But Jesus explained it better that I ever could. OTOH: As already mentioned, luckily there are other projects to which you can give your time. That's why we want to be efficient: If we waste your resources, we don't just take it only from you, we take also from other scientists. This project has had its ups and downs, but we are achieving sustained growth. I think this is the way, although I understand that many of you would like another situation. I also want there to be a more constant flow (and less manual part...) True, there are other projects, but in the last few months, even about a year, important (to me) projects have been having miserable availability of work. The worst has been WCG that was pretty much down for about year, though with brief intervals where work was available. Right now it is sending work on two of their efforts, but nominally they have five. And ClimatePrediction has not been sending out work for quite a while too although now their web site is up reliably; just no work since April except for a few re-runs that timed out from other users. As a result, I am now running a lot of MilkyWay and Universe tasks that are of little interest to me, but at least they are pretty reliable about keeping their servers up and supplying work.
22) Message boards : News : Status of the project // Estado del proyecto (Message 2097) Posted 11 Jun 2023 by Jean-David Beyer Post: Why do you wait until the last moron running DENIS on his IBM 8088 green screen PC returns the final task sent out 9 years ago, before you make another batch of tasks? This is HIGHLY INEFFICIENT. If I have told you once, I have told you a million times, don't exaggerate! But a bit more seriously, there are more than one way of measuring efficiency, and perhaps the management of this project has a different idea of efficiency than you do. I admit to getting frustrated by running out of work every week, usually after three or four days. So it is not running my machine efficiently (even though I run CPDN, WCG, Rosetta, Einstein, and (grudgingly) MilkyWay and Universe). But maybe management of this project measures efficiency in terms of efficiency of its machines, its people, and other things.
23) Message boards : News : Status of the project // Estado del proyecto (Message 2095) Posted 31 May 2023 by Jean-David Beyer Post: I will publish an update of the results the next week (we are finishing the validation process of the first version of the optimization), and I will explain there the new versions we have started (the validation of the first one does not look good, so we will still need your help). You will continue getting my help if you continue sending me work units. Currently I have little over 100 DENIS tasks in my machine waiting to go, and I process them four at a time. They seem to take about 65 minutes each on my main machine. And I notice the current batch on your machine is quite large, so I may get some of those too.
24) Message boards : News : Status of the project // Estado del proyecto (Message 2093) Posted 29 May 2023 by Jean-David Beyer Post: I wish there were a way to supply more work, and more evenly. When work becomes available, usually once a week, my machine downloads about 100 tasks. I could make it get more, but that would risk failure to complete some on time, so that is not the answer. Alternatively, you could send out work twice a week, perhaps every three or four days. As I understand it, this is not practical either because you need the results from one batch of work before you can send out the next set of work. Perhaps if you had two related projects, each could send out the same size work once a week, but 3 or 4 days apart, so you could be studying the results of one project while we volunteers could be working on the other. That would probably increase the amount of work you would have to do, of course, and that might be too much to ask for.
25) Message boards : Cafe : OS Selection thread (Message 2091) Posted 4 May 2023 by Jean-David Beyer Post: I prefer RHEL derivatives for private and professional use, because it is important for me to have as much practise as i can get. Me too., Actually I am running Red Hat Enterprise Linux release 8.7 (Ootpa), not a derivatave, My first home computer ran Windows 95 and I hated it so much that I complained to my computer-knowledgeable nephew (an MIT student at the time) and he recommended Red Hat Linux 5 (current at the time), and it was so much better, and less buggy, and free that I got it. I cannot remember if it fit a floppy disk or a CD. But I added a hard drive to my machine and installed Linux on the new drive as a dual-boot system. I then went to RHL 5.2 on a new machine and later upgraded it to CentOS4. I run RHEL on my last few machines. I like that it is supported for 10 years because I hate upgrades (although I to keep with the bug fixes). $ uptime 16:38:49 up 28 days, 6:51, 1 user, load average: 12.07, 12.19, 12.58 $

27) Message boards : Number crunching : What does 1 credit equal? (Message 2077) Posted 18 Apr 2023 by Jean-David Beyer Post: I do not know. The number of credits per successfully-completed tasks varies enormously depending on the project. For example MilkyWay and Universe give out so much credit per work unit that it is embarrassing tp show them. I have generated more credits in a few months of these two than by WCG since 2 Oct 2007. or Rosetta since 2 Nov 2005. I think it would be better if the number of credits were proportional to the amount of CPU cycles executed per task, or something like that. But that does not seem to be how it is done.
28) Message boards : Number crunching : New tasks? (Message 2066) Posted 13 Apr 2023 by Jean-David Beyer Post: There are plenty of other Boinc Projects you can put your machines on to get credits, some even faster than here. ALL Projects go thru phases where they have tasks or they don't, it's why it's called Distributed Computing and soo many Projects have joined in since Boinc came about way back when, the idea being you get to choose where you want to crunch and if one Project is running low on tasks you can always choose another!! True enough.. MilkyWay and Universe give out so much credit for so little work that it is embarassing to even run them. I give them my lowest priorities and allow only one task of each to run at a time. I signed up for them to make up for the lack or work from WCG (now p;ossibly almost fixed) and ClimatePrediction that has an extended period of no new work; and not giving credit for the work that is done. The credit for CPDN work does appear once a week (most of the time), on their web site, but it does not seem to make it to the usual web sites.
29) Message boards : Number crunching : New tasks? (Message 2051) Posted 30 Mar 2023 by Jean-David Beyer Post: I too am a new participant at Denis@home. In my experience, I usually get one big rush of tasks a week, although this week I have gotten two rushes. It is not my highest priority project, but my system is set up to process up to 4 Denis tasks at a time (while running other processes at the same time, for a total of 12 processes at a time). On my machine, each DENIS task takes about 65 tp 70 minutes to complete. (My most important projects are World Community Grid that has been essentially down for over a year, and ClimatePrediction that has not sent out any work in over a month and their web site has a security certificate problem the last few days, so you will frustrate yourself if you try to deal with them.)
30) Questions and Answers : Preferences : Crunch only one project at a time (Message 2047) Posted 20 Mar 2023 by Jean-David Beyer Post: In the boinc manager, there is an option Switch between tasks every .... minutes. Mine is set to 1187.00 Depending on your needs, setting it higher than my short day might help.
31) Message boards : Number crunching : Invalid task (Message 2040) Posted 11 Mar 2023 by Jean-David Beyer Post: Hi [Jean-]David. It is in our side. The difference is really small, with this information I will review what is happening to try to improve. We have very few invalid simulations, to find them help us a lot. Two more have failed (and 202 valid ones). So less than 1%. Do you want me to send more as they come up?
