So, I'm currently having an issue with seti on my new system. If I let seti use 100% CPU, my GPU hardly does any load, roughly 12-15%. I can also tell that it's not doing as much work, as the project the GPU is working on crawls along really slowly. Now, if I throttle the CPU down to 1%, the GPU happily sits around 81% usage, sometimes goes near 90%. This is all good and well. But once I start upping the CPU allowance, it all goes downhill from there. I've spent more time than I would like trying to find a useful configuration to fix this issue. I would like to run just 1 WU at a time, and have the CPU and GPU process the same WU until it is done. Right now, it's processing 8 WU's at a time, and with my 1% CPU throttling, it's going to take days to finish :( If anyone could help me with a config to load into BOINC, I would love you forever. I tried using this config, but it didn't seem to work. <app> <name>setiathome</name> <max_concurrent>1</max_concurrent> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>1.0</cpu_usage> </gpu_versions> </app> </app_config> Any tips from the config pros? |

Oh, and I have no idea why it says I'm administrator. *Shrug* I created this account back in 2006. |

In Boinc manager settings choose on multiprocessors use only 84% of CPU. This reserves 2 CPU cores. Works fine with my FX 8150 and HD 7970. With each crime and every kindness we birth our future. |

Mike, you're a genious! Have a look at it now, MUCH MUCH MUCH better. Hats off sir, you've just made my day. |

To change the "administrator", you need to go to the account page, then go to other account informations (not sure is that is the name because i use a portugues version - located in the same line where you change you e-mail adrress) and then change your nick name as you wish. |

Thanks Juan. Done :) Anytime. Just a tip, your GPU could easely run more than 1 WU at a time, check with Mike the best configuration to do that (he uses ATI like you) and don´t forget, it´s a good practice to increase the fan speed when you crunch with the GPU´s they will run hotter than normal. |

I tried using this config, but it didn't seem to work. That's because that is set up wrong, for Seti v6 the name is <name>setiathome_enhanced</name> for v7 it's <name>setiathome_v7</name> it's also missing the opening tag, try the following (you can remove the <max_concurrent> line if you wish): <app_config> <app> <name>setiathome_v7</name> <max_concurrent>8</max_concurrent> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>1.0</cpu_usage> </gpu_versions> </app> </app_config> Claggy |
