21) Message boards : Number crunching : Project has no tasks available (Message 698) Posted 13 Jul 2020 by Sergey Kovalchuk Post: the impression is that the more tasks, the more difficult it is to get them. the server worked perfectly with 150k RTS and 5k active (even better with 2k active ;o) - for the application perf
22) Message boards : News : iThena CNode (non-beta) badge - badge graphics proposals (Message 696) Posted 13 Jul 2020 by Sergey Kovalchuk Post: example : https://www.bilder-upload.eu/thumb/185ab3-1594629347.png https link to a picture from an external site.
23) Message boards : News : iThena CNode (non-beta) badge - badge graphics proposals (Message 692) Posted 13 Jul 2020 by Sergey Kovalchuk Post: The project has activated per application statistics. It is possible to define separate badges for each application. Given the speed of statistics collection - the number of Win/Lin systems, task duration, etc. Granting badges based on per-app credit The script html/ops/badge_assign_custom.php grants badges based on subproject credit totals. See its comments for instructions.
24) Message boards : Number crunching : Validation Not Working (Message 669) Posted 6 Jul 2020 by Sergey Kovalchuk Post: https://boinc.berkeley.edu/trac/wiki/BackendPrograms The transitioner works asynchronously from work generators and schedulers, and in high-load situations it can fall behind (i.e. a large queue of workunits waiting to be processed can build up). The transitioner backlog is shown in the server status page. If the backlog becomes large (> 1 hour) you can do the following: •stop the project •run sched/transitioner_catchup.php •start the project
25) Message boards : News : iThena Cnode application - new credits settings (Message 662) Posted 5 Jul 2020 by Sergey Kovalchuk Post: The update of the historical "cnode beta" series badges has been disabled. These badges will no longer be changed. new badges (non beta)? New settings will only be visible after a certain period of time. you could clean up all of the old tasks - the losses are negligible (660 active task). 97k / 660 = 4 days
26) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 503) Posted 8 May 2020 by Sergey Kovalchuk Post: the server by default has 4 standard groups - default, home, work, school and standardly implemented option - run only selected applications (+ launch others if there is no work for selected) It would be desirable to start with them - to give an expanded description of the location. and add specific settings for individual specific hosts, for example, a sign of mobility. in addition, the PC is easy to change the location, for example, brought a laptop from work to home for the weekend / vacation - one click and he is "at home"
27) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 477) Posted 1 May 2020 by Sergey Kovalchuk Post: ----------------------------------------------------------- Applications executed on HOST ID XXX: [APP NAME]: [checkbox = yes/no] [APP NAME]: [checkbox = yes/no] [APP NAME]: [checkbox = yes/no] ----------------------------------------------------------- maybe this part is easier to implement with the extended option of user preferences "run select application" for each venue / location (default, home, school, work)
28) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 471) Posted 30 Apr 2020 by Sergey Kovalchuk Post: In fact, I can introduce shorter tasks. But I think 2 hours would be acceptable? the task can be of any duration if at least once an hour there is a checkpoint. it’s better if the real result is saved: processed one server from the list - save the checkpoint In relation to questions: 1) Do you know how the BOINC server currently handles the selection of applications as standard? Does it work correctly on the server/project side? In the past (quite a long time ago) there were problems with it... The choice of application preferences is probably an open problem here. 2) The network load I think will be regulated over time. I can implement the option for the user to define how "difficult" (very big network load? or small?) tasks will be downloaded by a specific client. I read somewhere, sort of like a "local scheduler": 10 levels of difficulty, matching the CPU model (parsing the line), etc. IMHO, too difficult for such a simple task. another idea is an endless task, once an hour packing the result and sending it to the server with a trickle message (search keyword) an example is climate prediction or QCN (sensor and continuous) build a distributed network of measuring agents following the example of a network of seismic sensors :o) PS then crediting is not for the task (it is endless, you can just kill it), but for each sending of the result (each trickle) - an idea from the DHEP project

30) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 468) Posted 29 Apr 2020 by Sergey Kovalchuk Post: the application has been running for about 360 minutes 6 hours continuously and without checkpoint? it is not important for continuous 24/7 work but for work in "business time" 8/5 - there is almost no chance for completion, especially with the option "network required" [upd] about the test. > 2 hours progress 0.00000 stderr - a pack of such messages warning: Ignoring nonsense TCP MSS 4297216 WaitForSingleObject failed.

31) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 467) Posted 29 Apr 2020 by Sergey Kovalchuk Post: Linux (x64): https://root.ithena.net/usr/apps_test/ithena_perf_v1.03_R3_bin_x86_64-pc-linux-gnu.zip Now the choice of application / subproject is essentially unambiguous: CNode only for Linux, PERF only for Windows (NRT is actually abandoned) With the launch of the new version, the situation will change - two applications for Linux. Will it be a user-controlled choice? Or the choice will be up to the server, then what is the algorithm? doubling the number of applications — additional processes on the host, more host resources (will there be conflicts between tasks?), more load on the network — traffic in GB/s is not as worried as the number of connections (for NAT) and their intensity (Mp/s on a router / firewall) on farms where there are many (hundreds) instances, doubling tasks can have disastrous consequences for the user location and, in fact, a DDoS attack on the project site. providers can use mechanisms to suppress such activity again, there will be a question about the equivalence of the assessment for both tasks, and the bonus for the double load on Linux hosts solution to the problem with the credits for the task, in turn, will lead to the issue of badges - it's time to think about their design ;o)
32) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 446) Posted 22 Apr 2020 by Sergey Kovalchuk Post: Is that acceptable? this is a normal requirement, it sometimes requires a really strange ;o) here the main thing is to determine exactly the version you need - it depends on the compilation mode in Visual Studio now requires specified in the post above 2015-2019 yesterday I was looking for a solution - I saw a hint that you can choose the compilation mode as in version 2010. then the requirement for the version 2010 redist is very likely to be “closed” by another BOINC project or some new office suite in general. in addition, complete sets of such packages are included in Windows updates, for example, the full set in Windows Update KB2999226 PS when you proceed to compile the application on Linux, a similar question will arise regarding the requirements of the version of libraries - either too old (forbidden in new distros), or vice versa too new for most users. here is an example
33) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 442) Posted 21 Apr 2020 by Sergey Kovalchuk Post: as I said - now the program needs Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 ;o)
34) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 438) Posted 21 Apr 2020 by Sergey Kovalchuk Post: @Sergey Kovalchuk: You can test R1 on Win7 Pro SP1 x64 without Visual C++ Redistributable? I have other projects there requiring library versions up to 2010 Version 2015 was not required before - I installed it only now
35) Message boards : Number crunching : New applications in the test phase [before the introduction of BOINC iThena] (Message 435) Posted 20 Apr 2020 by Sergey Kovalchuk Post: Win7 Pro SP1 x64 tuxliketimeout_v1.0.exe - System Error The program can't start because api-ms-win-crt-runtime-ll-l-0.dll is missing on the computer. Try reinstalling the program to fix this problem required Visual C++ 2015 Redistributable (x86 и x64) found and installed in addition to previous versions, maybe then a 2017 version will be required - for the full collection ;o)
36) Message boards : News : Maintenance and new version of iThena PERF application - Linux platform - Continuation (Message 421) Posted 18 Apr 2020 by Sergey Kovalchuk Post: Now almost all tasks began to freeze. I do not think that this is due to migration Most likely the network is overloaded with a large number of hosts connected to the project Is there a calculation of the network load when performing your network tests? Although the project has the status of NCI, but unlike similar projects, it simply loads a different type of resources - connections and traffic instead of the CPU. Users may not take this into account simply by using existing “monkey farms” in the project.
37) Message boards : Number crunching : Multi task (Message 413) Posted 13 Apr 2020 by Sergey Kovalchuk Post: perhaps another side of the problem - many ghost tasks from time 12 Apr 2020, 6:49:09 - 7:57:15 UTC maybe it matters - the "cnode" application for Linux, old client, the "perf" application for Windows, a new client has just appeared, very buggy :(
38) Message boards : Number crunching : Multi task (Message 407) Posted 12 Apr 2020 by Sergey Kovalchuk Post: yes, 2 PC * 4 tasks resent lost task - not for NCI project, only 1 task per host
