(Message 1825) Posted 24 days ago by Matthias Lehmkuhl Post: I again had a really long running (never ending??) gnfs-lasieve... process with 246:47:05 hours (I aborted it today) all other gnfs-lasieve... checks last round 470 seconds for this task I've seen this "problem" process and wanted to give it a try, but it looks like to no success. https://yafu.myfirewall.org/yafu/result.php?resultid=9373608 This package 7964375 Aliquot Sequence 3134712 has already 2 not finished tasks before I got my task https://yafu.myfirewall.org/yafu/workunit.php?wuid=7964375 only a few task have this behaviour on this machine and I had this issue also with older Boinc versions
2) Message boards : Number crunching : When should a "stalled" task be aborted? (Message 1779) Posted 11 Jun 2024 by Matthias Lehmkuhl Post: Hello, I've again a long running gnfs-lasieve4l3e thread with now over 24 hours CPU runtime (LatSieveTime) the other threads have not more than 750 seconds LatSieveTime for this task And other threads are not started till this thread is finished 06/09/24 08:55:28 v1.34.5 @ MA64-003, nfs: commencing lattice sieving with 4 threads the 3 other threads are finished since 06/09/2024 09:04 for me it looks like the thread has "wrong" parameters that can not finish Task with this behaviour https://yafu.myfirewall.org/yafu/result.php?resultid=8928821
3) Message boards : Number crunching : Wrong Core Parameter on 8t WUs? (Message 1624) Posted 5 Jun 2022 by Matthias Lehmkuhl Post: For me the 10 additional days did work on my 8t task with 1 core running. The result finished yesterday in the additional time and no new sending of a result for this package was necessary.
4) Message boards : Number crunching : Wrong Core Parameter on 8t WUs? (Message 1610) Posted 31 May 2022 by Matthias Lehmkuhl Post: I found the command line for this result "yafu.exe" -threads 1 -batchfile in The previous task on this machine was running normal with 8 cores based on stderr.txt from older result of this machine 12:27:39 (15320): wrapper: running yafu.exe (-threads 8 -batchfile in) https://yafu.myfirewall.org/yafu/result.php?resultid=8015475 and I don't have a app_info.xml for yafu in the project folder
5) Message boards : Number crunching : Wrong Core Parameter on 8t WUs? (Message 1608) Posted 30 May 2022 by Matthias Lehmkuhl Post: Hello yoyo, yes, that is the normal way yafu 8t is running. But this result was running only one ecm or is now running only one gnfs process each time and the remaining 7 cores are used for tasks of other projects instead yafu 8t is claiming them. Boinc is running on 8 cores/cpus and this is the actual cpu usage of the boinc projects while my yafu 8t task is running looks like the image Tag is not working for me, so here also as link to OneDrive https://1drv.ms/u/s!Apg6sr6l28yehnng4Pso4kpnDYpS?e=UGhl3g
6) Message boards : Number crunching : Wrong Core Parameter on 8t WUs? (Message 1606) Posted 29 May 2022 by Matthias Lehmkuhl Post: I got this WU which should run on 8 cores https://yafu.myfirewall.org/yafu/result.php?resultid=8012392 Projekt yafu Name yafu_ali_2136852_L134_C131_1652795706_2_2 Anwendung YAFU-8t 134.05 (8t) Arbeitspaketname yafu_ali_2136852_L134_C131_1652795706_2 Status Aktiv Erhalten 28.05.2022 09:59:02 Deadline 30.05.2022 19:53:32 ... Verzeichnis slots/4 but when I look at at the BoincTasks core usage I see only 1 core is used and the stderr.txt too tells that it's using only one thread 10:04:19 (14068): wrapper (7.5.26014): starting 10:04:19 (14068): wrapper: running yafu.exe (-threads 1 -batchfile in) And in Process Explorer to also saw only 1 process of ecm.exe was running while I checked it yesterday.

(Message 1457) Posted 25 Nov 2019 by Matthias Lehmkuhl Post: Hello, I too have a result that looks like running forever yafu_ali_2145600_L131_C124_1571470508_8_5 https://yafu.myfirewall.org/yafu/result.php?resultid=5325104 the result is running with one gnfs-lasieve4I13e.exe (one CPU) now at 114 hours The first result was started at 19.10.2019, an no result finished so far.
8) Message boards : Number crunching : Too many total results (Message 647) Posted 19 Mar 2014 by Matthias Lehmkuhl Post: I found a result marked as errors Too many total results http://yafu.dyndns.org/yafu/workunit.php?wuid=32617 Maybe it depends on the not meet deadline Report deadline 18 Mar 2014, 22:16:56 UTC Received 19 Mar 2014, 1:47:17 UTC And I got credit for my result. But it looks strange. The boinc client (7.2.42) did not start the result near the/after deadline automatically, the progress time was over. But the result wasn't finished. I'm using BoincTasks, so the view is a bit different. Edit: add Boinc Client Version

14) Message boards : News : C112 reached (Message 479) Posted 3 Aug 2012 by Matthias Lehmkuhl Post: It`s no problem for me when you use several cores for the project, but Yafu stops all GPU applications immediately. Sry, unacceptable. This problem is solved with boinc core client 7.0.31 "Ein Hinweis für Nutzer der neuesten BOINC-Versionen (7.0.2x): Aufgrund eines BOINC-Bugs ist es nicht möglich, gleichzeitig Multithread-WUs (z.B. eben YAFU) und GPU-WUs anderer Projekte laufen zu lassen. Sobald in diesen BOINC-Versionen eine Multithread-WU gestartet wird, werden sämtliche GPU-WUs angehalten. Das Problem ist in BOINC 7.0.31 behoben." from Seti-Germany forum http://www.seti-germany.de/forum/das-hauptforum/6331-teamwork-2012-gemeinsam-bewegen-speg-2nd-wave-bei-yafu.html#post221955
