I added Einstein and set preferences as suggested. How do I find out how fast my GPU is ? I bench-marked my CPU but cant find anything for GPU ? Thanks |

NVidia lists it at 1.0 vs 3.5 for fastest. But I don't know how this compares to my quad CPU at 3.3 GHz. |

NVidia lists it at 1.0 vs 3.5 for fastest. But I don't know how this compares to my quad CPU at 3.3 GHz. A quick look suggests that your GPU isn't a great deal faster (10-20% depending on angle range) than 1 of your CPU cores. Cheers. |

Maybe this list will help you (or at least give you a idea): http://setiathome.berkeley.edu/gpu_list.php |

I have another question, i looked at setting etc and i cant find how to load the GPU with 2 or 3 WU. I am only getting 60 - 70% loading of GPU and temps are around 48C |

I have another question, i looked at setting etc and i cant find how to load the GPU with 2 or 3 WU. You have to make configuration file to do that. There are two choices: 1) Make app_config.xml file. 2) If you have Lunatics installed, Lunatics has created app_info.xml file for you, use app_info.xml file to tell BOINC to do two gpu wu. I have Lunatics installed, so I simply edit my app_info.xml file. From Mike and Josef W. Segur. How to make app_config.xml file. app_config.xml needs to be in {BOINC Data directory}\projects\setiathome.berkeley.edu\ Create an app_config.xml file <app_config> <app> <name>astropulse_v6</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>.5</gpu_usage> <cpu_usage>.2</cpu_usage> </gpu_versions> </app> <app> <name>setiathome_v7</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>.5</gpu_usage> <cpu_usage>.2</cpu_usage> </gpu_versions> </app_config> |

Thanks, I run BOINC and that's why I couldn't find it. |

In event log it says 1/22/2014 1:20:12 PM | | cc_config.xml not found - using defaults 1/22/2014 1:20:12 PM | SETI@home | Found app_config.xml Finds app_config.xml but doesn't load ? still running one GPU WU with 1 GPU What should be in cc_config.xml ? Thanks Ian. |

Which Host are you trying to configure? Earlier you posted nVidia, now I see AMD HD 7700 series... |

Which Host are you trying to configure? Earlier you posted nVidia, now I see AMD HD 7700 series... Well, I just happen to have one of those. It's even on a dual core host. First, you need to update to the latest AMD driver. Second, you DO NOT want to run 2 ATI APs on a dual core host that already has CPU work scheduled. The first time you tried to run 2 heavily blanked APs, it would not be pleasant. You need to use the cmdline settings to raise the gpu usage. Find the file named ap_cmdline_win_x86_SSE2_OpenCL_ATI.txt in the setiathome.berkeley.edu folder and paste the following line in it; -unroll 10 -ffa_block 8192 -ffa_block_fetch 4096 -sbs 256 Next, find the file named mb_cmdline_win_x86_SSE_OpenCL_ATi_HD5.txt and paste the following line in it; -period_iterations_num 32 -instances_per_device 2 -sbs 256 You may have a few mb_cmdline_win_x86 files with a slightly different name. Just paste the same line in each one. Change the app_config.xml to; <app_config> <app> <name>setiathome_v7</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>.5</gpu_usage> <cpu_usage>.04</cpu_usage> </gpu_versions> </app> </app_config> See how that works. |

I dont have a file ap_cmdline_win_x86_SSE2_OpenCL_ATI.txt Only mb_cmdline-7.03-opencl_ati_sah mb_cmdline-7.03-opencl_ati5_sah So I pasted into these files, note they were empty ?? |

I dont have a file ap_cmdline_win_x86_SSE2_OpenCL_ATI.txt All xx_cmdline_...txt files are installed empty. The User has to enter the applicable settings. You should have an AstroPulse Command-Line file named ap_cmdline_something.txt. That's the one whose settings will speedup the AP tasks. The driver you are using is from around August 2012. It's probably one of the first drivers to support the HD 7770. You really should update it. |

Well that's interesting about the driver. I went to system drivers, and update and it said driver was up to date. obviously not !! downloading from AMD site now... |

It reinstalled catalyst. Driver is now Dec 2013. Re starting after changes will let you know. |

With the newer driver, you should delete all the .bin, .bin_V6, .bin_V7, & .wisdom files so newer ones can be compiled. It will probably work with the older files, but it will work better with new files compiled with the newer driver. You can see some of the files here; Delete all the MB_clFFTplan...bin, AP_clFFTplan...bin, MultiBeam...bin_V7, AstroPulse...bin_V6, and xxx.wisdom files. |

double checked everything and still running one GPU WU. It says .35 CPU + 1 ATI GPU |

double checked everything and still running one GPU WU. It says Can you post the contents of your app_config.xml please, make sure it is from the setiathome project directory. Claggy |
