Is there anything I have to set in a stock installation to enable GPU AP downloads? I wouldn't think so but I've been getting CPU APs all day but even though my CPU cache is full and my GPU cache isn't (I disabled SETI@home in my preferences), it won't get an AP GPU task. Maybe my GPU isn't known but it's been running MB GPU tasks successfully for the last few days. Here is the start of my event log to show what I've got. 15/11/2015 20:08:03 | | cc_config.xml not found - using defaults 15/11/2015 20:08:04 | | Starting BOINC client version 7.6.9 for windows_x86_64 15/11/2015 20:08:04 | | log flags: file_xfer, sched_ops, task 15/11/2015 20:08:04 | | Libraries: libcurl/7.39.0 OpenSSL/1.0.2a zlib/1.2.8 15/11/2015 20:08:04 | | Data directory: C:\ProgramData\BOINC 15/11/2015 20:08:04 | | Running under account rick 15/11/2015 20:08:07 | | CUDA: NVIDIA GPU 0: Quadro K620 (driver version 353.82, CUDA version 7.5, compute capability 5.0, 2048MB, 1968MB available, 863 GFLOPS peak) 15/11/2015 20:08:07 | | Host name: RickAtHome 15/11/2015 20:08:07 | | Processor: 8 GenuineIntel Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz [Family 6 Model 60 Stepping 3] 15/11/2015 20:08:07 | | Processor features: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss htt tm pni ssse3 fma cx16 sse4_1 sse4_2 movebe popcnt aes f16c rdrandsyscall nx lm avx avx2 vmx smx tm2 pbe fsgsbase bmi1 smep bmi2 15/11/2015 20:08:07 | | OS: Microsoft Windows 7: Professional x64 Edition, Service Pack 1, (06.01.7601.00) 15/11/2015 20:08:07 | | Memory: 7.92 GB physical, 15.84 GB virtual 15/11/2015 20:08:07 | | Disk: 916.73 GB total, 869.21 GB free I've been through various documentation including this forum but found nothing.

You can ask for AP under your preferences in your My account, middle of the page. Make sure you have Astropulse v7 clicked. But I don't think that is your problem. Obviously you have the Use GPU as you stated MBs are being crunched. Looking at your start up, I don't see any OpenCl listed in there. Normally you would see something along the line of OpenCL: NVIDIA GPU 0:Quadro K620 (driver version 353.82, device version OpenCL 1.2, 2048MB.etc) So I have to wonder if the OpenCL was not installed on your machine. If that is the case, it might just be as simple as a clean install of the nvidia driver from the nvidia website. Looking at Nvidia website for the K620, it say it supports OpenCL Happy Crunching Zalster |

Thanks, you're right about the Open CL. I'll look into that tomorrow as I'm likely to make a mistake when I'm this tired. That would mean that MB GPU processing doesn't use it. In fact I think they use CUDA. The task names I've seen include CUDA 42 and CUDA 50 in their name which implies that. Ta. Rick |

I've given up on this. I'll accept what I can get for now. OpenCL was actually downloaded with the driver install in two versions, OpenCL.dll and OpenCL64.dll, in Program Files. I did a search of Windows and there is an OpenCL32.dll and an OpenCL64.dll installed in the right place and with the same date and time as the downloaded versions. So the installation was correct and complete. So either the GPU wasn't set up to use OpenCL, or seti cannot recognise that it is. I downloaded and ran GPU-Z just in case it found what seti couldn't, but it also couldn't find OpenCL. As I said, I'm giving up for now but if I ever sort this out I'll report back to this thread. |

... or seti cannot recognise that it is. This should be "BOINC cannot recognise" ran GPU-Z just in case it found what seti couldn't, but it also couldn't find OpenCL Try also: GPU Caps Viewer http://www.ozone3d.net/gpu_caps_viewer/ If it also don't find OpenCL and/or can't run "OpenCL demos" something is wrong with your OpenCL installation.

Did you do a "Clean Installation" of the driver from the Nvidia/Gforce website, or did you get the driver from somewhere else (e.g. MS updates) Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

This was a new machine so I didn't install anything. However when I was searching for an answer I came across a similar problem on a different NVIDIA GPU where they uninstalled and reinstalled the drivers so I did that. I downloaded DDU to do a clean uninstall and downloaded the drivers from my OEM. Running those fixed the problem. GPU-Z and BOINC both recognise that it is OpenCL capable. E.g. BOINC now logs this: 19/11/2015 00:48:55 | | CUDA: NVIDIA GPU 0: Quadro K620 (driver version 348.17, CUDA version 7.0, compute capability 5.0, 2048MB, 1947MB available, 863 GFLOPS peak) 19/11/2015 00:48:55 | | OpenCL: NVIDIA GPU 0: Quadro K620 (driver version 348.17, device version OpenCL 1.1 CUDA, 2048MB, 1947MB available, 863 GFLOPS peak) Thanks for your help.

...now all you've got to do is snag a couple AstroPulse tasks and see that GPU strut its stuff. Trouble is Astroplulse there aren't being produced right now - hang on a couple of days for some new "tapes" to be loaded.

I've had one resend which I pushed to the front and it completed and validated OK. it's strange that it went to the GPU as my CPU cache isn't full but I'm happy with that. |
