Number crunching :
Host with WAY too many tasks.
(Message 45638)
Posted 851 days ago by Astromancer. So I was going through my WU's that were sitting around waiting for wingmen to report back and came across http://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=247482. At first I thought perhaps it was a bug and the tasks would go down as they timed out / were reported. But it went from having 74xx last night to 76xx when I just checked... So obviously something is wrong here. Not being sure what to do, I figured I'd post it here and someone else would know / a mod / project admin would see it or whatever. |

app_info - no n-body error...
(Message 45281)
Posted 877 days ago by Astromancer. Thanks Arkayn, That's what I started to think when I saw I'd sometimes get tasks on a request. I myself am doing Collatz as that's my backup project. @Werkstatt I have the CPU tasks turned off, but it seems that if there is only N-Body work I get that error no matter what. |

(Message 45272)
Posted 878 days ago by Astromancer. So I'm only running the GPU app and using an app_info to tweak how it runs. Now since about 7:30 I've been getting: Milkyway@home Message from server: No work sent Milkyway@home Message from server: Your app_info.xml file doesn't have a version of MilkyWay@Home N-Body Simulation. Is it that there is no work other than n-body work, or did the server just randomly decide not to like me? Thanks in advance! -TJ |

OpenCL for Nvidia available for testing
(Message 44761)
Posted 895 days ago by Astromancer. After I posted the last one I figured you would need more details since the deleter is deleting things right away. (Looks like I was right) So I went about getting them for you. One other thing I noticed on my system is that the OpenCL tasks sit at 100% with the clock still going for about 30s. I'll PM you with all the info so I don't make a huge post full of data useless to anyone but you and Travis. |

Posted 895 days ago by Astromancer. Matt, I downloaded the WU's all today and within about an hour of each other. I did 4 OpenCL then 3 CUDA before posting and another few CUDA after posting (With the same type of run time seen). The memory bandwith usage struck me as odd as well which is why I posted it. I was running GPU-z to watch what was going on a bit to make sure it wasn't say using 50% of the GPU core or something and noticed that the "Memory Controller Load" was reading at 50% or over. I've only ever seen that with SETI before. I'll give a try with 48.1 and see if anything different happens. If there is some kind of test WU I can run through the command line or the like to help you out any, I'd be more than willing to do it. |

Posted 895 days ago by Astromancer. With 48.0 I found that the runtimes are over 2m longer than with the CUDA app on my GTX260. 15:40 - 16:00 for OpenCL and 13:22 - 13:31 for CUDA. The memory bandwith used on the card is up to about 50% as well which is a HUGE jump from CUDA (0%). As well as having a larger system memory footprint. Just found that interesting, it doesn't particularly concern me. And it also uses more CPU time than the CUDA app, though I didn't notice the cpu being used while I was watching the task manager. Does it use most / all of the cycles at the start or end of the WU or something? |

Status: "Validate Error" and still getting credit?

Posted 910 days ago by Astromancer. One of my team members checked his and apparently all of his have validated. *shrug* Who knows. |

Status: "Validate Error" and still getting credit?
(Message 44029)
Posted 910 days ago by Astromancer. So I started crunching MW again today and looking through my tasks found a number of WU's that are marked "Validate Error" in the status but are still giving me full credit for doing them. Both of which I find odd as I never used to have any errors with validation. I didn't see any other posts about this so made a new one. Sorry if I missed something. EDIT:: To add it's happened with both ATI and nVidia units. 3870 and GTX260. CPU units are still running. EDIT2: Another unit was a Quorum: 2 unit and when I returned my result it canceled the 2nd result out there and gave me credit which also seems quite odd. |

GPU Stock App Vs. SSE2
(Message 42552)
Posted 959 days ago by Astromancer. Oh, I figured the stock app was the non SSE2 version that was up on your site for 32 bit. Didn't expect them to use the SSE2 as the default. More compatibility and whatnot. Thanks for the info Arkayn. |

Posted 959 days ago by Astromancer. Since I was out there I figured I'd just do it and see what happened. Turns out there is no difference on this machine at least. Kind of what I figured would happen. Figured I'd update this to perhaps help someone else out in the future that is doing a search for the info or whatever. |
