Message 1738642 - Posted: 31 Oct 2015, 21:39:01 UTC

I hear there has been a problem for a long time with OpenCL on ATI GPUs for iMacs with the ATI Radeon HD 4670 for a long time. I had some hope this would be fixed with the SETI@home 7.08 version, but the problem persisted...at least for me. Until today.

BOINC claimed it completed ONE of the 45 or so units it downloaded, even though there were some errors in the sterr.txt The rest dumped with Computation Errors right away.

I wonder what was different with this ONE special unit that made it claim to work. It would sure be nice if they all did.

Forgot to mention. I had chalked the success up to running the latest Mac OS X update, bringing this machine up to 10.11.1. This was the first unit run after the update, so I thought the update fixed something. Until all the rest of them dumped.

Worth to look into stderr log that posted in task details on web site:

WARNING: This application needs newer GPU, at least ATI Radeon HD 5000 needed, exiting !

App not supposed to run on your GPU at all. Wording "WARNING" along with "exiting" little deceiving. ERROR would be more appropriate in such case cause execution can not be continued.
And the reason of error - GPU task issued to unsupported GPU. Error in plan_class that allowed such action.
Pity that beta testing did not discover that missing in plan class.

Message 1738760 - Posted: 1 Nov 2015, 12:13:48 UTC

There are three OpenCL ATI Mac OS X apps each coming with a plan_class :

- opencl_ati5zc_mac (for ATI Radeon HD 5000 and newer GPUs)
- opencl_ati5_mac (for ATI Radeon HD 5000 and newer GPUs)

- opencl_ati_mac (for ATI Radeon HD 4000 and newer GPUs)

The first two app versions throw the error-message that Raistmer found when run on ATI HD 4000, because there was no way to exclude the ATI HD 4000 generation of GPUs via a plan_class from getting these apps (until time of release). Therefor the app itself had to warn the user and exit with an error before doing anything.

The last app version is the one with the problem. Here is a stderr with the error that is thrown, because of app failure :

Looking at the host it doesn't appear that it can successfully run any OpenCL app. My understanding was that there is nothing about the ati5 apps that prevent them from running on pre-ati5 architectures. They are just written to execute slightly differently for better performance on different GPUs. I suspect that this is a problem with whatever AMD/ATI driver is being used. AMD/ATI has a habit of ignoring problems new drivers cause on older hardware.

Since AMD/ATI removed CAL HW version from their drivers, there's no way in the current BOINC code to exclude a ATI GPU based upon a device hardware version on a Mac. On PCs with old drivers we can still use CAL version. But for Mac, the best we have now is OpenCL version, but AMD reserves the right to uninvite specific hardware and specific operating systems from the party with each new driver release.

I see. Pity that BOINC doesn't able to parse clInfo in right degree to see that HD4xxx hardware present. As one can see from app's own output it is doable.

We don't really have the resources to chase what GPU manufacturers name their cards (ATI is out of meaningful 4 digit numbers) or whether their cards live up to the standards they claim to follow. A name is a marketing device, not an engineering standard. An HD4760 may have nothing to do with what an HD4762 or an HDR4760 are capable of. An HD4760 manufactured in 2016 could be entirely different from one made in 2014.

I guess I'll look through and see whether any OpenCL 1.0 cards are able to run 7.08 on Macintosh. If the answer is no, I can bump the requirement to OpenCL 1.1.

Would prefer to find out why one the ATI HD 4000 app works on Windows and Linux, but not on Mac OS X.

Sadly no one has reacted to my call for help over the last two weeks, so no testing resources are available.

If I thought it would help I'd try my PC4670 in my Mac. However, I don't see how a full sized PC card would give the same environment as the Mini that's in an iMac. Plus, I don't even know if the PC4670 would work with OpenCL in a Mac, I know it will give an image on the screen.

Here's another OpenCL 1.0 Card on a Mac, http://setiathome.berkeley.edu/results.php?hostid=4698278

BTW, I think I just got Robbed by two of those notoriously unreliable Mac Intel GPUs. From my experience the Intel GPU AP App isn't to be trusted, My GPU meanwhile HAD a spotless record, http://setiathome.berkeley.edu/workunit.php?wuid=1921981215

Would be great if you could try to reproduce that error in a standalone run with -v 2 option set. That could bring us a little closer to where in code the error happens.

Could we stay on topic please. As long as the validator validates the way it does we all get "robbed" from time to time.

Well, in my book, the Hosts returning the Errors aren't really a problem. The Host returning 'Successful' tasks that are Invalid, but chosen as Valid results when they team up Are a problem. My new card had Never received an Invalid in over 1100 AP tasks, the other Two have Very recently received Invalids. Just look at the Host Details pages and note the Consecutive number and the Completed numbers.

I'll look into the 4670 later today.

We don't really have the resources to chase what GPU manufacturers name their cards

But on the other hand, can't you just filter on "Radeon HD 4670"?
The newer GPUs from AMD are no longer called "HD XXXX" but "Rn XXX", e.g. R5 270, R7 280, R9 290.

No other GPU manufacturer calls his GPU Radeon, that's property from AMD/ATI.
The BOINC client sends that whole name along with scheduler requests, in Jonathan's case AMD Radeon HD 4670 (256MB), so I don't see why you can't have the server tell that scheduler/work requests with that sequence should not be sent applications for the 5xxx style GPUs and better.

As for why the 5xxx style applications don't work on these GPUs, isn't that because these GPUs can only run the Multibeam application at a maximum workgroup size 128, where the workgroup size for the 5xxx apps is 256 (or more)?

If I thought it would help I'd try my PC4670 in my Mac. However, I don't see how a full sized PC card would give the same environment as the Mini that's in an iMac. Plus, I don't even know if the PC4670 would work with OpenCL in a Mac, I know it will give an image on the screen.
Would be great if you could try to reproduce that error in a standalone run with -v 2 option set. That could bring us a little closer to where in code the error happens.

Here's another OpenCL 1.0 Card on a Mac, http://setiathome.berkeley.edu/results.php?hostid=4698278
, which finishes workunits sporadically successful : other problem !

I just happened to think...I don't have the App to test. doh.

So, remember that App I posted on Beta a while back? Said it MIGHT work on the HD4 cards. Well, it appears to work on My HD4 card. At least on bench. BOINC says;

If I thought it would help I'd try my PC4670 in my Mac. However, I don't see how a full sized PC card would give the same environment as the Mini that's in an iMac. Plus, I don't even know if the PC4670 would work with OpenCL in a Mac, I know it will give an image on the screen.
Would be great if you could try to reproduce that error in a standalone run with -v 2 option set. That could bring us a little closer to where in code the error happens.

Here's another OpenCL 1.0 Card on a Mac, http://setiathome.berkeley.edu/results.php?hostid=4698278
, which finishes workunits sporadically successful : other problem !

BTW, I think I just got Robbed by two of those notoriously unreliable Mac Intel GPUs. From my experience the Intel GPU AP App isn't to be trusted, My GPU meanwhile HAD a spotless record, http://setiathome.berkeley.edu/workunit.php?wuid=1921981215
I wuz Robbed...
Could we stay on topic please. As long as the validator validates the way it does we all get "robbed" from time to time.

Well, in my book, the Hosts returning the Errors aren't really a problem. The Host returning 'Successful' tasks that are Invalid, but chosen as Valid results when they team up Are a problem. My new card had Never received an Invalid in over 1100 AP tasks, the other Two have Very recently received Invalids. Just look at the Host Details pages and note the Consecutive number and the Completed numbers.

I'll look into the 4670 later today.

OK, WTH is this? http://setiathome.berkeley.edu/workunit.php?wuid=1922047397
How can you get an Invalid on a Blanking too much RFI? percent blanked: 100.00
I think I see a pattern here. I was sent a Resend, the other Host completed the task before I did.
So, I GET AN INVALID! For Successfully completing the Resend that was sent Me?
I remember this from a long time ago, Why has it resurfaced?
Not happy...

Oh, the 4670 is running a shorty offline.

So, it appears the App works fine the First time it's run on the Radeon 4670, however if you restart the App or run it the second time it Errors out. Seems the problem is the Kernel file it leaves after running. The file MultiBeam_Kernels_r2934.cl_RadeonHD4670.bin_V7_13.4.0_10 is the Only kernel file it leaves behind, if you Remove that file before starting the App, it appears to run normally. If the file is present during launch you receive the Error;

It doesn't leave the other Kernel files after running, it shouldn't leave this one either.

It took a little longer running under BOINC. My guess is the 4670 doesn't like the oclFFT Plan, back when first trying the new APv7 App it gave much longer times using the oclFFT settings.
But it did finish, http://setiathome.berkeley.edu/result.php?resultid=4492978697

I just happened to think...I don't have the App to test. doh.

TBar, check your client_state.xml for the download url. At Beta it was
http://boinc2.ssl.berkeley.edu/beta/download/setiathome_7.08_x86_64-apple-darwin__opencl_ati_mac (or similar => r2936)

Please use -v 2 commandline option.
