1) Questions and Answers : Windows : HADCM3 6.04 "to Completion time" increases each day? (Message 39392) Posted 27 Mar 2010 by old_user122149 Post: This thread is about the long (80/160 year) models. These are no longer available. The ones that you\'re crunching only take about 4 days, and the time to completion is fairly accurate. Yah, not true - it said 100 odd hours to start with and with a deadline of 1 year in the future. Nearly completed it - but at 336 minutes so far I think you\'ll agree that the estimate was wildly off, coupled with the non informatory (being generous here) deadline, this \'estimation\' of time involved is not FAIRLY ACCURATE. The factor of inaccuracy is ~3.3. This crap exceeds my tolerance levels and once this wu gets done i will downrate this project. I guess you can state categorically that the CP WU completion estimates actually use the hosts benchmark resutls? If so - it needs correcting. if not then to call it an estimate is bordering on the deceptive. Plus this boinc client is straight taking the piss: I got to the last \'26mins\' of the CP wU and boinc decides to download a WU from another project - fine - howerver it then runs the WU. Furthermore after that one is complete is downloads an additional WU ..and starts running that. (and it does not even bother clearing the completed wu from the screen) Good day.

(Message 38924) Posted 17 Feb 2010 by old_user122149 Post: can the initial estimate be fixed a little or the running to completion be corrected quicker please? So the only accurate measurement is the time elapsed? (not the percent complete or time till completion) First time I have started a CP workunit for some time now and I had to come here to find out what the issue was.
3) Questions and Answers : Windows : time to finish seems to not really change now. (Message 31240) Posted 1 Nov 2007 by old_user122149 Post: Good point re the ability to see my vital stats as it were on the website. I run all the various projects I am signed up for since not all have work, and some I have retired eg seti/primegrid since they are not what I want to do now. 12 projects in all: six are ot of work four have work (inc CP) 2 are disabled so CP does get deferred some of the time. I have set my comp to use shorter CP WUs now in the settings so the next ones will not be notionaly vexatios to me. My comp does crash now and then - but backing up the work is currently of no interest to me - although I do see the strong argument for the need for it in the case of CP especially in the case of these long WUs. I will very definitly look into changing the \'switch projects\' timer from 120minutes to a new optimal value, going from your suggestions. This is probably the answer to the issue. A side point is the data on old WU\'s in CP, looking through the older ones I participated on it seems the data about them has been reduced somewhat - so that it looks like some data has been lost. Many thanks for your responses and help.

Dual AMD 1.2 ghz processors. 31/10/2007 16:22:02\|\| Number of CPUs: 2 31/10/2007 16:22:02\|\| 1119 floating point MIPS (Whetstone) per CPU 31/10/2007 16:22:02\|\| 1842 integer MIPS (Dhrystone) per CPU PS it would be useful if BOINC would allow the following: a) copy and paste of a line from the tasks list. b) have a copy and paste screen for the computer details and bench marks... I seem to remember that originally the time to completeion was around the 2700- 3000 mark when I got the workunit in the first place.
6) Questions and Answers : Windows : Managing Disk Space Usage - a question (Message 22709) Posted 10 May 2006 by old_user122149 Post: I am up to 1.51 gig disk usage now after one or two more failed work units. (It seem a little optimistic to expect no failure in workunits running for 2400+ hours - probability of failure is high - is there a thread about why work units are not broken down (optionally) into smaller sizes?) Can I/Should I delete all the folders in the CP directory that have a different name from the current workunit being crunched?
7) Questions and Answers : Windows : Managing Disk Space Usage - a question (Message 22320) Posted 23 Apr 2006 by old_user122149 Post: not to put too finer point on it but why does the Climate prediction boinc project not clear up after its self?!?!? I have 618mb in two folders that are for failed/errored climate prediction work units. My disk space is being wasted. Is this an issue that is being looked into?
