Hi, Anyone who know why my SETI crunching numbers are low comparred to other projects? Yes, I can just change the percentage of the priority, but even that may not solve the issue!? The percentage for my 3 projects are 33.3% each. Einstein@ and Asteroid@ are running like crazy, while my SETI jobs are moving forward a job or two a week. I noticed that when running asteroid jobs, GPU's temperature which I log accordingly, seems a great deal higher than e.g. SETI temp's. And I seem to recall a conversation I had with someone inhere last year. Anyway, this only confirms my issue but doesn't solve it. I would be gratefull if someone had a fix... Running multiple GPU's and a single CPU on several Linux systems. Distro is Ubuntu 14.04.x These are the 2 types of systems running: BOINCversion: 7.2.42 Linux3.16.0-30-generic, Linux3.13.0-32-generic [4] NVIDIA GeForce GTX 750 (2047MB) OpenCL: 1.1 GenuineIntelIntel(R) Core(TM) i5-4670K CPU @ 3.40GHz [Family 6 Model 60 Stepping 3](4 processors) BOINCversion: 7.2.42 Linux3.13.0-32-generic [4] NVIDIA GeForce GT 640 (1023MB) OpenCL: 1.1 GenuineIntelIntel(R) Core(TM) i5-4690K CPU @ 3.50GHz [Family 6 Model 60 Stepping 3](4 processors) https://boincstats.com/signature/-1/user/2560253/sig.png Kind Regards Dan Hansen Project Headless CLI Linux Multiple GPU Boinc Servers Ubuntu Server 14.04.1 64bit Kernel 3.13.0-32-generic CPU's i5-4690K GPU's GT640/GTX750TI Nvidia v.340.29 BOINC v.7.2.42 |

You didn’t say what app you are running. I would guess it’s the project supplied ones. If so you might want to run the cuda80 one, but you would need an up to date Nvidia driver installed (to get CUDA 8 support). There is a rather long thread about running it here BOINC blog |

Yes CUDA80 would definitely improve your runtimes, my 750Ti's don't go over 13 minutes per task, at the most. But I see that your computers are not processing the tasks you have on hand, as you said it has to do with Resource Shares between projects. It could be your computer is over-committed with other projects, thus it is trying to run those tasks off first. Einstein has been said to be bad for that - not playing nice with others. |

Regardless of which seti application you are using the short deadlines of your other projects will tend to mean seti willinitially lag behind. Over time (weeks/months) things will even out.
