BOINC client version 7.2.42 I've installed the client according the Ubuntu-Installation guide(http://boinc.berkeley.edu/wiki/Installing_BOINC_on_Ubuntu "non-graphics installation") and got it running. Then I connected Boinc Bam! to my Odroid with the command boinccmd --join_acct_mgr http://bam.boincstats.com [myuser] [mypassword] This worked well and boinc downloaded the correct settings from Bam! and started to work on its first Einstein@Home task. The problem starts as soon as boinc finishes computing a task and connects to Einstein. I've noted that boinc client gets and uses the project settings from Einstein@Home (and stores it into /var/lib/boinc-client/global_prefs.xml) instead of the settings from Bam! I'm not very happy with that. How can I tell my client to use the config from Bam! and nothing else? Second question: is there a setting to influence how often the client connects to Bam!? Here's the "good" config from Bam! which I want to use (global_prefs.xml) <global_preferences> <host_specific/> <source_project>http://bam.boincstats.com/</source_project> <mod_time>1415659723</mod_time> <run_if_user_active>1</run_if_user_active> <run_gpu_if_user_active>1</run_gpu_if_user_active> <suspend_if_no_recent_input>0</suspend_if_no_recent_input> <cpu_scheduling_period_minutes>60</cpu_scheduling_period_minutes> <idle_time_to_run>3</idle_time_to_run> <work_buf_min_days>0</work_buf_min_days> <work_buf_additional_days>0</work_buf_additional_days> <max_cpus>2</max_cpus> <max_ncpus_pct>50</max_ncpus_pct> <suspend_cpu_usage>15</suspend_cpu_usage> <cpu_usage_limit>100</cpu_usage_limit> <disk_interval>30</disk_interval> <disk_max_used_gb>4</disk_max_used_gb> <disk_max_used_pct>50</disk_max_used_pct> <disk_min_free_gb>1.5</disk_min_free_gb> <vm_max_used_pct>75</vm_max_used_pct> <ram_max_used_busy_pct>40</ram_max_used_busy_pct> <ram_max_used_idle_pct>40</ram_max_used_idle_pct> <max_bytes_sec_down>0</max_bytes_sec_down> <max_bytes_sec_up>0</max_bytes_sec_up> <start_hour>19</start_hour> <end_hour>6</end_hour> <run_on_batteries/> <net_start_hour>0</net_start_hour> <net_end_hour>0</net_end_hour> </global_preferences> And here the "bad" config which appears automatically after the first upload to Einstein (global_prefs.xml) <global_preferences> <source_project>http://bam.boincstats.com/</source_project> <mod_time>1415659724</mod_time> <venue name="Home"> <ram_max_used_idle_pct>0</ram_max_used_idle_pct> <work_buf_min_days>0</work_buf_min_days> <cpu_usage_limit>100</cpu_usage_limit> <disk_min_free_gb>1.5</disk_min_free_gb> <end_hour>0</end_hour> <suspend_cpu_usage>0</suspend_cpu_usage> <disk_interval>60</disk_interval> <max_bytes_sec_up>0</max_bytes_sec_up> <max_bytes_sec_down>0</max_bytes_sec_down> <run_gpu_if_user_active>1</run_gpu_if_user_active> <ram_max_used_busy_pct>0</ram_max_used_busy_pct> <idle_time_to_run>3</idle_time_to_run> <start_hour>0</start_hour> <max_cpus>1</max_cpus> <disk_max_used_pct>50</disk_max_used_pct> <net_end_hour>0</net_end_hour> <net_start_hour>0</net_start_hour> <work_buf_additional_days>0</work_buf_additional_days> <cpu_scheduling_period_minutes>60</cpu_scheduling_period_minutes> <disk_max_used_gb>100.0</disk_max_used_gb> <hangup_if_dialed/> <suspend_if_no_recent_input>0</suspend_if_no_recent_input> <run_if_user_active>1</run_if_user_active> <max_ncpus_pct>100</max_ncpus_pct> <vm_max_used_pct>75</vm_max_used_pct> </venue> </global_preferences> Best wishes, Alex ID: 57602 ·

Last modified: 13 Nov 2014, 17:11:34 UTC Here's what I see: Both global_prefs.xml files show that BAM is the source project for the preferences, which would mean there's a problem with BAM its preferences being sent to the projects, or with how they're received by the projects. The global preferences are set in one location, these are read whenever your BOINC contacts the project, and sent to the other projects when BOINC contacts those, thus they propagate to all active projects you've got added to your BOINC. Seeing how the "bad config" has a newer mod time than the "good config" I can only assume it's a problem with BAM. bad: <mod_time>1415659724</mod_time> good: <mod_time>1415659723</mod_time> Seeing same examples at BAM forums, it would seem that this is some bug that's been long in the tooth at BAM. I'll ask the developers about if this is a BOINC problem, just to be safe. ID: 57610 ·

I am not a specialist in boinc software specs but I'm quite interested in it. Should Bam write its settings direct to the project preferences? It looks like the boinc-client takes the computing preferences "home" from Einstein@Home which are completely different to the settings in Bam. Additionally, I can't find any settings called "home" in Bam. I think boinc-client gives to the project settings a higher priority than to account manager settings. For me there is no reason why it behaves like that and if this makes any sense. Probably a bug... I'll set some preferences in Einstein for now to get my boinc running. Cheers, Alex ID: 57640 ·

Then, don't ask me why, the client puts a new (default-) config into global_prefs.xml which is not working for me ("don't compute while active"). I've looked into the folder /var/lib/boinc-client to see which files were changed at 22:34. Here's the list: account_einstein.phys.uwm.edu.xml client_state.xml and client_state_prev.xml daily_xfer_history.xml global_prefs.xml sched_reply_einstein.phys.uwm.edu.xml sched_request_einstein.phys.uwm.edu.xml statistics_einstein.phys.uwm.edu.xml stdoutdae.txt time_stats_log I searched all files for the current "bad" config and was not able to find anything except in global_prefs.xml. The config in sched_request_einstein.phys.uwm.edu.xml is a "good" one. I believe, the bad config comes from boinc-client itself. Important: there was no query/connection to Bam after 20:28 yesterday (according to the Bam hosts list), all files starting with "acct_mgr_*" in /var/lib/boinc-client were changed 20:28 last time. stderrdae.txt is empty. Any ideas? Best wishes, Alex ID: 57846 ·

Hi, thanks for helping me! :-) Did you last change the preferences at BAM on the 17th of November at 13:17:40 hours (presumably UTC)? Good question, I can't say for sure if there was a change then. I manage several computers with Bam and added recently some more, so I am optimizing settings in Bam quite often at the moment. I would say yes, there was a change of the preferences in Bam.

No, no don't see what that would fix, no don't see what that would fix either, and well perhaps on the latter. After you made a backup of everything there, I hope. ID: 57961 ·

Hi, I don't disagree with the above discussions - but would like to ask if adding a project with "add project" instead of "account Manager" would avoid the problem? Respectfully, Jay ID: 58002 ·

It probably would, but then that will fix it for one computer only. The account manager is there to easily add multiple projects to multiple computers, instead of having to manually add each project on each computer. And even while --for testing-- adding the project manually is a good thing, in the end we'd all want this to be fixed, if possible. ID: 58010 ·
