1) Message boards : Number crunching : Server can't Open Database (Message 3191) Posted 19 days ago by Jean-David Beyer Post: Hehehe...I got work, not a lot just 345 jobs, You call that not a lot of work! The last work I got, about 2 weeks ago, was 16 jobs and the previous work was 15 jobs. 0.05 and 0.04 respectively. For the earlier tasks, I would get several hundred tasks at a time.
2) Message boards : Number crunching : Server can't Open Database (Message 3189) Posted 19 days ago by Jean-David Beyer Post: Can somebody go kick the server? Someone's unplugged it to charge their phone or something again. I got that a few times today, but it has since gone away. I got it when trying to login to the site, so I am mystified at how you managed to post without logging into the site. But none of this matters as there has been no work for about 10 days.

Let's see what the team will say about it. There must have been very few. I got none. My Boinc client has been getting so few in the last week that it tries seldom.

5) Message boards : Number crunching : New version 0.05 of DENIS-Fiber_beta (Message 3173) Posted 28 days ago by Jean-David Beyer Post: These are all from my Linux machine (my biggest and fastest). 0.01, 0.02, and 0.03 tasks ran very fast and I did a lot of them. I could do them in about 1/2 a week and then there were none until the next week. I seem to remember thes tasks took about 20 minutes each. 0.04 and 0.05 tasks were larger and seemed to take about 7 1/2 hours each. So the server gave me fewer of these. But since they had much greater expiry date, I could have completed at least twice as many as the server chose to give me. The server seems to think I could do around 500 tasks per day, but gives me only about 15 per week. Very disappointing.

6) Message boards : Number crunching : New version 0.05 of DENIS-Fiber_beta (Message 3164) Posted 3 Jun 2025 by Jean-David Beyer Post: I wouldn't abort any work units... I agree, unless they have have expired already. Because the work is intermittent I suspect people hog the work units and download what they think will be enough to get them through the next scarcity period. For earlier tasks (0.01 to 0.02) this would not have worked for me because if I ran through a bunch in 3 days, but got new work only about once a week, getting more work when available would have timed out since they expired in about three days. Given the long deadline to these workunits people will be hogging even more. It would be nice if there were a more even distribution of work for all... I just crank away at other projects when there is no Denis to be had. Except for WCG, if I diddle the amount of work in the boinc client to get, it applies to all projects,, and if I set it to get more work for Denis, it would get more for all the others too. No problem for ClimatePrediction that does not send out work. But for others, this would be a mistake.
7) Message boards : Number crunching : New version 0.05 of DENIS-Fiber_beta (Message 3161) Posted 3 Jun 2025 by Jean-David Beyer Post: Just got some version 0.05, not started yet. Should version 0.04 units be aborted? Tha does not happen to me. When I get a supply of work units, I almost always complete them long before another set becomes available. In the old days, they expired in less than a week, but I could almost always complete them in about three days, so I had no Denis work more than half the time. These new (0.04 and 0.05) work units have a longer expiry date (about three weeks), so I get much fewer units than before. And they take about 7.5 hours each to run. My app_config file allows three of these tasks to run at a time, so I still run out long before the next batch arrives. So it looks as though I willl never have the problem implied by your question. It makes me wonder how you can get so much work on this project as to not finish a set before the next set arrives.
8) Message boards : Number crunching : New version 0.04 of DENIS-Fiber_beta with checkpoints (Message 3158) Posted 2 Jun 2025 by Jean-David Beyer Post: There was a new batch of 1000 WUs/2000 tasks, but because of its small size it pretty much disappeared instantly. I only managed to grab 16 of them on my dedicated MiniPC. It was so small I did not get any. On a side note, I got a resent task for a WU in which both initial tasks came back inconclusive. Anyone else noticed such resends? Would be interesting if the team told us what causes this phenomenon. No resends either.

10) Message boards : News : New version with checkpoints // Nueva versión con checkpoints (Message 3130) Posted 27 May 2025 by Jean-David Beyer Post: The chekpoint interval also depends on your computing preference: Oops: I forgot about that. Mine is set to 1801 seconds (about every half hour). But so many projects seem to ignore this that I forgot about it.
11) Message boards : News : New version with checkpoints // Nueva versión con checkpoints (Message 3126) Posted 27 May 2025 by Jean-David Beyer Post: I note that the tasks are very long - in excess of 14 hours on my laptop. Checkpoints are very regular - every few seconds. These 0.04 asks are a lot longer than the 0.03 tasks. IIRC, those were around 20 minutes each and these seem to be around 7 hours on my main (Linux) machine. So maybe my machine is twice as fast as yours. The current checkpoint was about 13 minutes ago and another one was about 25 minutes ago. I would not call those "every few seconds."

12) Message boards : Number crunching : Why can't I get a job? (Message 3084) Posted 20 May 2025 by Jean-David Beyer Post: I'm about full but looks like all gone now. It says there are 225 tasks available as I type this. I got about 250 earlier today on my main (Linux) machine and am running 3 of them at a time. Their deadline is around 8AM local time Friday, but I guess I will finish them sooner than that.
13) Message boards : News : We are back! // ¡Estamos de vuelta! (Message 3057) Posted 12 May 2025 by Jean-David Beyer Post: It's now 12 May and nothing to work on. Did it finish while I wasn't looking? Or is something broken? I think neither of the options you suggest are the case. I am a relative newcomer to Denis, but it seems to me that it runs sporadically. My experience is the following. At the beginning of each week, a fairly large group of tasks are made available. They have an expiry date of about three days, so even if you can get more, there is no point. Then for the rest of the week, no new tasks become available. There are exceptions to this. I did get a week or so recently where tasks were available all week. But also, there are times much longer than a week where no tasks are available. This seems to be one of them. (I hope I am wrong.)
14) Message boards : Number crunching : Why can't I get a job? (Message 3051) Posted 7 May 2025 by Jean-David Beyer Post: I'm doing RAH,GPUgrid and Denis for medical and FAH (not BOINC) and then some math and LHC and Einstein plus Astroids. I never run dry..I just do more of other stuff when some projects are down. I am trying to do ClimatepRrediction, Denis, WorldCommunityGrid, Asteroids, Rosetta, and Einstein. I sometimes run dry as now my main (Linux) machine only has enough to keep 10 cores busy. No work for ClimatePredicion, Denis, Asteroids, Einstein. And Asteroids does no work on my Linux machine alhough it does on my Windows 11 machine. CPDN has been out of work for months, WCG was down most of the last two years, though it is slowly recovering. Einstein has been out of work for a couple of days. And Denis is in its on-again off-again mode after having run quite well for several weeks.
15) Message boards : Number crunching : Stat's Export (Message 3004) Posted 24 Apr 2025 by Jean-David Beyer Post: I am now getting stats using RPC and also the RSS news feed is now working. Whatever the IT team have done may have solved the export for others as well. Me too, at last. The Denisahom line in my BoincStats signature box now has numbers (probably correct) in it.

20) Message boards : Number crunching : Beta of DENIS-fiber (beta test) Windows performance (Message 2867) Posted 15 Apr 2025 by Jean-David Beyer Post: I notice that my Windows 11 machine still takes about 1 hour 45 minutes per work unit, where my Linux machine takes just avout 21 minutes. Both are still version 0.02, so I guess the Windows 0.03 version has not yet made it to my machine yet.
