21) Message boards : Questions and problems : rpc changes (Message 100912) Posted 1 Oct 2020 by Toby Broom Post: Sorry, You have the gui_rpc_auth.cfg which is enforced now. remote_hosts.cfg which is white list of host, this is sort of redundant now as you need the key from gui_rpc_auth to make a connection, so kind of white list on client vs server.
22) Message boards : Questions and problems : rpc changes (Message 100704) Posted 11 Sep 2020 by Toby Broom Post: Hi, I'm all for the security improvements, but it seems redundant to provide 2 different mechanisms to secure communications between boinc clients? Could it be considered to use a single mechanism? Thanks for consideration
23) Message boards : Questions and problems : Peer certificate cannot be authenticated with given CA certificates (Message 98909) Posted 30 May 2020 by Toby Broom Post: Seems like the windows version of BOINC should do something like that, so the same thing doesn't happen next time certs expire?
24) Message boards : Questions and problems : Peer certificate cannot be authenticated with given CA certificates (Message 98903) Posted 30 May 2020 by Toby Broom Post: I made the updated file for anyone that "trusts" me. https://1drv.ms/u/s!AsVDg7OAm7-whqEqBXKHuOie0UoBKA?e=VHwBAP I can also confirm it works

26) Message boards : Questions and problems : Editing RAM usage for project (Message 92808) Posted 15 Sep 2019 by Toby Broom Post: Hi, For my LHC@Home project the project team do not calculate the amount of RAM usage correctly so I would like to fix it client side. I am able to edit the rsc_memory_bound & working_set_size_smoothed to the correct values but the scheduler doesn't seems to see that the memory load is reduced. How does the calculation of the free memory work? 75 09/15/19 15:20:54 [mem_usage] enforce: available RAM 128359.19MB swap 75217.38MB 76 LHC@home 09/15/19 15:20:57 [mem_usage] (not running)Theory_2417912_1568071912.492574_0: WS 84.60MB, smoothed 5120.00MB, swap 103.84MB, 0.00 page faults/sec, user CPU 16.063, kernel CPU 1923.344 77 LHC@home 09/15/19 15:20:57 [mem_usage] (not running)Theory_2475718_1568080319.011424_0: WS 85.05MB, smoothed 5120.00MB, swap 103.87MB, 0.00 page faults/sec, user CPU 22.547, kernel CPU 3868.422 78 LHC@home 09/15/19 15:20:57 [mem_usage] (not running)Theory_2505470_1568084822.594092_0: WS 85.52MB, smoothed 5120.00MB, swap 100.29MB, 0.00 page faults/sec, user CPU 19.781, kernel CPU 3618.375 79 Radioactive@Home 09/15/19 15:20:57 [mem_usage] sample_10775727_0: WS 4.75MB, smoothed 4.75MB, swap 6.39MB, 0.00 page faults/sec, user CPU 0.000, kernel CPU 0.063 80 LHC@home 09/15/19 15:20:57 [mem_usage] (not running)Theory_2471900_1568079718.688719_0: WS 84.43MB, smoothed 5120.00MB, swap 94.43MB, 0.00 page faults/sec, user CPU 3.313, kernel CPU 44.984 81 LHC@home 09/15/19 15:20:57 [mem_usage] Theory_2386456_1568067408.805761_0: WS 86.16MB, smoothed 5120.00MB, swap 96.68MB, 0.00 page faults/sec, user CPU 7.016, kernel CPU 188.047 82 LHC@home 09/15/19 15:20:57 [mem_usage] Theory_2513686_1568086023.457098_0: WS 89.50MB, smoothed 5120.00MB, swap 101.08MB, 0.00 page faults/sec, user CPU 6.484, kernel CPU 176.688 83 LHC@home 09/15/19 15:20:57 [mem_usage] Theory_2520971_1568087224.201573_0: WS 89.66MB, smoothed 5120.00MB, swap 101.04MB, 0.00 page faults/sec, user CPU 5.813, kernel CPU 137.344 84 09/15/19 15:20:57 [mem_usage] BOINC totals: WS 609.68MB, smoothed 35844.75MB, swap 707.62MB, 0.00 page faults/sec 85 09/15/19 15:20:57 [mem_usage] All others: WS 3381.68MB, swap 3284.45MB, user 6516.125s, kernel 6734.047s 86 09/15/19 15:20:57 [mem_usage] non-BOINC CPU usage: 0.00%
27) Message boards : Questions and problems : Simulate an amount of memory (Message 90768) Posted 21 Mar 2019 by Toby Broom Post: Is there an setting similar to <ncpus> but for memory? thanks
28) Message boards : Questions and problems : Maximum CPUS (threads) supported by BOINC client (Message 90767) Posted 21 Mar 2019 by Toby Broom Post: I think these limits are server side. See these config options, for a project. <max_ncpus>N</max_ncpus> An upper bound on NCPUS (default: 64) I can imagine that most projects didn't increase this from default so you are correct. I do what you propose which is run 2 clients on the same PC, you have to take care about the memory usage, since both clients think they have all the ram, so if your pushing the ram limits then you can end up with very slow computer. I'm not sure if the limit is 1000?, it should be 64x<max_wus_in_progress> N </max_wus_in_progress>, whatever the project configures N to be. Each project should balance this, as you say if they set it low then the users of project would be hammering the server for WU's so they need to increase it to lower server load. I assume the client it's self has no limits. If you need more than 64 then you can ask the project admins to increase the limits to 128.
29) Message boards : Questions and problems : Adjust Working Set Client-Side (Message 87227) Posted 22 Jul 2018 by Toby Broom Post: Can I adjust the working set size of tasks from the client? The project I'm connected to allows between 1-8 work units at a time or an unlimited option, when the option is set to 1 for example then the working set is correctly calculated, however your are limited to 1 WU at a time which is wasteful given my computers have many more than 8 cores. If I choose unlimited then I can use the work buffers as set in the BOINC config but the working set is not calculated correctly anymore so once it thinks it's used all the memory then it will not start any further work.
30) Message boards : Questions and problems : Suspend CPU when there is GPU work (Message 85742) Posted 5 Apr 2018 by Toby Broom Post: Hi is it possiable to suspend CPU work when there is GPU work? It seems like the suspend option stops everything and the GPU works the other way around.
31) Message boards : Projects : Which BOINC projects use the most memory? (Message 84182) Posted 3 Jan 2018 by Toby Broom Post: I'm able to use about 100GB of ram on ATLAS project, the 1.4GB number is not correct anymore it's at least 2.6GB
32) Message boards : Projects : Radioactive@Home domain is dead. (Message 84181) Posted 3 Jan 2018 by Toby Broom Post: It was working up until a few weeks ago, I think we have to wait for a while to see if it's really dead.
33) Message boards : Projects : For the betterment of BOINC (Message 79816) Posted 27 Jul 2017 by Toby Broom Post: 1. I don't find the Disk and Statistics much use, I find that the statists are better servered on the website like boincstats etc. I always use the advanced view. BoincTasks is super valuable tool. the concepts of jobs, tasks, wu's are hard to configure on these virtualbox projects. I still have strange effects like some settings cause my PC to run 1 task when I set to unlimited for example. I think this is becasuse it too hard for the admins to make correct configurations. The projects like this are beyond a normal user to setup. I don't critise this help as its excellent but a avergae person wouldn't have a clue what to do. https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4161#29359 editing client_state.xml etc... Boinc knows the specs of your PC so it could help you? I like davids concept that you would optin to an area of science, this makes it more likly that people would join projects as now you have to discover them so how. Currently project are optin mabybe optout would be better, athough maybe an invasion, athough you optin to BOINC I it would be nice if BOINC could post to socialmedia that I achived something for science, found new prime or computed a low energy confimation. Since we give our resources to the projects I have to wonder what is the return, from davids comments it seems like the main users are people that liek to tinker with computer so they do it for those reasons. Gridcon maybe to make money. I imagine for many people these aren't such motivating reasons. 2. I'm not sure what I could do?
34) Message boards : BOINC client : My Wish List (Message 77263) Posted 10 Apr 2017 by Toby Broom Post: Some project are non cpu intensive and the multithreaded ones can be limited to a specificed number of cores so I would like to know how it's all working.
35) Message boards : BOINC client : My Wish List (Message 77249) Posted 9 Apr 2017 by Toby Broom Post: Can the boinccmd --get_tasks report the number of CPU/GPU cores used by the task?
36) Message boards : Questions and problems : Controling blend of mutlicore and single core VM's (Message 77096) Posted 1 Apr 2017 by Toby Broom Post: I finally got it to work The project_max_concurrent is jobs, so it will always run that many tasks regardless of the number of cores per task. I forced the number of CPU's as per your suggestion. Now it respects the number of cores correctly. I can also limit the number of cores in use with the Use at most N% or the <ncpus>. I think the concept of a job is quite confusing, not sure why it would be useful, max cores per project would be better?
37) Message boards : Questions and problems : Controling blend of mutlicore and single core VM's (Message 76708) Posted 22 Mar 2017 by Toby Broom Post: I expect still does not work correctly? This would be my expected configuration <app_config> <project_max_concurrent>8</project_max_concurrent> <app> <name>Dual Core</name> <max_concurrent>4</max_concurrent> </app> <app> <name>Single Core</name> <max_concurrent>8</max_concurrent> </app> </app_config> My example run time of 4 Dual & 4 Single is fine with this config but use 12 cores. BOINC knows that the dual core task core take 2 core as the tasks have (2 cores) after the name, it just doesn't seem to respect the limits.
38) Message boards : Questions and problems : Controling blend of mutlicore and single core VM's (Message 76543) Posted 19 Mar 2017 by Toby Broom Post: I have some tasks that are mutli core and some single core, I can create an app_config like so: <app_config> <project_max_concurrent>8</project_max_concurrent> </app_config> This will limit the number of tasks to 8 total, however if I have 8 dual core then this is actually 16 cores of usage. So I can create a limit like so: <app_config> <app> <name>App2</name> <max_concurrent>4</max_concurrent> </app> </app_config> This limits the app to 4 so 8 cores. However, if I have 4 of App1 & 4 of App2 then both conditions are met 8 total and 4 of app2 but the total number of cores used is 8+4 so again over used. Is there a way to configure BOINC so it will respect the number of cores? BOINC 7.6.33, Windows 10, LHC@Home, not installed as service
39) Message boards : Questions and problems : cc_config, appnames (Message 52074) Posted 21 Jan 2014 by Toby Broom Post: It's not bad for one computer but kind of a pain for 8 of them. Thanks for feedback, I'll write up a script to make my life easier.
40) Message boards : Questions and problems : cc_config, appnames (Message 52069) Posted 21 Jan 2014 by Toby Broom Post: Hi, I have in my cc_config to stop GPU work when the CPU is fully loaded so I added the name of the app e.g.: <exclusive_gpu_app>sixtrack_win32_4463_pni.exe</exclusive_gpu_app> However if the project release a new app e.g.: sixtrack_win64_4463_pni.exe Now I need a new line in the cc_config. Is there a way to wild card it to say sixtrack* then all apps from that project would be exclusive?
