1) Message boards : Number crunching : My stats page at BOINCstats/BAM is totally useless. (Message 50134) Posted 11 Sep 2014 by SandJ Post: It will take months to smooth out that erroneous -- and gigantic -- bump. I am not a happy camper. I enjoyed the competition I was having with some friends, but now, instead of having BOINCstats/BAM do the comparisons for us, especially with regard to recent average credit, we'd have to do the calculations by hand for my account. Unfortunately, that's too much work for a casual thing like this, and I have to drop out of the competition. So make it fun. Declare yourself "Ultra �ber-winner Of All Time 2014", change your .sig or whatever accordingly permanently, and generously announce you have bowed out of the competition so the lesser mortals stand a chance. ;-) I know it is annoying, but of all the shit that can happen on an 11th of September, this is possibly not the worst. After all, you might not have been given any credits at all for work done; now that does make my blood boil.
2) Message boards : Number crunching : Credit updates? (Message 50124) Posted 11 Sep 2014 by SandJ Post: Apparently, "China's Tianhe-2 supercomputer is the fastest in the world at 33.86 petaFLOPS, or 33.86 quadrillion floating point operations per second." Crikey, my PC's (erroneous) 2.13 sextillion floating-point operations sounded good until I worked out that Chinese supercomputer can do that for real in under 18 hours. :-( Still, I'm jolly glad I printed off my certificate last night, before they fixed the credits.
3) Message boards : Number crunching : A different upload problem -- out of disk space on rapid-watch.badc.rl.ac.uk (Message 47524) Posted 10 Nov 2013 by SandJ Post: I suppose, for a research project, having so many people round the world helping do your processing that you cannot handle all the incoming results, is a nice problem to have.

5) Message boards : Number crunching : Running out of time for a packet (Message 45907) Posted 12 Apr 2013 by SandJ Post: Thank you; that's a relief. When processing packets this size it feels to me I have taken on a voluntary responsibility and I have an obligation to see it through. ;-) I just hadn't expected the PC in question to plod along as slowly as it has. (The PC in question is my 2nd desktop PC. I have been wanting to replace the operating system from Ubuntu to Linux Mint for about 6 weeks now. The only thing stopping me is waiting for this data packet to finish! I did create a Mint partition and try to move the data packet but I couldn't work out how to get Boinc to recognise it. I did this once before in Windows but cannot work it out under Linux. Never mind, I've decided I'll wait.) Edit: Having re-read the Recommended System Requirements, I see why I have this feeling of commitment (it asks for it) and that the PC is just above minimum spec. Watching this packet is like owning a Tamagotchi :-)
6) Message boards : Number crunching : Running out of time for a packet (Message 45852) Posted 9 Apr 2013 by SandJ Post: I have a work unit processing which I think is going to time out before finishing. For a long time I thought it would complete within the deadline; I now can see it won't. http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=8407572 If it runs out of time: - will someone else have to process the same packet from scratch again? - is the 6 million CPU seconds wasted? - do I still get the WU credits? As far as I can make out, it has got further with this packet than the 4 wingmen did; is there any way to allow it to continue beyond the deadline? Is there a benefit in doing so?
7) Message boards : Number crunching : Packet failed at 100% (Message 45336) Posted 16 Dec 2012 by SandJ Post: As for "failed results", I suppose that you know that the purpose of this project is NOT to complete them? Ah, no, I hadn't picked up on that. I understood it was validating models, but did not realise 'Error while computing' equated to 'had enough of this model thank-you-very-much' for this project. I had just assumed it would terminate the work package tidily. Thank you.
8) Message boards : Number crunching : Packet failed at 100% (Message 45334) Posted 16 Dec 2012 by SandJ Post: I have been waiting for some weeks for a workunit to finish so when it failed at 100% my reaction veered between disappointment and anger. I see the same workunit 8398079 has also failed for someone else who is using a different operating system (Darwin v Xubuntu) and processor (Intel v AMD). I don't mind wasting a few hours on experiments but wasting WEEKS of processor time is very annoying. I reckon I've put about 20 kWh of electricity into this project to produce failed results. Should I give up on this project?
