this is the 2nd time that error computing occurs with hadam3p on resuming task at start when 25% -30% work is done Sam 15 aoû 09:46:52 2009 climateprediction.net task hadam3p_nh55_1973_2_006240307_3 resumed by user Sam 15 aoû 09:46:53 2009 climateprediction.net Restarting task hadam3p_nh55_1973_2_006240307_3 using hadam3p version 608 Sam 15 aoû 09:46:55 2009 climateprediction.net Computation for task hadam3p_nh55_1973_2_006240307_3 finished Sam 15 aoû 09:46:55 2009 climateprediction.net Output file hadam3p_nh55_1973_2_006240307_3_1.zip for task hadam3p_nh55_1973_2_006240307_3 absent Sam 15 aoû 09:46:55 2009 climateprediction.net Output file hadam3p_nh55_1973_2_006240307_3_2.zip for task hadam3p_nh55_1973_2_006240307_3 absent Sam 15 aoû 09:46:55 2009 climateprediction.net Output file hadam3p_nh55_1973_2_006240307_3_3.zip for task hadam3p_nh55_1973_2_006240307_3 absent |

The error message for that task is described in the BOINC FAQ here. It recommends a memory test: if that passes then post back here again. |

Iain I think that BOINC FAQ refers to PC (Windows) problems and the downloads available would not be of any use to a Mac user. Keith [P.S. Sorry. Found after reading further info re Shared memory as follows in the BOINC FAQ:-- ========== A better solution is available—if you don’t mind reconfiguring your system’s kernel a little. The method, accompanied by a more detailed description of the issue, is outlined in Configuring Shared Memory on Mac OS X from Spy Hill Research (hosts of the BOINC Pirates@home project). It involves creating a text file “/etc/sysctl.conf†that contains the following commands: kern.sysv.shmmax=16777216 kern.sysv.shmmin=1 kern.sysv.shmmni=128 kern.sysv.shmseg=32 kern.sysv.shmall=4096 and rebooting the computer. This will quadruple the default allocation of shared memory. Note that the problem may manifest with slightly different error messages: “Can\'t create shared memory: system shmat†followed by “Couldn\'t start or resume: -146â€. ========== That has been mentioned before regarding running HADCM3 on Macs.Is it possible to create this file in TextEdit (or does it require special software to create it). And where should this file be placed? Keith ] |

I think that BOINC FAQ refers to PC (Windows) problems and the downloads available would not be of any use to a Mac user. Indeed so, but there are Mac versions - just google \"mac memtest\". Does the shared memory problem cause a 193 stop? If so, perhaps we need to update the readme files, which still mention \'fixing error code 6\' but make no mention of 193. BOINC versions increment and may well cause errors to present in different ways. |

If you\'re referring to the messages in your original post, that isn\'t a problem. These models only create zips, (3 of them), at the end of the modelling, so what the message is saying is that BOINC couldn\'t find them, which is obvious to people, but not BOINC. If the model hasn\'t reached the point where they get created, then they won\'t be there. When a data set is downloaded, part of this a list of the files that BOINC should expect, and where to upload them. It doesn\'t say WHEN they get created, and normally this wouldn\'t matter. It only matters when the model fails, which causes BOINC to look at it\'s to-do list. Backups: Here |
