1) Message boards : Number crunching : New work Discussion (Message 62915) Posted 9 Nov 2020 by BetelgeuseFive Post: - When I first encountered this problem I thought it was related to 32-bit library issues, but I have doubts about this now. I recently switched from CentOS 7 to Ubuntu 18.04 LTS because some of the projects I am running were dynamically linked to newer libraries than provided with CentOS 7. In these cases I would get tasks, but they would error out because of the missing dynamic libraries. Does the CPDN server has any clues as to the dynamic libraries installed on my system ? I would think not as there are too many different versions for different Linux distributions, so my guess is that it would just send out work and it would error out because of the missing dynamic libraries. Don't know about CentOS but the instructions in the pinned post in the Linux section give instructions to install the libraries that are missing for most. If with any distro still getting problems with missing libraries, run ldd on the executable from CPDN and it will list anything missing. (I know from experience that it can then take a bit of detective work to find the package that supplies said library.) You are missing something here: Catch-22 If you get no tasks you also do not get the executable (you get it when the first task is assigned). It is very hard to run ldd on an executable you do not have. This is exactly the reason why I doubt the problem is caused by missing dynamic libraries: the CPDN server has no way of knowing if the correct libraries are present. If have seen this with several other projects: you get a task that errors out and in the error log you can usually see it was caused by missing dynamic libraries. You install the missing libraries (if they are provided by the distribution you are using !) and you check if the next task works. Tom
2) Message boards : Number crunching : New work Discussion (Message 62898) Posted 8 Nov 2020 by BetelgeuseFive Post: Betelgeuse. What are your settings for days of work to be stored? The N216 models can easily take 15 to 20 days to complete and if BOINC thinks that you haven't allowed enough time it might not get you any work. Also are you running any other work units from other projects? OK, I received a task now.. My settings were store at least 0.5 days of work with an additional 0.1 days of work. Set all other projects (I am running 12 projects at the moment) to no new tasks and changed settings to 1.5 + 1.5 days. First try after this I got a task. A couple notes/questions related to this: - I enabled some of the event log debug options. This resulted in a huge number of lines in the event log, but nothing useful. - Why does CPDN not issue work when I request it ? The settings say store at least a certain amount of work, there is nothing about a maximum. - When I first encountered this problem I thought it was related to 32-bit library issues, but I have doubts about this now. I recently switched from CentOS 7 to Ubuntu 18.04 LTS because some of the projects I am running were dynamically linked to newer libraries than provided with CentOS 7.

Thanks everybody for the help. Tom

See this post for commands to install the necessary libraries for common Linux distributions... https://www.cpdn.org/forum_thread.php?id=8916#62038 I installed the 32-bit libraries for Ubuntu 18.04 LTS: sudo apt-get install lib32ncurses5 lib32z1 lib32stdc++-6-dev Everything installed fine, but I am still not receiving new work (same message as before): Sat 07 Nov 2020 10:07:22 AM CET \| climateprediction.net \| update requested by user Sat 07 Nov 2020 10:07:25 AM CET \| climateprediction.net \| Sending scheduler request: Requested by user.

4) Message boards : Number crunching : New work Discussion (Message 62866) Posted 6 Nov 2020 by BetelgeuseFive Post: According to the server status page there are over 600 tasks available for UK Met Office HadAM4 at N216 resolution From what I understand these are Linux tasks, but I am not getting any work when requesting it from my Linux system. Are there any special requirements for these tasks that I am not aware of ? Thanks, Tom

6) Message boards : Number crunching : Stuck upload issue (Message 57785) Posted 17 Feb 2018 by BetelgeuseFive Post: I still have two stuck uploads from the following tasks: https://www.cpdn.org/cpdnboinc/result.php?resultid=20919737 https://www.cpdn.org/cpdnboinc/result.php?resultid=20919722 Both uploads are appr. 105 Mb in size. One of them is stuck at 53 Mb the other one at 46 Mb. As no one seems to be willing to look into this or tell us what to do about it I have set no new tasks for CPDN until this is resolved.

10) Message boards : Number crunching : HadCM3 short errors (Message 52007) Posted 30 May 2015 by BetelgeuseFive Post: Alan, While most of my "No Resubmission" tasks are the 1980s batch, a few are not, so it is necessary to check them all. I don't know if I am referring to the same problem here, but I recently had a number of tasks that failed with an 'out of memory' message. Same message reported by other tasks for the same workunit. Examples: http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9406431 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9413766 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9408774 The last one in this list was sent out again yesterday. Seems like a waste of resources ... Tom
