1) Message boards : Number crunching : Batch 1008, and test batches 1009 to 1014 for Windows - issues (Message 70701) Posted 15 days ago by Harri Liljeroos Post: I'm seeing the same, here: https://www.cpdn.org/result.php?resultid=22415908 and here: https://www.cpdn.org/result.php?resultid=22417236
2) Questions and Answers : Windows : Question about my unit. (Message 70647) Posted 12 Mar 2024 by Harri Liljeroos Post: I don't know about the specific set (eas25 1004) but the average run time for wah2 models according to server status page is 2.11 weeks.
3) Message boards : Number crunching : Recent Average Credit. Correct for user, zero for computers. (Message 69959) Posted 20 Oct 2023 by Harri Liljeroos Post: I see now some accumulated RAC on my Hosts page. Numbers are small and do not correspond to the user RAC. But maybe they'll catch up.
4) Message boards : Number crunching : Recent Average Credit. Correct for user, zero for computers. (Message 69871) Posted 15 Oct 2023 by Harri Liljeroos Post: Here's what one of my hosts has accumulated. This is a bit easier to see as it is running only one CPDN task: https://www.cpdn.org/result.php?resultid=22339724 It has sent 20 trickles (2 every day) and has accumulated 16,588.11 credits which gives 829.4055 credits/trickle. So Boinstats should see as credit/day a multiple of that value. But the value in Boincstats is all over the place. So either credit/trickle is not constant or it is calculated incorrectly or reported incorrectly. From Boincstats: Date Total Credit Credit/day 2023-10-15 4,346,979 955 2023-10-14 4,346,024 657 2023-10-13 4,345,367 359 2023-10-12 4,345,008 73 2023-10-11 4,344,935 235 2023-10-10 4,344,700 534 2023-10-09 4,344,166 832 2023-10-08 4,343,334 1,129 2023-10-07 4,342,205 1,428 2023-10-06 4,340,777 849 2023-10-05 4,339,928 0 From this site: Time Sent (UTC) HostID ResultID Result Name TimeStep CPU Time sec/TS 15 Oct 2023 14:57:02 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 230,699 831,693 3.6051 15 Oct 2023 03:25:37 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 219,179 790,837 3.6082 14 Oct 2023 15:57:04 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 207,659 750,083 3.6121 14 Oct 2023 04:21:22 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 196,139 708,991 3.6147 13 Oct 2023 17:01:57 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 184,619 668,864 3.6229 13 Oct 2023 05:50:50 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 173,099 629,080 3.6342 12 Oct 2023 18:44:10 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 161,579 589,611 3.6491 12 Oct 2023 07:23:50 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 150,059 549,678 3.6631 11 Oct 2023 20:11:48 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 138,539 509,836 3.6801 11 Oct 2023 07:50:01 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 127,019 469,245 3.6943 10 Oct 2023 19:56:52 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 115,499 426,910 3.6962 10 Oct 2023 07:46:33 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 103,979 383,865 3.6918 09 Oct 2023 19:39:39 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 92,459 340,791 3.6859 09 Oct 2023 07:29:41 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 80,939 297,613 3.6770 08 Oct 2023 19:18:01 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 69,419 254,183 3.6616 08 Oct 2023 07:14:23 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 57,899 211,254 3.6487 07 Oct 2023 19:12:16 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 46,379 168,406 3.6311 07 Oct 2023 05:50:50 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 34,859 126,354 3.6247 06 Oct 2023 18:05:17 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 23,339 84,502 3.6206 06 Oct 2023 06:09:30 1286606 22339724 wah2_eas25_a2vc_200312_24_996_012227268_0 11,819 42,742 3.6164
5) Message boards : Number crunching : Batch 996 Weather@Home2 East Asia25 (Message 69769) Posted 11 Oct 2023 by Harri Liljeroos Post: I've experienced an unexpected power failure today. My two hosts were both running an EAS task while this happened. Both seem to have survived the abnormal shutdown and are now crunching ahead. The win10 host task survived also the patch Tuesday restart earlier this morning.
6) Message boards : Number crunching : Credit handed out weekly? (Message 69586) Posted 5 Sep 2023 by Harri Liljeroos Post: The page on web site that shows my computers is still showing 0 for average credit on all computers. This means that Boinc manager is also showing 0 RAC for them.
7) Message boards : Number crunching : Credit Question Answered (Message 69348) Posted 17 Jul 2023 by Harri Liljeroos Post: Client side credit calculation would open the possibility for cheating as the program is open source and users can compile their own versions.
8) Questions and Answers : Windows : Upload issue. (Message 69317) Posted 14 Jul 2023 by Harri Liljeroos Post: Something else you might want to mention to Andy, concerns my displeasure with the way tasks have been sent. This is a four core eight thread machine, so it downloaded eight work units. These jobs take sixteen to seventeen days to run, and BOINC has stopped work from all my other projects to run them.This, obviously, includes GPU work. I have suspended six of these new tasks and will release them one at a time as jobs finish, (and presumably get stuck like the first one...). I shouldn't have to micromanage this. There is on the web site project preferences possibility to set how many tasks you receive from CPDN. Possible selections are 1...8 and 'no limit' (This may be a new option, I don't remember seeing it before on CPDN), I think that 'no limit' is the default.
9) Message boards : Number crunching : New work discussion - 2 (Message 69122) Posted 6 Jul 2023 by Harri Liljeroos Post: I hope that they allow the currently running work to finish. I have 3 tasks running and they need 2-5 days before they are completed.
10) Message boards : Number crunching : Why does this task fail ? (Message 67492) Posted 10 Jan 2023 by Harri Liljeroos Post: The output files are absent because the tasks failed and crashed. So the output files were never created. So that is outcome from crashing not the cause of it.
11) Message boards : Number crunching : OpenIFS tasks : make sure boinc client option 'Leave non-GPU tasks in memory' is selected! (Message 67281) Posted 4 Jan 2023 by Harri Liljeroos Post: And user can always select to use local preferences that will override web site preferences.
12) Message boards : Number crunching : If you have used VirtualBox for BOINC and have had issues, please can you share these? (Message 67229) Posted 2 Jan 2023 by Harri Liljeroos Post: I have a few observations from the LHC about running VB tasks: 1. Boinc (or Boinc Manager) that is running in the host OS does not know about the memory usage of an VB task, it relies only to the memory_rsc_bounds value that is set up for a task. So actual memory consumption monitoring needs to be done inside the VB. Windows task manager doesn't know the actual memory consumption of the virtual machine either, Task Manager just sees that memory is used but does not know by which process (or at least won't show it to you). 2. The task's actual progress is also not reported back to Boinc Manager. Boinc Manager uses a simulated progress that it shows for the user but it is wildly inaccurate at best of times and downright bogus sometimes. If user wants to see the actual progress, that has to be built into the VB application like LHC's Atlas tasks have.
13) Message boards : Number crunching : If you have used VirtualBox for BOINC and have had issues, please can you share these? (Message 67222) Posted 2 Jan 2023 by Harri Liljeroos Post: I think that we need to remember that there are two ways to run VirtualBox environment with Boinc. 1. Create your own virtual computer and install Linux or some other OS on it. Then install Boinc and attach to CPDN and/or some other project. 2. Use project made virtual machine file that is run automatically by Boinc in host os (Windows, Linus etc.). Project defines what kind of CPU virtual environment is emulating, what OS to use and allocates necessary resources for it (CPU cores, memory, disk size etc.). This is how LHC is using the VirtualBox for Atlas, CMS and Theory tasks in Windows. I think that the number 2 is the way CPDN is thinking of doing it?
14) Message boards : Number crunching : OpenIFS tasks : make sure boinc client option 'Leave non-GPU tasks in memory' is selected! (Message 67160) Posted 30 Dec 2022 by Harri Liljeroos Post: Modifying the file might be possible but you would need to restart Boinc for it to take effect.
15) Message boards : Number crunching : Missing Trickle (Message 65840) Posted 15 Aug 2022 by Harri Liljeroos Post: The trickles are back for wah2 nz25 tasks on the tasks pages!
16) Message boards : Number crunching : Missing Trickle (Message 65837) Posted 14 Aug 2022 by Harri Liljeroos Post: The trickles from the new wah2 nz25 tasks are not visible on the server task pages but the credit has been awarded for them anyhow.
17) Message boards : Number crunching : NZ25 file upload server problems? (Message 65826) Posted 13 Aug 2022 by Harri Liljeroos Post: All of my uploads have gone thru, but the web site is missing all the trickles. The trickles were there on Thursday evening.
18) Questions and Answers : Preferences : No New Work (Message 65333) Posted 8 Apr 2022 by Harri Liljeroos Post: And from the Applications page you can see what platforms are available to different task types.
19) Questions and Answers : Getting started : How to read server status? (Message 65287) Posted 14 Mar 2022 by Harri Liljeroos Post: I agree completely to your concerns and I would like to see those problems tackled soon. But there might be a reason for the lack of development here. The climate change has been a lot on the news recent years and policy makers may see this area of science more 'sexy' and vital for mankind. The scientific groups doing the research are nowadays maybe more likely to get funding for their research and therefore push their climate simulations to the super computer environment. This would probably give them results faster and without the hassle and uncertainties involved in CPDN environment. Just my 2 cents.
20) Questions and Answers : Windows : is climate prediction running? (Message 65000) Posted 24 Jan 2022 by Harri Liljeroos Post: I just download 7.16.20.0 x64 on win10 and have NOT gotten any work / updates. I assume it is still not offering anything? I go to update and it says communication deferred (1 hour). I have had this happen for possibly 24 hours now. Thank you! That's the way it is. Currently also the Linux and Mac systems are out of new work.
