Just noticed this. Petri33's rig. 16 1080s? Just curious if he really has that many attached to his rig or if that is an anomaly in reporting. Meow? "Freedom is just Chaos, with better lighting." Alan Dean Foster |

His stderr reports 4 GPU`s. With each crime and every kindness we birth our future. |

LMAO You just noticed. It's been that way for months. That's his rewrite of the BOINC app to think it's got 4 times the number of GPUs to get 4 times the cache size. |

Could just run 4 clients... |

I think there is a problem with doing that on his systems. They have been trying to figure out how to run multiple clients from the command line in the "BOINC portable" for Windows hosts thread.

I think there is a problem with doing that on his systems. They have been trying to figure out how to run multiple clients from the command line in the "BOINC portable" for Windows hosts thread. Running multiple instances of BOINC at once and controlling them is rather straight forward. Currently I have a few hosts that run 100's of BOINC instances for goofygrid. As it only has NCI apps at this time. Having BOINC report more GPUs than exist in the system is also pretty easy & doesn't require modifying any code. Just tweaking some configs.

I think there is a problem with doing that on his systems. They have been trying to figure out how to run multiple clients from the command line in the "BOINC portable" for Windows hosts thread. As mentioned, its not that hard. I even put a guide on my home forum on how to setup multiple clients Windows and Linux. BOINCTasks and WUProp setup included.

Or an edit of how BOINC reads the hardware is more like it. |

The later one is correct. BOINC reads hardware and replaces the 1080 Ti with 1080 Tu and multiplies the count by four. When issuing tasks to GPUs it calculates bitwise (n & 3) to get GPU number 0-3. It runs one task at a time per GPU. Tu stands for Tuesday for obvious reasons.

Im surprised he only gets 180,398,646 credits. I saw 1080ti doing 60k with dual. |

That 180 million credits is since March 2015. the RAC for that beast is well over 300,000, so each of the GTX1080 are returning over 75,000 per day. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Petri is using a highly optimised application, a generation on from the one I am using that gives about 65,000 per day (per GTX1080), which in turn is a massive leap ahead from the SoG application that is the best stock application available under Windows.

Just noticed this. . . To be specific I believe it is 3 x 1080 and 1 x 1080ti :) Stephen :) |

I tried that when I found that out from the source code, however it did not work for me. That is why I had to make some modifications to the boinc client code and I wanted make it to be visible for everyone and that is why the Ti is called Tu. I'm still a week off.
