never had a problem. I am currently using my Nvidia cards and don't have a problem either. I have some questions if you don't mind: what kind of AMD card do you have? What driver version are you using? Are you leaving a cpu open while you crunch or are they all busy crunching their own units? What version of Boinc are you using? How much ran does the pc have in it? What OS are you using? Your pc's are hidden so I can't see any of this for myself.

Radon HD 5870 (2)
driver: OpenCL: ATI GPU 0: Cypress (driver version 1016.4 (VM), device version OpenCL 1.2 AMD-APP (1016.4), 1024MB, 991MB available)
i7, 8 core, 6 cores crunch Rosetta@home, so 2 free (0.5CPR per MilkyWay WU)
Boinc 7.0.28
12GB Ram
Win7 Ultimate x64

I have run MilkyWay@home on this PC for 25 months without issues, (all validate) it begun when they update to opencl.
My PC with nVidia run Einstein@home 24/7 and ALL validate. It must be an ATI thing.

And yes I have tried several drivers for ATI wich become a pain to de-install them eventually as they don't have the neatest de-installer.
The latest driver gave errors while running GPU WU's so I am happy with my current drivers, as all the other stuff is working fine.

Since the new update (September 2012) of GPU crunching software (opencl) I (and others) have a lot of invalid's with the ATI cards (I about 20%).
On other PC's with nVidia cards I run Einstein@home on the GPU with no issue's at all and all are valid.
Then I tried this: I run Albert@home on the ATI's and from 6WU's 2 where invalid.
I run Einstein@home on the ATI and approx. 1 in 20 is invalid.

I have run Milkyway@home on the nVidia PC and none, really none, was invalid!

So, perhaps a bold statement but ATI cards are not the best one for crunching as they generate invalids, as all the projects that run on ATI AND nVidia I have tested.
All my new systems will have nViida cards (then I can crunch GPUGRID as well).

I haven't change anything as from September. It all started when there was a change in the searches.
I don't have the latest drivers, I never use them. They resolve some bugs, but create new ones. I even try to use a BOINC version that does what I want, but sometimes a newer is necessary to run certain projects.

I use F-Secure as a AV and FW, and have nothing excluded. They solved all the issues with not uploading and automatically new work, and everything is running smooth and save.

Only Milyway produces a lot on invalids (can't validate, while wingman are validated).


Are you running MW, Gpugrid and Einstein on the same gpu's at the same time? If so set the swap time so no unit gets suspended mid task before it switches to the next task if you can. I never run more than one gpu project at a time on a single pc, a reason to start building towards a 'ranch', which is 15 or more pc's! I tend to focus on a project, giving myself a goal then switching my resources to the next project etc, etc.


No, only one at a time (GPUGRID can not with ATI).
To me it seems going wrong since September when the new searches and the opencl was introduced. Then started the invalids to appear. previous I had 600, 800 even more than 1300 consecutive tasks, now 3, 5, never seen 10 or more.
It also takes way longer to validate (days, several weeks), previous it was minutes to validate.
My 5870 are not the newest cards anymore, but they did great without error and only one per around 2000 validate errors until this summer.

All systems I build myself in the future will have nVidia cards.
For Popo666: The ATI works at 90-92 degrees Celsius, with the fan at 50-55% so no heat problems.

Well I have now 1994 WU's and 211 are invalid with two 5870 cards.
No gaming no other things than two GPU crunching MW and the CPU Rosetta.

Almost two years without problem here at MW, but in the summer they made some changes in the searches, and Travis is less involved an that was when it went wrong. Latest drivers, win7 ultimate, i7, 12Gb ram, three disks and latest BOINC.
Also a lot of errors, but that was fixed by Travis late September.
So no more errors for me but a lot of invalids.

Thats why I sometime crunch Einstein@home on this machine and that results in some invalids too, but way less.
Running Einstein@home 24/7 on a nVidia cards as well on another machine has not given any error or invalid.

Seems to be a combination of the ATI cards and the software (drivers) to me.

If your pc sees only one graphics board it is possible that they are set up in SLI to work as one card. You can disable it in the software of the cards. Via the menu or by clicking on the screen with the right mouse button.

Is anyone from the project actively working on this problem or are we going to waste cruncher's resources until it magically goes away? I moved to Einstein but would rather be back here. Oh well ...


Einstein always steady, a genius after all ;-)

Ovrnight my system ran 1377 WU's with 62 invalid and 37 errors, so that is not to bad. It is already less than a week ago.

I have updated last week the ATI drives as BOINC to latest version for my cards, 5800 series. Errors at MilkyWay arose then, but that was coincidence (I hope).
Travis mentioned they take of the error batch, but errors still occur.
So I guess updating to the latest is not necessary.

I am only getiing edge 1 and 3 and free 1 and 3 and some sample 2 and 3.
They are expected to run the same time as the "old" ones. Edge and free run approx. 20 seconds faster that the "old" ones but I don't know if that is because the new driver.
(I also noticed that the edge and free have 106.99 credits to "old" ones 159.89)

Could it be a graphics driver problem?
I run Albert@home once a while as well and they did okay since yesterday as there are many validate errors too with ati as I saw with wingman. Nvidia seems to be okay.

For edge_1 and edge_3 and free_1 and free_3 still many errors (while computing) and even more validate error for same, however wingman seems to run them fine and get validated.
I have the newest driver 1.4.1741 with HD5870 and BOINC 7.0.28 on Win7 x64.

Hi Steve,

These "things": ps_plum_slice_EMD_NEW_100K_1341346802_25338, error out, not only at my place, also with wingman.
So you have to study a wee bit more on the code...
