Posted 27 Jun 2015 by Matthias Lehmkuhl Post: Hi Eric, Get Decics with Bounded Discriminant v3.04 was also getting calculation errors, but I found also some finished/valid results.But the new one "Get Decics with Bounded Discriminant v3.05" is running good. No errors found. All results are valid.Could just check on one of my hosts the uploaded results. one additional point, the runtime of the 3.05 is nearly the same like the CPU time. one point regarding the temp files, why is there the problem? normally boinc apps should use the slot dir for temp files. In this case two running apps using the same temp file name should not get a conflict. one additional point, the runtime of the 3.05 is nearly the same like the CPU time. http://numberfields.asu.edu/NumberFields/result.php?resultid=11110368 but on 3.04 the runtime is twice of the CPU time http://numberfields.asu.edu/NumberFields/result.php?resultid=11143093 For me it looks like, the faster algorithm i not really faster related to the runtime. |

Posted 26 Jun 2015 by Matthias Lehmkuhl Post: looks like there is an issue on the "Get Decics with Bounded Discriminant v3.03" on one of my computers only one result finish OK, here is the good one http://numberfields.asu.edu/NumberFields/result.php?resultid=11107827 all other end in calculation error with different times sample result for calculation error http://numberfields.asu.edu/NumberFields/result.php?resultid=11107958 Host http://numberfields.asu.edu/NumberFields/results.php?hostid=22930&offset=0&show_names=0&state=0&appid=2 stderr is empty for that results with calculation error. CPU usage is less 50% for the last result (i've seen) and based on same on the other host http://numberfields.asu.edu/NumberFields/results.php?hostid=2794 |

Posted 23 Jun 2015 by Matthias Lehmkuhl Post: interesting, package http://numberfields.asu.edu/NumberFields/workunit.php?wuid=10081686 has a valid result with CPU time less 10000 seconds. My result hasn't finished after more than 2 days CPU time. The CPU performance is not so different based on boinc measurement. This looks strange to me. And the values in the "GetBoundedDecics_state" file of my result increase every minute. Today morning I had the following values: 0 -2 30 8 -62 13324144 0 13322140 0 241474 |

Posted 18 Jun 2015 by Matthias Lehmkuhl Post: I've two long running results for both the progress bar does not change since some days, I've recognized it yesterday. But the results checkpoint round every minute (the files "GetBoundedDecics_state" and "boinc_task_state.xml" are updated every minute) http://numberfields.asu.edu/NumberFields/workunit.php?wuid=10081686 CPU time now: 26 hours at 38,37% (server deadline 19 Jun 2015, 12:34:13 UTC) http://numberfields.asu.edu/NumberFields/workunit.php?wuid=10094998 CPU time now: 19 hours at 35,95% (server deadline 21 Jun 2015, 9:58:28 UTC) can you extend the deadline on Server for my results, so no one else gets this results? Or should I abort this results on my host? |

Posted 23 Mar 2012 by Matthias Lehmkuhl Post: Hi Eric, can you extend the deadline for this result? It's running since 3 Days, and now at 79%. I have to shut down the machine for 3 Days during a power outage over the weekend. http://numberfields.asu.edu/NumberFields/result.php?resultid=887424 Regular deadline is 24 Mar 2012 | 2:21:10 UTC Time to go 19 hours. Thanks. |
