2) Questions and Answers : Windows : Why can't I join the task? (Message 455) Posted 23 Sep 2020 by Sergey Kovalchuk Post: So what can I do nothing. the project has no tasks for active applications
3) Message boards : Number crunching : no work (Message 425) Posted 4 Aug 2020 by Sergey Kovalchuk Post: Multichunk RTS 0 Singlechunk RTS 0 Total RTS 360 is it a hidden secret app?
4) Message boards : Number crunching : Tasks in Progress ? (Message 421) Posted 3 Aug 2020 by Sergey Kovalchuk Post: check the logs - the first tasks had a syntax error in the scheduler response. for the server they are considered sent, for the client they are lost two options: wait for the deadline or activate the "resend lost tasks" option on the server. the second option extra load for the server, but the tasks will go to the client immediately, at the first request for work
5) Message boards : Number crunching : new app - syntax error (Message 406) Posted 2 Aug 2020 by Sergey Kovalchuk Post: 1st task request gave a syntax error 02-Aug-2020 19:40:49 [minecrafthome] Sending scheduler request: To fetch work. 02-Aug-2020 19:40:49 [minecrafthome] Requesting new tasks for NVIDIA GPU and Intel GPU 02-Aug-2020 19:40:50 [---] can't parse file_ref in result: unexpected XML tag or syntax 02-Aug-2020 19:40:50 [minecrafthome] Can't parse task in scheduler reply: unexpected XML tag or syntax 02-Aug-2020 19:40:50 [minecrafthome] No close tag in scheduler reply contents of the scheduler response <workunit> <rsc_fpops_est>30000000000000000.000000</rsc_fpops_est> <rsc_fpops_bound>60000000000000000.000000</rsc_fpops_bound> <rsc_memory_bound>500000000.000000</rsc_memory_bound> <rsc_disk_bound>1000000000.000000</rsc_disk_bound> <name>kaktoos_y62_7_12025908428800</name> <app_name>kaktoos</app_name> <command_line> --start 12025908428800 --end 12094627905536 </command_line> </workunit> <file_info> <name>kaktoos_y62_7_12025908428800_1_r413723412_0</name> <generated_locally/> <upload_when_present/> <max_nbytes>100000000</max_nbytes> <url>https://minecraftathome.com/minecrafthome_cgi/file_upload_handler</url> </file_info> <result> <report_deadline>1596645644</report_deadline> <wu_name>kaktoos_y62_7_12025908428800</wu_name> <name>kaktoos_y62_7_12025908428800_1</name> <file_ref> <file_name>kaktoos_y62_7_12025908428800_1_r413723412_0</file_name> <open_name>kaktseeds.txt</open_name> <copy_file>1</copy_file>git </file_ref> <platform>windows_x86_64</platform> <version_num>101</version_num> <plan_class>cuda</plan_class> </result> the next request passed without errors the error has already occurred in other projects, probably after updating the server [update] you can activate the option - resend lost tasks then the task with an error will not hang until the deadline, but will be delivered on the next request
6) Message boards : Number crunching : 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED (Message 386) Posted 28 Jul 2020 by Sergey Kovalchuk Post: tested on another host. at the start there was a performance value <app_version> <app_name>kaktwoos</app_name> <flops>14600245329561.041016</flops> after receiving WU, the value almost doubled <app_version> <app_name>kaktwoos</app_name> <flops>23668459158711.167969</flops> the new value is received from server along with WU (sched_reply.xml) you greatly overestimate the application performance for some GPUs. or underestimated the overall difficulty of the task (<rsc_fpops_bound>) PS. with 10k active tasks, the number of RTS decreases too slowly. probably a lot of resend tasks
7) Message boards : Number crunching : 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED (Message 384) Posted 27 Jul 2020 by Sergey Kovalchuk Post: exceeded elapsed time limit 2131.29 (60000000.00G/28151.98G) the reason for this is in the number - 28151.98G, each host has its own task was completed by the hosts with the GPU GTX 1650 and GTX 970
8) Message boards : Number crunching : 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED (Message 381) Posted 26 Jul 2020 by Sergey Kovalchuk Post: task kaktwoos_2.04_0148_213454727715161_0 exceeded elapsed time limit 2131.29 (60000000.00G/28151.98G) GPU Tesla P100 is too weak for this task :-(
9) Questions and Answers : Web site : House keeping (Message 296) Posted 18 Jul 2020 by Sergey Kovalchuk Post: Probably bots use not a web interface with recaptcha, but RPC (BM interface) this can be blocked by another Turing test - an invitation code printed on the home page near the join button, something like minecraft or kaktwoos for some reason this is not in the document ProtectionFromSpam
10) Questions and Answers : Web site : House keeping (Message 292) Posted 18 Jul 2020 by Sergey Kovalchuk Post: As for the credit requirement, check out https://boinc.berkeley.edu/trac/wiki/ProtectionFromSpam. Don't use Akismet though, it'll make it very difficult to post URLs, even to your own forums. A lot of the automation (thread locking, removing of spammers etc.) were ideas of mine David Anderson implemented at the BOINC forums, and then when mature enough put out for everyone else. server under attack by spam bots Users - Registered in past 24 hours 3215 admin intervention is required
11) Message boards : News : Enjoy the scenery (Message 287) Posted 18 Jul 2020 by Sergey Kovalchuk Post: The panorama app is a CUDA-only app for Linux and Windows with an Nvidia driver version of 418.96 or higher. Plan class says 418.39, so do check you have the correct driver both sides. changed since it was posted first got a warning 17-Jul-2020 17:01:59 [minecrafthome] NVIDIA GPU: Upgrade to the latest driver to use all of this project's GPU applications then I was able to receive and complete the task (driver 418.67) --- [edit] I couldn't start the task at 650 CUDA: NVIDIA GPU 0: GeForce GTX 650 (driver version 451.67, CUDA version 11.0, compute capability 3.0, 1024MB, 947MB available, 100 GFLOPS peak) error immediately after start GPUassert: the launch timed out and was terminated (code 702) grass_crack.cu 654
12) Message boards : News : Enjoy the scenery (Message 280) Posted 18 Jul 2020 by Sergey Kovalchuk Post: specify the minimum application requirements - GPU model, memory size while I saw continuous errors on GTX 650 (1024MB) driver: 451.67 and GTX 1050 (1999MB) driver: 440.82 and normal work on models GTX 1070 (4095MB) driver: 445.75 and GTX 970 (4095MB) driver: 441.20 PS it is bad that the driver 418.67 does not fit - the number was just a little short ;o)
13) Message boards : News : Kaktwoos 2.03 and Badges! (Message 236) Posted 9 Jul 2020 by Sergey Kovalchuk Post: Is there some code I can steal for this, or am I missing a config toggle? the desired code is already there Your account -> Community preferences -> Hide signatures
14) Message boards : News : Kaktwoos 2.03 and Badges! (Message 231) Posted 8 Jul 2020 by Sergey Kovalchuk Post: Also, we now have badges! it would be better if they were not :( "Top %%" is initially in the project, no need to change the standard (familiar) image They are dynamic (depending on the speed and not on the work performed) and makes sense only within the project. They are not saved by statistics sites and are not used in signatures. The badge "Finder" is acceptable, it’s only advisable to pick up a picture that is associated with the project - if you look at them against the background of huge collections of badge collectors ;) If it’s still a badge "project founder" then it is better to use special roles on the forum
15) Questions and Answers : Web site : House keeping (Message 216) Posted 6 Jul 2020 by Sergey Kovalchuk Post: Enabled the reliable hosts stuff, should solve it for now at the wrong time, it’s too early to ban hosts, first get a stable application and distribution to suitable hosts. can set the task the following parameters max # of error / total / success tasks 10, 10, 3 error = total, can be reduced success = quorum + 1 (accept too late, but successful) [edit] it is necessary to regenerate dead WU - they are normal data and might contain solutions

19) Message boards : Number crunching : Badges. And Stats Export (Message 92) Posted 28 Jun 2020 by Sergey Kovalchuk Post: Badges I'd love to get sorted, I'll have to get our graphics guys to whip up some glyphs to get started there. Any specific thresholds for badges you'd like to see? the badge system depends on how statistics are recorded. will the project have separate independent applications with its own statistics - by application accounting, subprojects? (although it's already a bit late - a decent amount of statistics has been collected) accordingly - separate line of badges specific to the application or different applications will be within the framework of a single accounting system - then the general line of badges. plus badges for special achievements - such as supercactus ;o) in order to estimate the badge scale, you need to know the maximum amount of calculations and the list of project tasks. it’s just the time for the “science” section of the forum - a couple of posts describing the project’s objectives and intended goals. looking at current statistics - first, the start badge should be at the level of 100k - a couple of days of work for an average PC
20) Message boards : Number crunching : Multi-GPU Support (Message 80) Posted 28 Jun 2020 by Sergey Kovalchuk Post: Einstein greatly redone the interface but you can ask the admins Collatz and SETI (until these ran away after closing) ;o)
