Boinc does not recognize OpenCL (Nvidia GTS450)
(Message 46890)
Posted 22 Dec 2012 by Magiceye04 Post: The PC was set up new last month. I installed Windows7, then the Nvidia Driver (direct from Nvidia) und then Boinc. The first weeks i only crunched for seti@home and after a while i tried poem@home but then i got openCL errors. So it is not possible to set a flag or anything like this in a config file to tell Boinc that there IS openCL ? |

Posted 21 Dec 2012 by Magiceye04 Post: Hi! Boinc does not recognize OpenCL capability on my Nvidia GTS450 GPU. When i start Boinc there is only one Message regarding the GPU: ... 11.12.2012 20:41:57 | | Local time is UTC +1 hours 11.12.2012 20:41:57 | | NVIDIA GPU 0: GeForce GTS 450 (driver version 306.97, CUDA version 5.0, compute capability 2.1, 1024MB, 8381345MB available, 568 GFLOPS peak) 11.12.2012 20:41:57 | | No general preferences found - using defaults ...

Only Boinc seems not be able to detect OpenCL. Windows=7Home64 CPU FX-8350, 16GB RAM I tried this: Boinc completely new installed (7.0.28) Geforce-Driver completely new installed (306.97) The GPU-App of Poem@Home from another user copied on my computer and several app_info.xml from other users that work on their PCs. GPU-Projects that dont need OpenCL such as Seti@Home or Einstein@Home work fine. Any further suggestions? MagicEye04 |

cc_config.xml - exclusive_gpu_app - doesn't work correct

Posted 26 Sep 2010 by Magiceye04 Post: [quote]...Make sure you run BOINC and the GPU "based on preferences" as well. If they're set to run always, even this option in cc_config.xml will be ignored. Thanks, the run always option was my mistake. Without that option now it works correcly. :) |

Posted 24 Sep 2010 by Magiceye04 Post: I created this cc_config.xml :
<cc_config>
<options>
<exclusive_gpu_app>DScaler.exe</exclusive_gpu_app>
<exclusive_gpu_app>vlc.exe</exclusive_gpu_app>
<exclusive_gpu_app>mpc-hc.exe</exclusive_gpu_app>
</options>
</cc_config>
...and the first days it worked fine. When i started one of the programs, the GPU-Task stopped immediately und continued after closing the program. But one day i noticed, that now it doesn't work any more. When i start one of the programs, GPU-Task is still running. :( When i shortly suspend the task manually and continue it 1 second later, then it stays "waiting to run" - also if i close the program. Again it helps to suspend the task manually for a second an then it continues computation. So i think, the BOINC Manager is detecting the running program but is not able to react. Any idea, how to get this to automatic GPU-suspending function working correctly? 24/09/2010 19:12:55 Starting BOINC client version 6.10.58 for windows_intelx86 24/09/2010 19:12:55 Config: don't use GPUs while DScaler.exe is running 24/09/2010 19:12:55 Config: don't use GPUs while vlc.exe is running 24/09/2010 19:12:55 Config: don't use GPUs while mpc-hc.exe is running 24/09/2010 19:12:55 log flags: file_xfer, sched_ops, task 24/09/2010 19:12:55 Libraries: libcurl/7.19.7 OpenSSL/0.9.8l zlib/1.2.3 24/09/2010 19:12:55 Data directory: G:\Boinc 24/09/2010 19:12:55 Running under account Andreas 24/09/2010 19:12:55 Processor: 4 AuthenticAMD AMD Phenom(tm) II X4 905e Processor [Family 16 Model 4 Stepping 2] 24/09/2010 19:12:55 Processor: 512.00 KB cache 24/09/2010 19:12:55 Processor features: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 htt pni cx16 syscall nx lm svm sse4a osvw ibs skinit wdt page1gb rdtscp 3dnowext 3dnow 24/09/2010 19:12:55 OS: Microsoft Windows XP: Professional x86 Edition, Service Pack 3, (05.01.2600.00) 24/09/2010 19:12:55 Memory: 3.00 GB physical, 3.34 GB virtual 24/09/2010 19:12:55 Disk: 428.97 GB total, 209.19 GB free 24/09/2010 19:12:55 Local time is UTC +2 hours 24/09/2010 19:12:55 NVIDIA GPU 0: GeForce 9600 GT (driver version 19634, CUDA version 3000, compute capability 1.1, 512MB, 192 GFLOPS peak) |
