I have a Win 7 PC, i7-4770K proc, GTX 650Ti GPU. I use it as a primary workstation and I am heavy power user; running S@H for fun. Currently using stock app (BOINC 7.0.4.64) for 1 app on GPU, 2 at a time on CPU. Does anybody have input on running more than one task at a time on the 650Ti? I found this app_config.xml suggestion posted by Claggy a few weeks back for somebody running a Titan: <app_config> <app> <name>astropulse_v6</name> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> <app> <name>setiathome_v7</name> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> </app_config> I follow the settings for GPU, but am not sure what to set the cpu_uasge lines for? For now I want to leave CPU tasks as is. And to confirm, this should go in C:\Users\All Users\BOINC, correct? I appreciate the patience and indulgence of the pros on this matter for what must be the umpteenth time in discussing it! |

And to confirm, this should go in C:\Users\All Users\BOINC, correct? Only if that's where you placed your BOINC data directory. Hint: this isn't the default location, so if you didn't change the default, then no, this is not the place it should go. The default location is in a hidden folder called C:\ProgramData\BOINC. You'll want to put the app_config.xml file in C:\ProgramData\BOINC\projects\setiathome.berkeley.edu\ folder. |

The path on my Win7 machines is: C:\ProgramData\BOINC\projects\setiathome.berkeley.edu The file name (Hen using the older "app_info" approach) is: app_info.xml So I'd assume that the newer "app_config" approach would be: app_config.xml Good luck Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Interestingly, following the paths suggested by you both get to the same data path as where I suggested (but I did not go deep enough down the tree). :-) Now, ready for some input on whether the card should handle the extra task, and the particular on the cpu_usage line! |

"ProgramData" is NOT the same path as "User/...". By default it is hidden under Win7 (a real pain given how much use is made of it). Will your GTX750ti do two at a time? - with ease. Each WU will be slightly slower than doing one at a time, net (WU/hr) will be nearly double. It is worth trying other values for the CPU_usage value, I've found the default 0.04 to be a bit conservative. Start with 0.04 for a couple of weeks, then try increasing it slightly to see what happens. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

The Astropulse tasks will need more than .04 - the usual recommendation is to reserve a full core for each AP task. I sometimes experiment with lower values. Also, the .04 value for S@H v7 won't preclude crunching a cpu task, but reserving a full core for each AP task will. I use .1 for S@H but mileage varies, etc. Agree with Rob, the 650 ti should do 2 at a time fairly well.

Start with 0.04 for a couple of weeks, then try increasing it slightly to see what happens. As I've told told you before, the cpu_usage value is used as a management feature by Boinc, once all those 0.04's add up to 1, Boinc will then run one less CPU app, What it Won't do is change the amount of CPU usage used by the GPU app, it'll use what it needs. If you want to make sure that Cuda GPU app is fed well enough then adjust the priority settings in the mbcuda.cfg file, either to 'normal' or 'abovenormal' rather than the default 'below normal' Claggy |

Right now, my app is showing the GPU running a task with 1 CPU and 0.0828 CPU. So maybe set cpu_usage at .17? Sorry if I'm being obtuse on understanding this. Now for the fallback question: If I just want to get back to where I am now, do I just remove the xml file and restart BOINC? Sounds logical, but... |

Is it only running one? Don't double the actual usage per task. The cpu value is per instance. As Claggy points out, the difference won't affect anything, so leave it at .04. Yes, just remove or rename that file to not have it read at BOINC startup. And I assume that the BOINC version in your first post was just a typo and you have 7.0.64?

Yep, that's me. Can't type and chew gum at the same time! Correct on both of my typos... I plunked the xml file as I had it pasted into place. Running 2 GPU apps and all seems well! Should I expect any screen degradation on anything? |

You might experience some lag, it depends a lot on the system and other activity. I set my computing preferences in BOINC to not use while computer is in use. Then I set the activity menu to ignore those prefences (use gpu always). That way I can toggle them on pretty easily when I'm doing something important.

So why are you being obtuse? Why are you keeping your computers hidden? That causes lots of problems for people trying to help you. |

Uh, I didn't realize my computer was hidden? Reason for my self deprecation was that I am generally a technical person (long career in IT). When it come to logic, though, like scripts and settings though, I just seem to go deer in the headlights. |

Uh, I didn't realize my computer was hidden? I think that may be the default on new accounts. Been so long, I could not be sure. Point is, what is being asked is that you unhide them. It makes it possible for others to look at their work and results, and presents no security problems at all, they cannot access your account, just view what your computers are doing. It may take a bit for the servers to update things once you make the change, so don't be surprised if it take a few hours or so. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Thanks, Mark: I've followed your many posts over time. I've actually been around quite a while (3 years). I still don't see where to hide/unhide my PC? Besides, I thought I provided a pretty good description (typos not withstanding) in my original post... |

Thanks, Mark: Home account page. Seti@home preferences. Should Seti@home show your computers on it's website. YES. Hit the update button. Wait a bit. Meow. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Found the preference setting and updated. Thank you all for the configuration advice and other helpful comments! |
