1) Message boards : Number crunching : OpenIFS tasks : make sure boinc client option 'Leave non-GPU tasks in memory' is selected! (Message 67633) Posted 13 Jan 2023 by ktf Post: Hi all, I have a 4-core CPU with 8GB of memory, no swap file. BOINC regularly crashes when it chooses to run 3 or more OpenIFS tasks concurrently. Is there any way to instruct BOINC never to run more than one Climateprediction task concurrently, even if other projects have no work available? I'd like to run a little Climateprediction alongside other projects, but I can't seem to find a way to make this work.
2) Message boards : Number crunching : Like ghost work unit (Message 51390) Posted 10 Feb 2015 by ktf Post: Okay, if it poses no problem for the science I'm fine with it :)
3) Message boards : Number crunching : Like ghost work unit (Message 51388) Posted 10 Feb 2015 by ktf Post: I have got the same problem: I have three WUs that show up here, but do not show up on my computer. http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=17725337 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=17725346 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=17760457 I think it is a good idea to 'free these' in some way, because I have no way to finish these, it is only going to slow down the final outcome this way :) Luckily, this computer hasn't been offline in the meantime, so I've captured the error messages. Maybe they can be of some use? 332: 12-Jan-2015 06:18:16 (low) [climateprediction.net] Sending scheduler request: To fetch work. 333: 12-Jan-2015 06:18:16 (low) [climateprediction.net] Requesting new tasks for CPU 334: 12-Jan-2015 06:18:19 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 335: 12-Jan-2015 06:18:19 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 336: 12-Jan-2015 06:18:19 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 337: 12-Jan-2015 06:18:19 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 338: 12-Jan-2015 06:18:19 (low) [climateprediction.net] Scheduler request completed: got 1 new tasks 339: 12-Jan-2015 06:18:19 (low) [climateprediction.net] No work can be sent for the applications you have selected 340: 12-Jan-2015 06:18:19 (low) [climateprediction.net] No work is available for UK Met Office Coupled Model Full Resolution Ocean 341: 12-Jan-2015 06:18:19 (low) [climateprediction.net] Your preferences allow work from applications other than those selected 342: 12-Jan-2015 06:18:19 (low) [climateprediction.net] Sending work from other applications 343: 12-Jan-2015 06:18:19 (internal error) [climateprediction.net] [error] State file error: missing file 344: 12-Jan-2015 06:18:19 (internal error) [climateprediction.net] [error] Can't handle task hadam3p_eu_zfk5_2013_0_009400872_2 in scheduler reply 345: 12-Jan-2015 07:18:55 (low) [climateprediction.net] Sending scheduler request: To fetch work. 346: 12-Jan-2015 07:18:55 (low) [climateprediction.net] Requesting new tasks for CPU 347: 12-Jan-2015 07:18:58 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 348: 12-Jan-2015 07:18:58 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 349: 12-Jan-2015 07:18:58 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 350: 12-Jan-2015 07:18:58 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 351: 12-Jan-2015 07:18:58 (low) [climateprediction.net] Scheduler request completed: got 1 new tasks 352: 12-Jan-2015 07:18:58 (low) [climateprediction.net] No work can be sent for the applications you have selected 353: 12-Jan-2015 07:18:58 (low) [climateprediction.net] No work is available for UK Met Office Coupled Model Full Resolution Ocean 354: 12-Jan-2015 07:18:58 (low) [climateprediction.net] Your preferences allow work from applications other than those selected 355: 12-Jan-2015 07:18:58 (low) [climateprediction.net] Sending work from other applications 356: 12-Jan-2015 07:18:58 (internal error) [climateprediction.net] [error] State file error: missing file 357: 12-Jan-2015 07:18:58 (internal error) [climateprediction.net] [error] Can't handle task hadam3p_eu_zfji_2013_0_009400849_1 in scheduler reply [...] 384: 12-Jan-2015 17:57:32 (low) [climateprediction.net] Sending scheduler request: To fetch work. 385: 12-Jan-2015 17:57:32 (low) [climateprediction.net] Requesting new tasks for CPU 386: 12-Jan-2015 17:57:35 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 387: 12-Jan-2015 17:57:35 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 388: 12-Jan-2015 17:57:35 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 389: 12-Jan-2015 17:57:35 (internal error) [climateprediction.net] [error] Can't parse file info in scheduler reply: file name is empty or has '..' 390: 12-Jan-2015 17:57:35 (low) [climateprediction.net] Scheduler request completed: got 1 new tasks 391: 12-Jan-2015 17:57:35 (low) [climateprediction.net] No work can be sent for the applications you have selected 392: 12-Jan-2015 17:57:35 (low) [climateprediction.net] No work is available for UK Met Office Coupled Model Full Resolution Ocean 393: 12-Jan-2015 17:57:35 (low) [climateprediction.net] Your preferences allow work from applications other than those selected 394: 12-Jan-2015 17:57:35 (low) [climateprediction.net] Sending work from other applications 395: 12-Jan-2015 17:57:35 (internal error) [climateprediction.net] [error] State file error: missing file 396: 12-Jan-2015 17:57:35 (internal error) [climateprediction.net] [error] Can't handle task hadam3p_eu_zvyg_2013_0_009435278_0 in scheduler reply

6) Message boards : Number crunching : Too many total results? (Message 35576) Posted 22 Nov 2008 by ktf Post: Hello, I just got my first WU from Climateprediction.net, this one: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=6253730 There are two peers with Compute Error, and I\'ve just spend 3 hours, with another 1300 to go. The WU page says: max # of error/total/success tasks 3, 4, 1 errors Too many total results Should I abort this task, or do I get that credit anyway?
