I dont waste ressources for projects i dont believe in. Not even the AIDS and Cancer Research at World Community Grid? |

Of course with hosts like this one (882 invalid/1413 inconclusive) work will be available for some time more. ;-) |

For me it's Einstein for GPUs and Cosmology for CPUs. Both have had a big increase in time over the last month anyway as I only crunch AP for SETI on all but my least powerful GPU. My GTX460 ran dry a while ago and is already significantly increasing my Einstein rank and I am also heading up the Cosmology rankings and may even make it into the UK top 10 in terms of total credit. All three of my machines have SETI as their preferred project, so as soon as work becomes available they will start eating it again. In the meantime, a change is as good as a rest as they say. |

I did warm up and start some back-up projects, such as Einstein. PrimeGrid, GPUGrid and made some (few) tests. I have always been a very SETI loyal cruncher, with very few escapes to other projects and that only some years ago when I had rather low power graphic cards and much less experience. In case it were still necessary to point this out, I found in just one day (it did not take long time to assess this, due to the embarrassing extent of the problem) that the reward for crunching by these other projects goes from much higher to obscenely higher respect to SETI. I have even measured 1:20 ratios. We all know this issue and I do not want to rise this debate here. Only, I want to point out that many people like me, who are now in forced leave from SETI will discover this with real data and solid evidence as I am writing. In few days it will not just be reports or word of mouth, but personal experience for many. Cheers! Sleepy |

This drought has made me decide to look into other projects, for the first time. I tried out World Community Grid, until I realized that they currently don't have any GPU work. So now I am trying out Einstein. I'm finding that the work units are much larger than the ones for Seti. My GPUs that could do a MB in about 25 minutes are taking 5 hours or so over at Einstein. Sound about right to everyone? |

If that is on your GTX650 then it is probably good if you are running 3 at a time. My GTX660 takes 4 1/3 hrs 3 at a time running BRPs, BRP4s are much shorter. |

It is only running one at a time, but that likely means the GPU is being under utilized. I assume there is a similar appconfig file for E@H like there is for S@H? I guess this isn't the right place to discuss it, but the E@H forums look a little dead! |

They haven't adapted their code for newer GPUs in sometime from what I've read. There is also the difference in that they utilize the PCIe speed more when compared to Seti where PCIe speed isn't as important as GPU speed. If you do decide to do more than 1 work unit per GPU, make sure you run all the same kind. Mixing of different work types is counter productive to your RAC. |

Yes, 3 Perseus on each GPU run somewhere around 6-7 hours depending on GPU 3 Arecibo on each GPU run around 2-4 hours. I have different machines that run either 1 or the other. I don't run any work on the CPUs but that is up to you. |

I guess this isn't the right place to discuss it, but the E@H forums look a little dead! I'm afraid that there are few if any projects with the active participation you find in SETI forums. I doubt anyone would object if you started a dedicated E&H thread as long as it wasn't to bash the project. Boinc V7.2.42 Win7 i5 3.33G 4GB, GTX470 |

Yes, Now if someone could tell me, with my version of BOINC, how to do 2 GPU tasks at 1 time I maybe interested just to see what happens while I'm back there for backup needs just as a personal experiment. ;-) Cheers. |

It's a little different over there, Wiggo. The easiest and sanctioned way to go to "your account" and then select "Einstein@Home preferences" and I think you'll find it self-explanatory after you figure-out which program does what. |

Doh! Maybe I should stop being lazy at time and checked for any changes there to start with. gives self a face slap Thanks tbret. Cheers. |

OK, I must be stupid, nothing there did anything. :-O [edit] Likely has something to do with the BOINC version that I'm running. Cheers. |

No, you aren't stupid. I just didn't go far enough. You have to change those settings and save them. Then you have to wait until the computers connect to the servers. Then the servers see the changes. None of the settings will have any effect until the next time the project *downloads work.* I know... it's annoying at best because you can't immediately tell if what you just did had the desired effect. I know, I know... but that's the way it works. |

So do I just change those 3 apps to 0.5, 2 or -1 (it's not really that plain if you have no idea. :-) Cheers. |
