Nah, I'm getting the massive overflows from tasks from those tape periods on r3525 also. It isn't just you.

Hi everyone, i've the same with R3330 ...

Not 90%, but more than noticeable with r3430, and cuda50.

. . Hello Raistmer,

. . I was wondering if you had RC status for v8.19/r3528 yet?

Stephen

I hope to get them released at Tuesday. Up to Eric after that.

The only strange thing of r3528 compared with r3500 (beta vs main) is the report/usage of "LotOfMem path"

(Radeon HD 6570 1024MB / Catalyst 11.12 / Windows XP)
http://setiweb.ssl.berkeley.edu/beta/show_host_detail.php?hostid=72429
http://setiathome.berkeley.edu/show_host_detail.php?hostid=4832843

Both apps run on default (no cmdline)

r3528 reports "LotOfMem path: yes"

	Total device global memory: 512MB
	max WG size: 256
	local mem type: Real
	LotOfMem path: yes
	LowPerformanceGPU path: no
	HighPerformanceGPU path: no

"Lot of mem" path has meaning only for SoG.

You mean that setiathome_8.19_windows_intelx86__opencl_ati5_sah.exe is ATI AMD SoG build?

I didn't expected "Total device global memory: 512MB" to be considered "LotOfMem"

EDIT:
OK, I now see "SIGNALS_ON_GPU"

Yes.
And well, it means app considered enough memory to chose that path.
BTW, try to experiment if selection works properly - increase -sbs value - will you see switch to non-LoM path?

. . OK I will not pretend I understand what all that means apart from basically it is a CPU based OpenCL app (am I right?). But it is running pretty well on my Nvidia cards. It is running on all my rigs with GT730, GTX950 and 2 x GTX970. So confused or not I am impressed :)

   OK I will not pretend I understand what all that means apart from basically it is a CPU based OpenCL app (am I right?).

No - I posted 2 links to tasks run on my ATI AMD GPU: Radeon HD 6570 on Computer 4832843 and the same physical Computer 72429 on SETI@home Beta.
Read second line of my post - "second line" of text, not the empty one ;) :

But it is running pretty well on my Nvidia cards

The MultiBeam_Kernels_r35xx.cl file is the same for ATI AMD and NVIDIA but the .exe is different.

"USE_OPENCL_HD5xxx" and "AMD HD5" means ATI AMD Radeon HD 5xxx series (and above)

But it is running pretty well on my Nvidia cards

The MultiBeam_Kernels_r35xx.cl file is the same for ATI AMD and NVIDIA but the .exe is different.

. . OK, so the AMD version of r3500 is not SoG but the Nvidia version is?

. . Always so much to learn.

Ah, indeed. App checks that value and will not try to aquire more than runtime could give.
So, this GPU can't use more than 128M as single allocation. But it has 512Mb total so can allocate enough number of separate buffers for LoM path.
