Observation: 1761 produced "WARNING: suboptimal workgroup size for PC_find_pulse_kernel_cl pass x" in stderr. From a quick look at the source I think that's just about wasteful memory alignment, shouldn't have much to do with speed.

Actually it can affect performace. Suboptibal workgroup size meand underloading GPU. Could you give link on result with that warning ?


I had tons of those Warnings too, but only on the VHAR's. Changing -sbs 256 to -sbs 128 was the solution for me. Changing the value in -period_iterations_num didn't make any difference whatsoever, the warnings for suboptimal workgroup size, still appeared.

No more of those warnings when changing to -sbs 128 though.


But the app is slower with this setting.
400 seconds running 3 instances on a 0.41 on my 5850.


Well, I didn't notice any big slowdown when going from 256 to 128. Only a couple of seconds slower on a VHAR, and maybe 10-15 seconds slower on a mid range WU. That I can live with, knowing that I do not pollute stderr with lots of Warnings, even though those warnings are mostly of a cosmetic nature.

Edit: Looking at your stderr files, you have yours set at: Maximum single buffer size set to:156MB, and not 256 MB

Yes, i only have a 1GB card.
So reducing -sbs to 156 is required running 3 instances.
~900 MB in use with actual settings.

I see. Well, I have time to experiment more with this during this Easter holiday. Next is to test running 2 AP's. First I will run down the cache a bit though, because I have hundreds and hundreds of Beta WU's clogging the pipe :-)

Message 1361882 - Posted: 27 Apr 2013, 17:44:33 UTC

AMD recently released their 13.4 drivers which comes with a new OpenCL driver, 1124.2.

Has anyone tried them yet with r1760 MB app? I'm still on r390 due to my reluctance to mix and match my driver packages since I was told the OpenCL driver that came with 13.1, 1084.4 was buggy with r1760. Basically it crashed with 1084.4.

I don't do Astropulse so please don't talk about the Astropulse apps to me, this is only about the r1760 MB.

The r176x MB and AP apps don't work with Cat 13.2 Beta, Cat 13.3 Beta or Cat 13.4 (they all use the same APP 1124.2 runtime, compilations would fail because of the compiler failng to work with the build option "-fno-bin-llvmir")

New apps that work with Cat 12.10, Cat 13.2 Beta, Cat 13.3 Beta and Cat 13.4 were released two days ago (Cat 13.1 should still be avoided):

Just to be crystal clear, r1817 will work with the version 1124.2 OpenCL driver. I just don't want to go through the mess that I went though the last time with all the refetches of GPU workunits, which I admit isn't as daunting anymore with the new big pipe.

Yes, it will work.
I`m running r1812 with new drivers.

Thank you.

I'll probably let the cache drain so I can also upgrade to the latest BOINC as well.

Are there any limitations on these Apps? Will they work in Windows XP with Catalyst 11.12? I'm currently trying my 6850 in Windows 8 with Catalyst 12.8 just to see if there is any difference between XP & 8. Even though the GPU usage in staying pretty much in the low 90% range with Win 8, the completion times are almost identical to those in XP. About the only difference is the card runs hotter in the Win 8 Host. I'll probably move it back to an XP Host with Cat 11.12.

This line, "For overflowed tasks found signal sequence not always match CPU version". Someone needs to tell the Validator about that. I'm so tired of just about every overflow coming up 'Inconclusive'. Now they've called in another CPU so it too can come up with 30/30 Exiting...

I have tested the new apps with Cat 12.1 (851.4) which is based on SDK 2.6 same as 11.12.
It ran fine.
So it should work.

They built with SDK 2.6 so drivers that 2.6 supports and up required. The single known exclusion is Cat 13.1 that not compatible. Its compiler produces garbage code and no workaroud found so far.

Nice. So as long as you use the last two AMD drivers that work with BOINC in XP you are good. Thanks for including XP in your new App.

What!? We get experience points crunching with OpenCL apps. Can I level up my Seti skill and crunch faster? :p

Yes we do. After a given amount of time you can unlock the Epic Power Bill achievement.

One shouldn't take XP support quite so lightly around here. From what I understand, someone around here is about to release software that doesn't support XP. As for Raistmers' new AP App, not only does it support XP, it also still supports my ATI 4670 in XP. Soon, you will see threads about missing XP support...

XP will be dropped for stock app. We can't load our undermanned SETI staff with support that AMD itself already dropped completely. They refuse to do anything (uninstall utility for example) for XP. As for HD4xxx btw.
So, we will try to keep XP compatibility while it will cost not too much. But after only already released binaries will remain...

When XP support is dropped, will we be allowed to Merge our XP Hosts to a different machine? I already tried to merge the XP from my Mac to a Windows PC, it didn't work. I will not be buying another version of Windows for my old Mac. So, I would of liked to have transferred the Host to a real Windows PC. Or even better, when OSX GPU Apps are finally released, merge my Mac' XP to OSX Lion on the same machine, that would work...for me :-)

You can not merge dissimilar hosts. However you can move your data to a new machine if you wish to maintain the machine ID.

Hmmmm, after a few hundred tasks using MB7_win_x86_SSE_OpenCL_ATi_HD5_r1817.exe, the App produced another Overflow the SETI Validator didn't like. Any idea what could have angered the Validator on this particular task?
