Constant Validation Inconclusive Results
(Message 76966)
Posted 19 days ago by mikey Post: Please SEND task 936827717 so task 935840769 can finally receive credit for the more than 10 (TEN) hours of CPU time run. They go at the end of the queue so if you look at the number of tasks to send out you can guess how long it will take, it's ALOT less than it was a month ago though!! |

Why is this project using all 8 cores when another project is trying to run
(Message 76964)
Posted 19 days ago by mikey Post: This project is using all eight available cores while another project is trying to run. Why is that? Because it's an MT app, meaning 'multi-threaded', it has an upper limit of 16 cpu cores but with an app_config.xml file you can change how many cpu cores each tasks uses. Of course the trade-off is each task will take longer to run but if you are okay with that then follow the link below or above depending on how you have this thread sorted. |

Posted 22 days ago by mikey Post: I am no longer getting tasks from milkyway, I also run asteroid and those are working fine. Increase your cache size, your other project probably has your cache already filled up so Boinc won't get more work as it doesn't think it will stay within your cache limits. |

Posted 27 days ago by mikey Post: I got the first of the de_nbody orbit_fitting tasks today. It seems like they will not follow the app_conf.xml. I have configured one of my "48 CPU" computers to run 4 tasks at a time using 12 CPUs each. All of the "old" nbody tasks obey this config file. But the 10 orbit_fitting tasks I got today are all listed as "Ready to start (16 CPUs) (none have run yet). Background, I have two identical computers. One has no app_config.xml file ( runs three tasks at a time using 16 CPUs ). The other has an app_config.xml file to run 4 tasks at a time using 12 CPUs. This has always worked. Even the plain ole nbody tasks I got AFTER the orbit_fitting tasks show "Ready to start (12 CPUs). Is this by design?[/img] Mine looks like this now and works for me: <app_config> <app_version> <app_name>milkyway_nbody</app_name> <plan_class>mt</plan_class> <avg_ncpus>2</avg_ncpus> <cmdline>--nthreads 2</cmdline> </app_version> <app_version> <app_name>milkyway_nbody_orbit_fitting</app_name> <plan_class>mt</plan_class> <avg_ncpus>2</avg_ncpus> <cmdline>--nthreads 2</cmdline> </app_version> <project_max_concurrent>1</project_max_concurrent> </app_config> You can see from mine that you have to add a new section with the new app name in it. I run mine with 2 cpu cores each and they just take longer to run but they run just fie so far, I'm waiting for my wingmen to know for sure of course. I am also only running 1 task at a time on my laptop, my desktops will have different settings based on the capability of each one. |

HIgh thread count applications
(Message 76912)
Posted 11 Feb 2024 by mikey Post: In another forum I read an article about applications with high thread counts are not as efficient. For example 16 thread count application will not finish twice as fast as an 8 thread count application. This got me thinking about how I might improving my throughput by running multiple applications at a lower thread count AND can I increase CPU utilization on some systems. One of my computers is a XEON E5 2678 with 24 "CPUs". Milkyway uses 16 by default but with a config file I can run two applications at a time with 12 CPUs apiece. Seems like a "no brainer". But how much did I gain? To "prove" that I would need 2 test files that had equal run times. First run sequentially, then run concurrently. Anyone here ever see any data like this? Pointers to other articles? Why not run some regular tasks one way and then some the other way, say for about 24 hours each, and then take the average times of each and see which is better. The problem with choosing just one task is that one task could be just that a one off and not representative of real life tasks except that one. IF you do want to run just one task you can run it outside of Boinc but I don't know how to do that. |

Posted 10 Feb 2024 by mikey Post: Because no one is leading the project. There is no IT department that deals with the project's server. It is not clear which hardware is used in the project's server. The computers you currently support for the project have much more advanced and high-tech hardware than the servers of this project. And now this project has started to lose its seriousness. Look, they haven't been able to solve a database problem for 2 weeks. Personally, if this problem is not solved within 1 week, I will withdraw my support from the project and turn to the universe@home project. Universe's main Scientist died recently and while they have a new one they are taking a break from sending out tasks for up to 3 months while they do things the way the new guy wants them done. But there's always Cosmology, as long as you are already have an account there, and Asteroids. |

Posted 9 Feb 2024 by mikey Post: Are completed N-Body tasks ever going to be validated? I now have over 100 completed tasks in my que, validation inconclusive. Should I quit crunching for this project? Yes they will be validated and no you shouldn't quit because that means they will take even longer to validate. The problem is the Server made a whole bunch of extra main tasks and when it makes a wingman task it goes at the end of the queue, so we are plowing thru all the main tasks before we start on all the wingman tasks. BTW I have 702 tasks waiting for a wingman. |

Posted 7 Feb 2024 by mikey Post: The Server Status page does not reflect correct numbers in the Work Status portion at the upper right when compared to the Tasks by Application at the lower left. Tasks Unsent vs Tasks Ready to Send One kink in that is you have to look at the Server version MW is using, I think they are an older version due to all the tweaks they have to make everytime a new version comes out. |

I used to get that at alot of projects but if I kept trying it would finally say 'ah I know who you are' and let things happen. What do you mean by your 'average workunits keep failing'? Are they going as 'inconclusive', are they going as 'invalid' or what? |

Posted 6 Feb 2024 by mikey Post: On February 5, Kevin Roux wrote (message 76876 in thread "Admin Updates"): That was initially designed at Seti so units that were waiting for a 3rd of 4th valid result would get it back more quickly than waiting thru the queue, IOW it got the tasks off the Server and into storage quicker because they would no longer be waiting for a valid result match. In the end they too turned it off because the ;faster; hosts, they initially tried to pick hosts that were returning tasks within 24 hours, were just pc's and like all pc's they too had the occasional problem and tasks weren't really coming back any sooner. |

Milkyway CPU usage reduced to zero, other processes after high cpu/ram usage
(Message 76852)
Posted 30 Jan 2024 by mikey Post: Hy This is the app_config.xml file I use: <app_config> <app_version> <app_name>milkyway_nbody</app_name> <plan_class>mt</plan_class> <avg_ncpus>2</avg_ncpus> <cmdline>--nthreads 2</cmdline> </app_version> <project_max_concurrent>2</project_max_concurrent> </app_config> What the file says is the nthreads 2 line means to only use 2 cpu cores per task and the max_concurrent line means only run 2 MilkyWay tasks at a time on the pc. I change the max_concurrent number based on the pc that I'm running MilkyWay on, ie my 32 core pc could say 15 to run 15 tasks using 2 cpu cores per task. You need to create it in Notepad, you can copy and paste it, for Windows and save it as a text type file in the folder c:\program data\boinc\projects\milkyway.cs.rpi.edu_milkyway Be sure the file is called app_config.xml and NOT app_config.xml.txt because then it won't work. After you have copied it to the right folder then go into the boinc manager and click the Options tab then read config files and it should start working. It won't control any existing tasks just tasks you get from that moment on. |

Milkyway CPU usage reduced to zero, other processes after high cpu/ram usage
(Message 76833)
Posted 29 Jan 2024 by mikey Post: The Milkyway project's CPU usage sometimes drops to zero and stays that way. Especially if there is little (free) memory in the machine. Or if a background application with a high CPU/RAM requirement starts. After that, Milkyway won't restart hours later, and BOINC client task switching doesn't work either. (I spent many, many hours looking at Resource Monitor and the Boinc client) How many cpu's does your pc have in it? It shows MW using 4 cpu's are you using an app_config.xml file to limit it? Also what do you have for the setting in the Boinc Manager under Options, computing preferences for 'when computer is in use' and 'when computer is not in use'. i use an app_config.xml file to limit each task to 2 cpu's and they just run non stop with no problems. I also have Boinc set to NOT suspend when pc is in use and to NOT stop when 'Boinc cpu usage is above'. i also unchecked the box to 'suspend when mouse or keyboard input in last ___ minutes'. In short on my pc's Boinc and MilkyWay runs 24/7/365, yes I also run other Projects at the same time, I limit the total number of tasks MW can run at one time in the same app_config.xml file. |

keep geting kicked off and not getting credits
(Message 76829)
Posted 28 Jan 2024 by mikey Post: I just restarted doing this project after taking a break from it. I got credit for about a week then kept getting zero credits a day. When I check Boinc the project keeps getting delisted from the projects I have going. I re-add it and it starts to run and the next day I have no credit and the project is off my project list again. Looking at my stats here it shows 225 work units "completed validation inclusive" These are all on n-body simulation units. How do I fix this? I'll start with your last question first...validation inconclusive is MilkyWay's way of saying you are waiting on your wingman to finish their task before you get your credits. They generated ALOT of tasks by accident a week ago and all wingman tasks go to the end of the list so give it another week or so and most/all of your tasks should start getting the credits they are owed. As for why it keeps getting delisted...are you adding the project manually or selecting it from the list in the Boinc Manager under Tools, add project? Because they went thru a couple of name changes and if you use the one on the list it's the new Official name. |

Posted 27 Jan 2024 by mikey Post: Thanks, I've set mine to also run multiple lower CPU count WUs. Is there any performance increase you see for doing this? No I do it because MilkyWay isn't my prime focus right now and I can adjust the tasks up and down easily and quickly depending on when my other projects have the tasks I want. |
