1) Questions and Answers : Bugs : Abortet: Runtime exceeded (Message 704) Posted 29 May 2023 by crashtech Post: I hope this gets fixed, until then I am not going to run LODA anymore.
2) Questions and Answers : Bugs : Abortet: Runtime exceeded (Message 701) Posted 28 May 2023 by crashtech Post: I just got a some of these on two of my hosts, 6659 and 6653: 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED Examples: https://boinc.loda-lang.org/loda/result.php?resultid=6375446 https://boinc.loda-lang.org/loda/result.php?resultid=6369522
3) Message boards : News : Checkpoints enabled (Message 277) Posted 24 May 2022 by crashtech Post: We have published the new app version 220523. It includes several fixes for networking issues and adds checkpoint support. This allows you to resume your computations after restarts. Thank you for adding checkpointing, it's much appreciated.
4) Questions and Answers : Bugs : All errors (PLEASE OPEN NEW THREADS) (Message 258) Posted 22 May 2022 by crashtech Post: The error is EXIT_TIME_LIMIT_EXCEEDED. The execution time is actually below the limit of 5h. My guess would be: the task was resumed after some break and BOINC counts the entire execution time. We don't have checkpoints yet, but we will add it soon (in the next appversion). I would assume that this will fix the problem. Thank you for your reply. I found it interesting that the time limit exceeded error shows in the stderr_txt, but wasn't reported in the log . I don't believe the tasks that were running on this host were interrupted, at least not manually, but it is possible they were suspended by BOINC due to low memory. I may try running much fewer tasks for a while on that host to see if that helps.
5) Questions and Answers : Bugs : All errors (PLEASE OPEN NEW THREADS) (Message 246) Posted 21 May 2022 by crashtech Post: @[TA]crashtech: did you find errors in your logs? https://boinc.loda-lang.org/loda/logs.php There are errors, but interestingly, the log entries for the failed tasks don't have obvious errors. Here is an example: Task 131371: https://boinc.loda-lang.org/loda/result.php?resultid=131371 The corresponding log, as far as I can determine: wu_1653078494_2121_0_r1319145355_0 2022-05-20 16:35:59\|INFO \|Starting LODA v22.5.20.

6) Questions and Answers : Bugs : All errors (PLEASE OPEN NEW THREADS) (Message 235) Posted 21 May 2022 by crashtech Post: I am getting a lot of these on one particular host, it's not overclocked, running an Ubuntu VM inside Windows 10. Another almost identically configured machine is not getting the errors: <core_client_version>7.16.6</core_client_version> <![CDATA[ <message> exceeded elapsed time limit 10986.99 (86400.00G/7.86G)</message> <stderr_txt> 16:06:22 (24065): wrapper (7.5.26014): starting 16:06:22 (24065): wrapper: running ../../projects/boinc.loda-lang.org_loda/loda-220520-linux-x86 (boinc -H 4) </stderr_txt> ]]> I think I am going to stop running it on this on machine for now, until the cause is figured out.
7) Questions and Answers : Bugs : Are there checkpoints? (Message 232) Posted 21 May 2022 by crashtech Post: In my experience, lack of checkpointing can deter users from participating. I also tend to think that implementing checkpoints shows best regard for volunteer's time and resources. These are just my opinions. I will participate for a while, but as a cruncher who has several computers, I get discouraged when, say a power outage causes several hundred hours of computing to be lost. This has happened to me in the past. It may seem trivial to some, but more important to others. Most mature projects have checkpointing. I do not know how they implement it in a tamper-proof way. If it can't be implemented in LODA, then perhaps shorter task durations would mitigate the loss to volunteers caused by unscheduled reboots.
8) Questions and Answers : Getting started : New version available for better problem analysis (Message 213) Posted 20 May 2022 by crashtech Post: Another option for Windows 10 users is WSL2. LODA runs perfectly in an Ubuntu VM running within Windows. https://docs.microsoft.com/en-us/windows/wsl/install
