3) Message boards : Number crunching : Request to cancel tasks (Message 51952) Posted 14 May 2015 by ScienceBlog.at Post: Dear admins, after a mail that my version would lead to premature termination of tasks I did an upgrade. This yielded �computation errors� and termination of the active tasks at the client. But seemingly, the server did not recognise this situation (I tried �update� and �reset� of the project), and the tasks are still �in progress� on the website. As the deadlines are not before March 2016, I'd suggest to cancel the following tasks (and delete this post afterwards), as there is no result to be expected from them: http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=18307888 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=18307886 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=18303368 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=18075315 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/result.php?resultid=18072419 (This corresponds to the following work unit IDs: http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9672844 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9678373 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9674126 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9678983 http://climateapps2.oerc.ox.ac.uk/cpdnboinc/workunit.php?wuid=9676131) Regards from Vienna/Austria Matthew
4) Questions and Answers : Getting started : Q. concerning duration (Message 49154) Posted 18 May 2014 by ScienceBlog.at Post: Hi, mo.v, you just bought them the chance to get a result: as this host has quite some RAM, the �leave in memory� option is actually activated (and has been all the time). So I'll let things run and see what happens. Thanks for the explanation! Cheers Matthew
5) Questions and Answers : Getting started : Q. concerning duration (Message 49150) Posted 18 May 2014 by ScienceBlog.at Post: Thanks, Les, this explains it, of course! But, then, I've got another question: will a result be of use to anyone or are they ignored anyway? In the former case I'd let those PM2 tasks have their chance of getting completed, in the latter I'd � just as you suggest � abort them and deselect them in the preferences. M.
6) Questions and Answers : Getting started : Q. concerning duration (Message 49146) Posted 18 May 2014 by ScienceBlog.at Post: Hello, world! We're running BOINC 7.0.27 on a debian 6.0.9 box with 2 Xeon E5450 CPUs (which gives a total of 8 cores @3GHz each). We participate in HadAM3PEU (as this is, where we are) and HadAM3PM2 (as it is �Unix-only�, and there don't seem to be too many Unix-boxes out there). The time estimate for a EU-task is roughly 120hrs when it starts, and after 22 hrs 16% of the job are done, which works out to some 140hrs � just like the estimate said. But: the Global Moses II tasks start at 150hrs and after 18:30hrs only 0.300% are done, which yields a total runtime of something like 6000hrs. The computer running the models is a 24x7 server, so this doesn't pose a problem by itself, but my question is if it makes sense to run such long tasks on a CPU? Or would you rather aborted those long-runners and leave them to be tackled by GPUs? Thanks for your opinions, Cheers from Vienna/Austria Matthew
