4) Questions and Answers : Wish list : Additional options for number of tasks to download Message 52558 Posted 22 Oct 2025 by mmonnin	The only way to perform OPs request is to have separate BOINC clients on a PC each running one of the LHC apps.
5) Questions and Answers : Wish list : Additional options for number of tasks to download Message 52551 Posted 20 Oct 2025 by mmonnin	I make a local config https://github.com/BOINC/boinc/wiki/Client-configuration <app_config> <app> <name>Atlas</name> <max_concurrent>2</max_concurrent> </app> <app> <name>CMS</name> <max_concurrent>4</max_concurrent> </app> <app> <name>XTrack</name> <max_concurrent>12</max_concurrent> </app </app_config> This does not change how many tasks are downloaded.

10) Message boards : Xtrack/SixTrack : Xtrack (Xboinc) Message 52455 Posted 4 Oct 2025 by mmonnin	Some of the tasks progress the %, others jump from 0.10 % to completion. From the tasks I've been able to watch, its ones with flat in the name that jump to 100%. Due to the crazy high ETA, the client will not ask for more work as it's expecting the tasks to run basically forever. Tasks with round in the name only have 500 FLOPS vs 500k FLOPS with flat in the name so the % completion actually works even with similar run time. camontan__tune_scan_start_of_collapse_flat_scan_195__ScanShort_2_1__Hm6gxUEpNDDl_0

12) Message boards : Xtrack/SixTrack : Xtrack (Xboinc) Message 52445 Posted 3 Oct 2025 by mmonnin	While I also prefer a static credit per task, projects like E@H have much more consistent run time at any given time. On one of my PCs I see run times of 400s to 10,000 seconds.

Computers : Registered in past 24 hours : 1457 https://lhcathome.cern.ch/lhcathome/server_status.php Users always come out of the woodworks for non-VB tasks at LHC. Same thing for SixTrack when it had work.

Not the queue buffer or the benchmark. This is up to the project, not the user. On top of the poor flops estimate, the tasks very in run time but there is no variation in the task setup. This type of task runs for 30-35 min camontan__tune_scan_end_of_levelling_scan_134__ScanShort_17_3__jR1XCEh0dIuY_0 While this type runs for 3.5-4 hours camontan__tune_scan_start_of_collapse_round_scan_135__ScanShort_40_2__7pq3Q73qWe7d_0 Yet both have the same estimate in between at 53 min

16) Message boards : Xtrack/SixTrack : Xtrack (Xboinc) Message 52310 Posted 24 Sep 2025 by mmonnin	The app on LHC-dev has VERY low ETAs as in a couple min vs reality of possibly days. Possibility as in the tasks ran from 30 min to 4 days on the same PC. They also run to 100% quickly then sit there for days. Hopefully the low ETA and running to 100% is fixed as it doesn't play nice with how the client operates. As some have seen, be wary of admins dumping work so no one gets credit for completed work.
17) Message boards : CMS Application : CMS@Home -- jobs update Message 51363 Posted 7 Jan 2025 by mmonnin	https://lhcathome.cern.ch/lhcathome/result.php?resultid=418694926 Run time 46 min 22 sec CPU time 33 min 47 sec Ya don't want logs? Posting task links is not useful for history as task data is purged. I've often come to BOINC forums and been unable to verify if I am having the same issue as described as only a link was posted. It also doesn't help when searching either. For this PC, I was able to fix the vbox issue on this PC yesterday by searching LHC forums with the error. This was only possible because someone posted their log.
18) Message boards : CMS Application : CMS@Home -- jobs update Message 51361 Posted 7 Jan 2025 by mmonnin	All the tasks I've gotten on Linux PCs have been single threaded even with it set to be 4 threads in LHC preferences. The lone task I've completed in Win10 was mt. Both say Setting CPU Count for VM. (4) Dev site seems to be missing but services must be up as I can download a task.
19) Message boards : CMS Application : Why all CMS virtualbox task were all failed... host was damaged? Message 51327 Posted 25 Dec 2024 by mmonnin	https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=6265&postid=51310#51310 There is no point running CMS atm as no work s being sent to the VM Task.
20) Message boards : CMS Application : Short CMS-Tasks ok? Message 51252 Posted 6 Dec 2024 by mmonnin	The server hardware is being swapped around. Major reconfigurations are taking place. In other words - the machines the volunteers connect to are taken off line sporadically during this. There is no work is available while the entire LHC@home crew are all busy doing this There's just no need to cater for generating the BOINC volunteers work while the system is mostly off line. The work units that 'pop out' are just empty data transport vehicles with no actual LHC@home data for crunching in them. The data transport system is functioning but there are no "passengers", or in this case data in them. There are gaps but often there is work available from the LHC@home project during this maintenance. I still have a very long Theory job running from last week. Last week saw ATLAS jobs available too. Sometimes you get all three at the same time. CMS, ATLAS & Theory! These empty tasks are, some think, a bit of a waste of time. Stop them if you want. I stopped pulling CMS work units a few days ago. To do this: Click on the "Project" item in the menu bar at the top of any LHC@home web page. In the drop down list select "Preferences". Click "Edit preferences". Un-check the "CMS Simulation". Un-check "If no work for selected applications is available, accept work from other applications?" (Leave everything else alone!) Click "Update preferences". -------- So it's just a matter of time before we see a completion of the maintenance upgrades. It's a big old system y'all. Patience needed by all. Bro, you're replying to the LHC overall #3, #11 and #18 users with nearly 1b credit. They know how to edit BOINC preferences.
