Post: Just a side note, I usually allow new tasks when I am down to the last few hours of the models so that HOPEFULLY a new model will be downloaded right after the old model completes. Not YMMV depending on what else is going on with BOINC ... like how many projects you have loaded and running on the system besides CPDN (if any) ... |

How can I limit climateprediction to run only one task at a time?

Post: It depends what you want to do with the other core(s). Follow md3\'s advice if you want to keep the other core(s) idle. THen the key is to get one model from CPDN., if you get two, kill one of them .... or suspend it. As for the test of it, then select resource shares as appropriate. Mine is more complex, but bear with me. I have 8 cores and insatiable desire to run projects. SO, I set resource shares from 12/14 through 100. I select up to 4 pojects with a share of 100 ... these will run continually on one core. In other words, I should see, in general, one task in work at all times for each project (variations in timing and oddities can cause slight bobbles and cases where this is not ALWAYS true, but it is rare). Should I want to put emphasis, I might have one at 100, and another at 300 where I would normally have 3/1 tasks running .... Four more projects get shares of 50, thus occuppying two other processors. so, half the time I should see work from one project and half the time the other ... Four more projects should get shares of 25 meaining ... I should see them rotate about a quarter of the time ... The last projects I give 6 share of 12 and two a share of 14 .... I see them once a day maybe slightly more ... And so, for example, I am trying to finish a CPDN task so CPDN is share 100 and runs all the time, as does M-Way and Malaria (225, so I have two and sometimes 3 in work) and SIMAP ... the rest of the projects get tailored shares ... as long as the number adds up to 800, I have a proper allocation of time ... With two cores, add to 200 ... though rememvber, with one task and a share of 200 for CPDN will not make it run on two CPUs. |

Post: Les offered this advice ... Set to one core, allow CPDN to d/l the one task ... then set NNT as Richard noted, and set the cores to run as you desire. I have the same thought and suggested that CPDN add a preference to the site to allow us to have the scheduler be advised as to how many tasks we wish to DL, regardless of the number of cores. So far, to no avail. At least it seems that I am not the only one that would like this feature. In fact, I would bet that many are dismayed at getting 2 or more tasks that last for weeks/months and hate the thought of having them around that long, and hate eqaully the thought of killing the task for convenience sake... Anyway, hope this all helps ... I have 2, just down from 3, tasks on my 8 core and when I can run the CPDN model again, one should complete in another 3 full days of running ... then I will be back to the singleton I wanted in the first place ... |

Post: The \"nothing going on\" at the end of model is all of the post-processing of the many data files. It can take 10 minutes or more, depending on processor speed. It was \"tempting\" to intervene ... but, I called up the graphics and it said POST Processing ... so, I waited ... Anyway, one down ... one more in work and then back to the long model ... THEN, if I am going to stay BOINCing, we shall see about another model ... Still think we should have a setting on the prefs page to say only download one model (though some overlap late phase 3 would be Ok, but, I should not have to do gymnastics to try to keep from getting three models that clutter up my lists for months at a time ... Anyway, that is for later ... |

Post: Back on topic ... The first of the two slab models completed this morning and though the last few moments of 100% and nothing was seemingly going on was worrisome, all is well with patience. Zipped up the model and uploaded, reported and marked as valid .... So, good work team ... (Go team! Go! Rah! Rah!) and I let the second model off the leash and it is running as we speak and has a couple more hours on its clock (now 11:11 with 173:47:20 to go) ... and as I change my processing priorities as another project has come close to initial target I am working down my work queue for it and starting to build up the work queue for the other project ... All seems to be semi-well in Paul\'s world ... |

Post: Nobody will ever accuse you of getting too many credits from CPDN. In some ways CPDN ought to be the cross-project benchmark. When CPDN joined BOINC, as far as I know the credit level was aligned with Seti. The CPDN level has to my knowledge never changed except that credits for the current optimised HADCMs were raised by 20% because they run 20% slower. Or approx those percentages. There is a spreadsheet that embodies a concept that I proposed to do this very thing ... it uses computers that are attached to multiple projects to show the \"earnings\" rate ratio between the projects ... I had proposed a somewhat similar system with the use of inter-project linkages to allow the normalization of awards. In a sense, it built on the idea of calibrating computers and then using those to establish the productivity ... in that we do have a variety of computer multiple computers will have to be used and this will be by no means perfect ... The problem is that it will require a cross-project coordination that is still lacking ... one of my other pet \"themes\" that many seem to be tired of hearing about ... In my two year \"vacation\" I would have thought that some progress would have been made on some of the issues I was pointing to back then, yet on my return I find not status quo, but a more hostile and even less coordinated environment ... I see strong evidence that many projects, particularly the new ones are running into the same problems that older projects have already faced and the same questions are asked and answered and no one is writing it down ... not even that nut Paul D. Buck ... what ever happened to that crazy guy ... |

Post: Mo, Um, I think I did call them up ... hard to say for sure ... I was kind of trying v 6 on a whim, and actually have gone back and forth from 5 to 6 and back to 5 a couple times with no problems ... that of course does not mean others will not have problems ( I had to install twice on one windows machine, but did not lose any work their either). The only oddity is that if I launch the graphics on OS-X I wind up with a window in the Dock that won\'t go away until I stop BOINC and the process running the model (for all projects) is killed. ONe of the reasons I don\'t often call up the graphics ... As far as alpha testing v6 I did it on another system for over a week and had no problems so I thought I would give it a whirl on the Mac ... aside from the connection issue I saw no difference, or improvement for that matter with v6 so don\'t have any objection to 5.10.x for the time being. It is just that if I see a problem I can no more NOT report it than I can give up breathing ... though I know as a kid I did try THAT a couple of times ... Anyway, the no problems was on the Mac Pro version ... for once the Mac was ahead of the windows version? :) And the only time I run CPDN without NNW set is when I need another model ... though I wish you had a setting to make sure I only got one ... even with my settings to .1 or .2 day the last time I got two models ... Which means I have three lined up ... sigh ... well, one has only a day and a half to run so I can put the other slab on next and that should run off in about a week ... 180 hours to go on that one ... then the coupled model will take me a couple days more .... |

Post: I think your 8-core Mac will be getting more than 5000 credits per day. It is likely to be above 4,000 I agree on that. It is kinda hard to say for sure as I am, and have been, moving about quite a bit. Right now I think I have about 9 projects with active and continual tasks on it .. But, I have found at least one project MilkyWay@Home that seems not to be running as fast as it should, but, I have mentioned this on their boards and with luck they will figure out what is the issue ... because of this \'butter-fly\" of mine it will be hard to tell for sure ... The other complication is the cross-project credit thingie ... I better stop here as I usually get into trouble when I go on ... :) |

Post: If you\'re talking about 64 OS for Macs, that\'s correct. Um, it is the same computer ... happily running the same model and the only thing that changed was that I installed 6.1.x over 5.10.45 ... With 5.10.45 reinstalled I have not seen a trickle up yet and a forced Update did not create one ... so I am waiting for it to get to the next one :\"naturally\", which i hope will be soon ... I should be in phase 3 already and am at 74% something done ... with 42 hours to go ... For whatever reason, version 6 of BOINC reports the Mac Pro differently even though it works ... For what it is worth, Sztaki has the same problem ... works fine with 5.10.45 but not with 6.1.x ... after reinstall: Thu Apr 24 12:28:02 2008||Platform changed from x86_64-apple-darwin to i686-apple-darwin |

Post: The problem is that the backup I am using TimeMachine is not very configurable and I have little use for 10,000 copies of transient data ... so, I have excluded the folder ... The machine is \"stock\" in the sense that I did not alter the configuration and set-up other than to install additional parts. For one, I added memory to fully fill the two riser cards with 16G of all matched memory sticks ... I added 1TB drives which I made into a RAID 5 array using the RAID card from Apple ... Other than that, it is a stock system ... :) But, my understanding is that the memory bus is slightly differnent somehow as that was the question the folks at Micromat asked when TechTool 4 would not boot from the CD ... I think the one machine is doing about 4-5,000 CS per day ... it is hard for me to say exactly as I have been playing with projects too much to be able to isolate the effects easily ... Though, if I can get the second Dell dual Xeon back (my brother said he would ship it this week) I may put both of those machines on just one or two PC only projects for a few days to a week to catch them up, and if that proves interesting I may wait for the daily numbers to \"settle\" and from there will be able to have an idea of what it can do ... I am slowly putting my projects into the resource shares I have been planning as I work a project up to its initial target, then I move it to its target share (12 or 14 to 100) allowing me to run as many as 20 project on the one machine with actual CPU allocation from 1.5% to 12.5% ... Like right now I am concentrating on NQueens and Sztaki which have shares of 200 and 348 while I have other project in their allocation slots now ... for instance CPDN should get half a processor each day for working ... though I may raise that until I can clear the models out ... |

Post: The CPDN scientists are doing plenty with the raw material we provide: Well, a) the key word is most, there are 58+ projects that I have on my little list and 10 projects have published one paper or more ... that is 20%, most fits the bill ... b) Some of those papers are over 5 years old, half of those that published, published only one paper ... Eah shows two, but it is a draft and final ... c) I did not say CPDN was guilty in this respect. d) notice where most of my effort has gone historically ... to CPDN ... which, as a project has done more ... Note: SaH is high for historical reasons in that at one point they were the main project that had work all the time ... but you can also see on the stat sites where my ranking there is dropping like a stone ... I do one or two tasks a week for them and that is all ... almost all of my attention is elsewhere ... WCG is about to get a whole lot more of my attention again as I turn to and get more of the minor projects at their targets ... Sorry if you misconstrued my comment ... |

Yeah, so I had to change the project selection around a bit ... CPDN is a little long for this computer, especially in that I don\'t know that I will keep it running very long ... BUt, it seems to do M-Way nicely along with a couple other projects ... so I will pick and choose a few to keep it busy and my scores high ... After all, since most of the projects don\'t seem to be doing much with the work we do for them, it [bMUST[/b] be about the credits .... :) |

Post: You taught me a lot Paul (even if you don\'t know it). Well, I know it NOW ... :) My one professional passion is for teaching... I CAN teach, but I don\'t do well with the nonesense that comes along with it ... But, for all of us it is a continual learning process ... Yesterday and today I learned how to install Ubuntu and stand up a system for Linux (never really did if before with intent to use it) and I even have BOINC running there ... Still trying to figure things out ... I lost my cable modem connection and Ubuntu then decided I did not have a network card and it was only when I moved the card from one slot to another that it would find it and connect to the network again ... not sure what is up with that ... It is a REALLY old AMD system in which I stuck a 16G HD ... well, it works anyway ... But I see Linux systems still under-claim on credit ... Oh well ... |
