I am new to the seti@home. I have done folding@home in the past. I had a few questions. i can see that several jobs are running at the same time but my gpu stay at 65%. my cpu stays at 100% i have read on these forums that i need to add a App_config.xml file to get the max usage out of the gpu. when i add the app_config.xml to the data folder and start Boinic manager it give me this error : SETI@home: Notice from BOINC unexpected text '[' in app_config.xml I would also like to know what seti@home is really looking for? is it really wanting cpu or gpu. it seems to really use the cpu more then the gpu. I was thinking about building a seti@home system. also which is better amd or intl cpu for seti@home. it seem that the software is written more for the AMD/ATI side of the house than the intel/nvidia side. after running two systems for 24 hours my score is 14.380. i feel i am doing something wrong here and any help anyone could give me, I would be a grateful. here is a link to the two systems i am using. http://setiathome.berkeley.edu/hosts_user.php?userid=10302106 [url][/url] |

Show the text of your app_config so we can figure out what is wrong. |

There are two types of work units. GPU work units. Use cpu and gpu. CPU work units. Use cpu. Recently I changed my setup to only run GPU work units. I have dual core cpu, which means that two cores is a 1, one core is 0.5 of cpu. I am running two gpu work units and I want to use one core total so I assigned 0.25 of cpu to each gpu work unit, for a total of 0.5 of cpu. My app_config.xml is this: <app_config> <app> <name>astropulse_v7</name> <gpu_versions> <gpu_usage>1</gpu_usage> <cpu_usage>1</cpu_usage> </gpu_versions> </app> <app> <name>setiathome_v8</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.25</cpu_usage> </gpu_versions> </app> </app_config> |

Also. Get a proper editor to write code, I highly recommend Notepad++. |

thank you Spitfire. your code worked great for me. Below is what I used. gpu is now 94%. cpu is 13%. <app_config> <app> <name>setiathome_v8</name> <max_concurrent>3</max_concurrent> <gpu_versions> <gpu_usage>0.25</gpu_usage> <cpu_usage>0.5</cpu_usage> </gpu_versions> </app> </app_config> |

thank you Spitfire. your code worked great for me. Below is what I used. gpu is now 94%. cpu is 13%. Just for kicks try running 8 work units on the 2 GB card. I did it once on my 2 GB GTX 460, wanted to see how many task would fit before I ran out of ram. I used GPU-z to monitor the card/ram usage. |

IONK you app_config is ok for seti V8 M/B's but you can't do Astropulse with that app_config This is mine witch will allow you to do Astropulse V7 units on the gpu as well
<app_version> <app_name>setiathome_v8</app_name> <plan_class>cuda50</plan_class> <avg_ncpus>0.15</avg_ncpus> <ngpus>0.5</ngpus> </app_version> <app_version> <app_name>setiathome_v8</app_name> <plan_class>cuda42</plan_class> <avg_ncpus>0.15</avg_ncpus> <ngpus>0.5</ngpus> </app_version> <app_version> <app_name>setiathome_v8</app_name> <plan_class>cuda32</plan_class> <avg_ncpus>0.15</avg_ncpus> <ngpus>0.5</ngpus> </app_version> <app_version> <app_name>astropulse_v7</app_name> <plan_class>opencl_nvidia_100</plan_class> <avg_ncpus>0.2</avg_ncpus> <ngpus>0.5</ngpus> </app_version> </app_config>
<app> <name>setiathome_v8</name> <max_concurrent>3</max_concurrent> <gpu_versions> <gpu_usage>0.25</gpu_usage> <cpu_usage>0.5</cpu_usage> </gpu_versions> </app>
<name>astropulse V7</name> Also I would change your <cpu_usage>0.5</cpu_usage> to <cpu_usage>0.2</cpu_usage> as you don't need 0.5 for the cpu 0.2 is more than enough I'm using 0.15 and times are better than using 0.5 |

right now with three jobs its using 893 meg of ram on the video card. How many Cpu cores are you using thou ? 0.5 would mean your using 2 you can set it lower as the cpu is only used to feed the gpu average time is 30mins per unit I do 4 units with the 680 gtx and i only use 1 core for all 4 units and then i do 7 cpu units so that's 11 at one time Ap's thou with the AMD FX chip will need 1 core per unit so i can only do a max of 8 units at a time 2 GPU 6 CPU and i have it set for 0.5 cpu's it's the FX chip so if you have Intel this is not so much of a problem i believe . |

Darth Beaver, I wanted to be able to run on the gpu and not the cpu. That way I can still use the system while its doing its thing for Seti. thanks everyone. |

On your account page look at your " computing preferences" and untick " use cpu" if you only want to use you gpu for seti just make sure you do that for the venue the computer is on eg home , work etc Life is what you make of it :-) When i'm good i'm very good , but when i'm bad i'm shi#eloads better ;-) In't I " buttercups " p.m.s.l at authoritie !!;-) |

Darth Beaver, I run on both the CPU & GPU while using the system for other things with no issues, as do many others. Grant Darwin NT |

Darth Beaver, In fact both of your Intel systems would do very well using both CPU and GPU's, especially if you have good cooling in place, but that AMD (lappie?) rig I'd forget about myself (though there maybe a few who will disagree). ;-) Cheers. |

I quite happily run tasks on both CPU & GPUs, the only time I have to suspend SETI is when I head off into the wilds running large CFD or CAD models (some of the CFD stuff runs for days on a system with two GTX980 and an 8-core AMD). For more "sane" use there is little impact from running on both. However, your dual core AMD system may be a bit more prone to screen lags etc. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |
