Crash recovery: my 1wk-old backup or more recent .zip uploads?
(Message 35187)
Posted 6 Oct 2008 by JimMcCarthy_StellarSolns Post: Computer ID 903841 is one I have at the University where I teach once per week. Apparently it experienced a compute error early this morning. I\'ve captured the BOINC work directory in the state I found it this afternoon (post error). My last WinZIP backup was 1 week ago, so I\'ve restored the work directory using that archive and am resuming work from that point (1-week ago). But from the message log, I see that some .zip file(s) of intermediate results were uploaded to CPDN more recently -- a few days ago. Is it possible to resume work from the point-in-time when those intermediate results were uploaded (a few days ago), or do I need to restart from my last WinZIP backup (1-week ago) ? Thanks, -- Jim |

Posted 15 Sep 2008 by JimMcCarthy_StellarSolns Post: Hi Les -- Thanks for the rapid reply. Yes, I know the clock is way off -- I need to run out and buy a replacement CR2032 3V battery for the motherboard, or remember to set time from the command line after booting this machine. I did the latter on an earlier attempt to start a CPDN project from this computer last week (and had no better luck then), due I\'m sure to the second problem you identified.
It says \"i686-pc-linux-gnu\" ... but I seem to recall reading elsewhere in the CPDN forums that the project will now give 64-bit tasks to machines running 64-bit BOINC clients. Is that true only for Windows (not for Linux) ? Granted my \"ia64\" Itanium-2 architecture differs from the more commonplace \"x64\" EM64T architecture, so even if 64-bit tasks are available for Linux x64, those still may not be applicable to this ia64 machine of mine. From the URL you linked to above, I followed the link \"download from a third party site\" and from there the first 3rd party site (run by Lars Bausch) has the glibc v2.3 compatible programs boinc_client and boinc_cmd. I gather the prolem is not simply the \"name\" of my Linux install.... - - - If I can install and run an \"i686\" (32-bit) BOINC client for Linux using the IA-32 Execution Layer which enables Itanium-2 machines to run 32-bit applications, am I still likely to encounter problems with the \"name\" of my Linux install ? One way to find out is to try it, I suppose ... I\'ll do just that sometime this week, and report back. Thanks again, -- Jim |

Posted 14 Sep 2008 by JimMcCarthy_StellarSolns Post: From the Berkeley BOINC site, I downloaded the 64-bit boinc_client and boinc_cmd programs for my Linux architecture (ia64).
