I will ask if there is a way to optimize this filter, I'm not sure the ease of it though. Please, if you can ask an option to get wu for GPU only. Tnx |

Settings>Device manager>device name. Click on the profile for that device. Scroll down to processor usage and under Allow research to run on my CPU? select no. below that is Graphics Card Usage. Select yes for use GPU and select the type of GPU. Scroll down to bottom and select save. Done.

Tnx There are options for that in your profile settings. To get opng jobs and run a specific other wcg CPU project (only it)? I can't find it. The workaround doesn't work so good, so I'm asking. |

Are there a different amount of work units for AMD and NVIDIA in the pipeline? It seems like most people are using NVIDIA cards. I am thinking of getting a new GPU and i wonder what will be the most beneficial if work units are limited. thanks

There is no "workaround". You can't set your profile to ignore OPN1 CPU tasks and get CPU tasks from another project while getting OPNG tasks only using the same profile. Only way is to micro manage it. Use a different profile to get the CPU tasks you want. When you have enough switch pack to the OPNG profile and wait for tasks. When you get low on the other CPU tasks switch back and download some more then go back to your OPNG profile and wait.

Apparently it requires some high-level discussion and re-configuring at WCG. I haven't heard back about it since. It is an obvious thing to want, but as long as they have enough GPUs to support the project, I doubt they will make it a high priority. |

During the initial release of the application, all devices are claimed as unreliable and need to be compared with a wingman. So, if a wingman is required, it gets put on the feeder with a required app version that prevents all other classes from getting it. Usually we have a mixture of results that need a specific class and others that are completely open. Thanks, -Uplinger |

... it gets put on the feeder with a required app version that prevents all other classes from getting it ... I'm a little nervous about that methodology. If there's a subtle but generic fault in one particular variant (and I wrote to you about one such possible case on Monday), 'confirmation bias' will lead to other machines of the same class validating the WU and disguising the error.SETI@Home chose, from the very beginning, to encourage users to build apps from the open sources to run on their particular obscure operating system or hardware. Those tasks were required to take their place in the rough-and-tumble of validation against any other variant of the science application, whether project-built or self-built. Some subtle (but minor) errors were picked up that way. |

Some subtle (but minor) errors were picked up that way. Hey Richard, I did not get a chance to write back about this kind of issue, but we have additional validation that is done on the backend that is not a bitwise comparison as it sounds like SETI was initially using. We worked with the scientist to come up with a way to validate results that are sent back to us that can use but don't require a wingman for validation. We also spot check all 'reliable' hosts and can mark them as unreliable when they don't pass a single validation. All of this was discussed with the researchers at length and took months to get the validator to where it is now. They also have additional checks on their end during the post analysis. Thanks, -Uplinger |

No, SETI was not using bitwise validation. Each task returned up to 30 signal candidates: the number/type of signals reported had to match exactly, and for each signal candidate I think four (possibly more for some signal types) mathematical values had to match within a given tolerance. But having drawn your attention to the possibility of a problem, I'll leave it there. We can return to it when you start on v2.0, if you want.
