1) Message boards : Number crunching : Completed, validation inconclusive, credit pending (Message 63307) Posted 31 Mar 2015 by Marek Majewski Post: Thanks, now I understand. -mm- P.S. Your answer should be pinned as it fully explains the difference. Thanks again.
2) Message boards : Number crunching : Completed, validation inconclusive, credit pending (Message 63304) Posted 30 Mar 2015 by Marek Majewski Post: See my reference to Adaptive Replication Richard, thank you. I have read that, and unfortunately I am not the wiser. Is there a user-friendly explanation on how VALIDATION INCONCLUSIVE varies from VALIDATION PENDING, or did I just read it in the link you provided and I am denser than Ununoctium? It is quite possible I should be added to the periodic table with the atomic number of 119. :-) -mm-
3) Message boards : Number crunching : Completed, validation inconclusive, credit pending (Message 63302) Posted 30 Mar 2015 by Marek Majewski Post: Work units are sent to more than one cruncher to process. After you return results that are somewhere near what the project expects them to be, you are now waiting for another cruncher to return the same results you did, plus or minus an acceptable margin of error. Validation inconclusive WUs are the units waiting for another cruncher to report results. I thought this is VALIDATION PENDING. I have several units in either state on one of my computers, but I have never seen VALIDATION INCONCLUSIVE coming from the another one. Can you elaborate, as I am sill confused... Thanks for your time. -mm-

VALIDATION PENDING (this I think I do understand), and 2. COMPLETED, VALIDATION INCONCLUSIVE, CREDIT PENDING (this I do know I don't understand). Thanks, -mm-
5) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63297) Posted 28 Mar 2015 by Marek Majewski Post: Ah. My fault, should have checked. "Darwin 14.1.0". LHC doesn't have a current application for Macs. Oh, I see. So BOINC client lied to me, because it clearly displays a MAC OS logo under supported systems when trying to attach to LHC@home from BOINC manager. Thanks for the info. It is a shame; a vast majority of scientists I have ran across (and their students, for that matter) use MACs. Something tells me folks at CERN are no exception. One would think they would make an effort to port the thing to OS X. It is based on BSD, after all. Oh well...I can load Windows under VMFusion, I suppose, but this just seems as way too much hustle to maintain. A hobby should not be a chore, don't you think? -mm-
6) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63296) Posted 28 Mar 2015 by Marek Majewski Post: You have not been getting work for the LHC - SixTrack project because they currently do not have an application that will run on Darwin / MAC. Does that mean there is no LHC sub-project available for Darwin / MAC, or that SixTrack will not run on a MAC but some other sub-projects of LHC will? -mm-

8) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63292) Posted 28 Mar 2015 by Marek Majewski Post: If you highlight the LHC project in BOINC Manager, and click the 'Update' button, what sequence of messages (request and reply) do you get in the event log? 1. Scheduler request pending, Requested by user. 2. Scheduler request in progress. 3. Communication pending (countdown 00:00:05) and then: 4. Scheduler request pending. To fetch work, Scheduler request in progress And nothing shows up from LHC among tasks when viewed "Tasks / Show all tasks". Only work from SETI and MW is there. -mm-
9) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63290) Posted 28 Mar 2015 by Marek Majewski Post: I joined LHC three days ago, and did not receive anything to work on since. I used the correct URL, and it seems that project has work, I just did not receive anything yet. Sorry for asking about LHC on MW, but I am in an unpleasant catch-22: I did not process anything for LHC, because I did not get any work yet, so I don't have any credit, and I need credit to post on LHC's forums, so I can not ask there. LOL. It seems from their status page that wotk is available: http://lhcathomeclassic.cern.ch/sixtrack/server_status.php Actually, there is: Tasks ready to send 553,650 at the moment of my typing this message. Yet, my BOINC client did not receive a thing since I signed up. It communicates with the project, and nada! I even tried to RESET and REMOVE/ADD LHC@HOME, and nothing. Any ideas? -mm-
10) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63289) Posted 28 Mar 2015 by Marek Majewski Post: LHC often doesn't have work, but just at the moment they're really busy and would appreciate your help. Make sure you're attached using the correct url - they did change it a while back. http://lhcathomeclassic.cern.ch/sixtrack/ I joined LHC three days ago, and did not receive anything to work on since. I used the correct URL, and it seems that project has work, I just did not receive anything yet. Hm... -mm-
11) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63287) Posted 28 Mar 2015 by Marek Majewski Post: I first posted my last message (above) and then realized that there are more replies. After I read them, I am under the impression that what I was witnessing is a NORMAL behavior of BOINC trying to have MILKYWAY catch up with SETI. If I understand it correctly it is possible that one can crunch for one project for years, accumulating a large credit, and then decides to join another project, and that basically puts the old project more or less on hold until the newly joined project catches up? Can somebody confirm or deny? Thanks. -mm-
12) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63286) Posted 28 Mar 2015 by Marek Majewski Post: Thanks for the suggestion. Here is what the scheduling priorities for all my projects are as displayed in Project tab / Properties: LHC@ = -0.00 (did not receive any tasks since I joined the project, as the project seems to be taking a short break). POGS = -0.00 (did not receive any tasks since I joined the project, as the project seems to be taking a short break, same as LHC). SETI@ = -3.77 (I joined this project first and processed probably 40K worth of credits on this host). Currently I process only for SETI@. MILKYWAY@ = -0.00 (I joined this project second, and processed probably 1,800 worth of credits on this host. Currently I drained my queue and asked BOINC not to fetch any tasks until I figure out the problems with switching in between projects). I remember looking at the scheduling priority when MILKIWAY was doing work, and it was a non-zero, negative number, closer to zero than the -3.77 I have for SETI, but I do not remember exactly what it was. Resouce share on all of the four projects the sites is set to 100 each, so in theory each project should get a 25% slice. I do not understand how the scheduling priority works, neither I know where from to control it. Can you point me in an approximately right direction? Thanks for your time. -mm-
13) Message boards : Number crunching : Boinc not switching away from Milkyway (Message 63279) Posted 27 Mar 2015 by Marek Majewski Post: I am running BOINC ver. 7.4.36 with SETI@ and MILKYWAY@ projects on a Mac OS Yosemite. BOINC switches from SETI to MW just fine after the prescribed 30 minutes as per the directive in preferences, but then does not switch back to SETI and stays crunching MW. The only way I can force it to switch to SETI is to suspend MW, then SETI picks up, and the cycle repeats. Switches to MW after 30 minutes, and clings on to it indefinitely. I tried all I can think of, but to no avail. Any ideas? -mm-
