I've been running SETI since the `90's and this is the first time that SETI will not use all 4 of my CPU's. I have a quad system and a compatible graphics card. Usually I see 4 tasks running, one on each core, and another task running, if available, on my graphics GPU. I have not changed what is typically running on my system and I run it 24/7. If I run another app, such as Rosetta or World Community Grid, all 4 CPUs are used. Any thoughts would be appreciated. Extraordinary claims require Extraordinary proof. |

If you're running multiple projects, BOINC could be trying to balance your resource share allocations. If you're only running SETI, be sure your preferences are set to "on multiprocessor systems, use" 100% "of the processors". Note this setting MIGHT slow down your GPU processing. |

I just noticed that one of my SETI work units is running on my GPU but none are running on any of my CPU's. In an earlier post, I was told there are discrete CPU and GPU work units so I suspect I may just have a bunch of GPU work units downloaded and waiting to run and no CPU work units. How can you tell if a work unit is for the CPU or for the GPU? Thanks again. Extraordinary claims require Extraordinary proof. |

How can you tell if a work unit is for the CPU or for the GPU? Look in Application column (Sort by it and of course resize it to see all the text): http://setiathome.berkeley.edu/forum_thread.php?id=64710&postid=1124286#1124286 Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

All that tells me is which project the work unit is from, I understand that and I can see that. Both the CPU and GPU projects that I'm speaking about are from SETI. I want to know which is for the CPU and which is for the GPU. Extraordinary claims require Extraordinary proof. |

I want to know which is for the CPU and which is for the GPU. Advanced View, Tasks tab, Application column. CPU=6.03, GPU=6.09 or 6.10 depending on GPU type. |

It helps if you know that your GPU is CUDA capable. Thus the applications showing (cuda_fermi) will run on your GPU. |

All that tells me is which project the work unit is from, ... It shows the Application name, not the project (it is coincidence that sometimes the Application name contains the name of the project but not always) Similar Application names are shown on the web: the Application names "SETI@home Enhanced v6.10 (cuda_fermi)" and "SETI@home Enhanced v6.03": http://setiathome.berkeley.edu/results.php?hostid=6856975&offset=0&show_names=0&state=0&appid=2 the Application names "AstroPulse v6 v6.04 (opencl_nvidia_100)", "AstroPulse v6 v6.04 (cuda_opencl_100)", "AstroPulse v6 v6.01" (all from SETI@home but do not contain the name of the project): http://setiathome.berkeley.edu/results.php?hostid=6856975&offset=0&show_names=0&state=0&appid=12 Example from another project: on Asteroids@home http://asteroidsathome.net/boinc/ the Application name is "Period Search Application v100.00": http://asteroidsathome.net/boinc/results.php?hostid=110 Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

I see the cuda_fermi, so that answers that, all the tasks that I have in my queue are cuda_fermi. Thanks for the help. Extraordinary claims require Extraordinary proof. |

Got similiar problems with BOINC (SETI) running at Intel I7-520 (8 virtual CPU Cores, 4 physically cores), 6 GB RAM (2GB in 3 Banks, fast Triple-Mode), OS: Windows 7 64 Bit OEM-Version fr. Microsoft. I was setting up all conditions in boinc|assist|options to maximum Ressource-Usage (GPU and CPU using while working, 100 Percent on all). Observed via Windows Task Manager my System needed up 2 Minutes to reach maximum count of core-using and 100 percent cpu-using. Why this takes so much time? A little bit more "aggressive" behaviour of Boing Client vs. Windows would be nice. |

There is a lot of discussion, and help, on these problems in the Number Crunching part of the forum (http://setiathome.berkeley.edu/forum_forum.php?id=10). I suggest you head over there and have a read around. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |
