Here's one model I'm curious about (getting very cold). Let's see how it develops: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=12000683 Another note, this w series seems to run much slower (.55 v .48. on my machine). Forum search Site search |

From a post by Hiro on the beta site: On the main site, we have just started famous_w series of experiment using the same version of Famous. and later: To add a bit of background, we started using 2 sweep dynamics to stabilize the model. This effectively make the time step of the atmospheric _dynamics_ by half. However, the run speed hardly increases because the atmospheric dynamics (excluding what we call "physics" and radiative transfer) is a very small in term of CPU time. I think that the 2nd post also refers to the "w" series models. Backups: Here |

I had missed this cold failure: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=11997733 And this cold mode l is still running: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=12000683 Forum search Site search |

Famous_ kHz_1999_200_006712331_3 completed successfully. OS is Windows 7 64 bit SP1 RC running on a Core 2 Duo 2.2 GHz processor with 4 GB of RAM. A very warm one. Average temp. rising steadily throughout the 21th and 22nd centuries from 17.2 to 22.9 degrees C. Rise is greatest in the Northern Hemisphere were it top out at 24.4C. Solar constant is at default. |

In the famous_w0xx_599 series, I've had two fail and one succeed, so far. One of the failures was a runaway, reaching 38.5 Celsius before crashing. The other was a cold world, crashing at 8.7 C. The one that succeeded had quite extreme-looking values for ice fall speed, entrainment coefficient, and temp range of ice albedo variation. You just can't tell. Back on "v series" famouses now - the luck of the draw. |

Had a big crash (6 models) 12 days ago, due to disk issues (bad sectors). Early symptom: McAfee check took ages to complete. I eventually noticed all the disk error messages in Event Viewer. This solution should work some time: Have chkdsk identify the bad sectors once in a while (second checkbox). The new batch has been successful, except for: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=12400747 I hadn't met the error before. Some links below for everybody's information: http://ncas-cms.nerc.ac.uk/trac/UMHelpdesk/ticket/399 http://cpdnbeta.oerc.ox.ac.uk/forum_thread.php?id=229 Happy crunching for 2011.

Mavau and others who get a Model crashed: REPLANCA: PP HEADERS ON ANCILLARY FILE DO NOT MATCH error message: This is caused by one of the auxiliary files not having sufficient data to cover the full modelling period. Those data sets still in the queue that were affected have now been removed. Apologies for the mix up. Also, Kraken has filled up yet again, and data needs to be moved off to storage. Milo is not available to do this, so we wait in hope. :) Backups: Here |

I have a Macbook Air (1114220) that's been crunching since the middle of December. It's received nothing but FAMOUS models, and has completed 6 successfully out of 48 downloaded. I haven't checked them all, but the ones I have looked at state "INVALID THETA DETECTED". My impression from a search of the boards is that Famous models are reasonably prone to fail, but the percentage on this machine seems way too high. My question is, is there a way to conveniently exclude this machine from receiving Famous models, and if there is, should I do so? Of the 6 PCs I have on the project, this one is far and away the most "productive", when measured by credits received - over the last 5 days it's averaged 2,308.42 credits (1,154.21 per CPU core). My 2 Quad core Windows machines averaged 550 and 599 per core over the same period. The other two Core2 Duo machines (both Windows boxes) managed slightly less. Derrick Ashby |

Yes, you can exclude the Air from getting Famouses. To do so: (1) Go into "Your account" - see the blue menu on the left. (2). Scroll down to "computers", go into this, and then into "Details" for the Air. Set the Air to be in a different 'Location' from your other computers -- say, School. (3) Back on the "Your account" page, go into "climateprediction.net preferences". Find the link for "Add preferences for School", and in there, select the applications that you want to allow, and de-select "accept work from other applications?" ------------ The reason for high daily credit and famouses failing so frequently on Macs is that the CPDN programmers could not get the Famous application to compile without extra optimizations. The result is that Famouses run very fast but also crash more often on Macs than on other platforms. HTH |

Unfortunately Famous is currently the only model type available for Mac and Linux, so if you exclude Famous you will get no work at all. |

64bit linux on dual core Intel 10 errored out all together, 2 probably due to reboot issues. 2 are 599 models which are known to be more prone to crashing. u4pe1999 74gg999 ugyf1799 v3pc1899 vhcx1199 vizg1599 vizh1799 w56v599 w8y4599 w158599 Some invalid theta the rest negative pressure values. Completed. v3cz1799 v1b01799 va9x1799 ubdw1999 uh8d1799 which makes 5 or 1/3 completed. On my partners box winxp amd. vnt18199, the only famous unit started completed. |
