I want BOINC to write to a different hard drive because the one it's currently writing to is old (I think it's around 5 years old now). And I'm worried that with BOINC writing to it 480 times a day, it's going to fail sooner rather than later.
----------------------------------------I looked in the sticky thread and found this link http://boincfaq.mundayweb.com/index.php?view=292. But I think it's outdated because I don't have a cc_config.xml file in my BOINC directory. I'm currently running version 6.10.18. Any help will be appreciated. Thanks.

You can change the frequency of the checkpoints by going to the Advanced menu, selecting Preferences, clicking on the disk and memory tab and increasing the Tasks checkpoint disk at most every ____ seconds. I've got mine set to 1200. It means I might lose up to 20 minutes if my machine crashes, but I'm willing to deal with that.

I looked in the sticky thread and found this link http://boincfaq.mundayweb.com/index.php?view=292. But I think it's outdated because I don't have a cc_config.xml file in my BOINC directory. If you don't have a cc_confix.xml, you can simply create one, as described in the link.  Regards, Martin  |

I'm currently running version 6.10.18. Any help will be appreciated. Thanks. Hi, personatu, The FAQ is not outdated. You can do it with the same instructions but it's not very practical when having 6.10 where you can specify during the installation where the data_dir should be stored. You not having the cc_config,xml is because on windows installations the file is not created by default (on Linux it is). From that FAQ: First check if you already have a file called cc_config.xml; if you do not, make one with Notepad, make sure you save it as an All Files option, so it doesn't get the .txt extension. Also the WCG 6.2.28 skinned version creates the file by default for branding and corporate / large contributor reasons. The WCG client, when clean installed only tells there's a new version, when WCG endorses such a new version, on windows. As for client support, we now have to ask about 32 or 64 bit version since upgrading from one to the other has a snag, but in principle if not too attached to the cached work units it can be as quick with the 32 bit version as uninstalling and reinstalling and changing the data_dir location. Done in 60 seconds. Some screenshots found here: http://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,28971 piroque, the maximum for that WtD setting used to be 999 seconds. The default is 60 seconds Minimum interval if the science has one to write [1440 per day per core], so not sure where 480 writes came from... maybe the checkpoint FAQ discussing how often a science generates one, which is not all too frequent on several. 20 minutes is okay, unless you run an 4-8-12 core device. Then is seriously adds up, so I decided for 300 seconds (5 minutes). 20 minutes btw with some versions on a quad would only allow 1 write per 20 minutes, regardless of the number of threads... that would end up being one every 80 minutes :(. Fortunately after kicking some chin it was returned to a per core control... so far for a most superfluous history of BOINC.

I have UPSes and very few crashes, so I'm willing to deal with the consequences. |
