Hmmm, used an no longer used userid to post in here I see. Pity, I can\'t merge it with the one I\'m crunching with now.

Which is this one:

I made the changes to delay the shutdown of Vista, think it will stop some and cause others. Seems as if it depends on whare CPDN is when the shutdown occurs. To bad that CPDN will not just shut down and later restart from the last checkpoint all the time.


You could make a batch file to shutdown BOINC first and initiate Vista shutdown after that.

Why re-invent the wheel, here\'s a link to a message describing the process.

Add a bit of class to the shortcut by assigning it a custom icon. Right click the shortcut, click [Properties] and select the [Shortcut] tab. Click [Change Icon] and select from the icons that are displayed.

Tell her to use the shortcut to shutdown the computer

Post:
Malloc errors would not be related to BOINC settings, as CPDN requests memory from the OS, not BOINC. So, BOINC preferences should make no difference in this case.


if you mean CPDN requests memory from the OS when told by BOINC that it is allowed to ask for more memory, then I would approve of it. If CPDN completely ignores the user\'s prefences, that would be bad.

Sounds like you\'ve solved the problem, but yes, it\'s worthwhile doing the full test.


I\'ll certainly consider it very seriously. I suppose I can stand to lose 24 hours of crunching. ;)

I tested my Q6600 at the maximum power consumption/heat production setting. I\'d say the test with memtest86+ should have taken care of the memory testing.
For Climateprediction all my testing may have been too short but in my opinion it should have been enough for normal BOINC-usage. The core temeratures were acceptable, I think. About 60C at 100% load, for a \'normal\' 100% load about 50C to 55C.

I haven\'t had any problems with CPDN since reducing my overclock. Would you recommend more testing despite this? BTW, I\'m not crunching 24/7.

You didn\'t indicate how drastic your O/C is. How well does it play with 24 hours of Prime-95 (one copy per core)?


I had it clocked at something like 3.07 GHz, now it is at 3.0 GHz (stock 2.4 GHz). Hearing/reading about all the achieved overclocks on a Q6600, 3 GHz does not seem excessive to me.

I haven\'t run prime95 for 24 hours, only for something like 6 hours (on all 4 cores) and just one pass for memtest86+.

I have had that happen to me with 3 models in a row and not only with the SM ones but also with a CM model. Easing back on my overclock did seem to help. The jury is still out on that question, I haven\'t completed a model since lowering my overclock, but it is looking good.

You\'ve given me a lot of reading it seems. Thank you for that. ;)

When looking at the model I\'m currently crunching (It is at the early stages, 1940), I became curious how the global mean temperature compared to the actual global mean temperature for that period. I wanted to know that because it seems quite a bit different from other runs. In my searching I came across this article.

http://www.john-daly.com/ges/surftmp/surftemp.htm

It is 7 years old, do more recent observations invalidate the article? Are the questions raised in it about the accuracy of the data collected on earth valid at all?

I\'m asking this because the article suggests to me global warming is not much of an issue.

Backing up is not the real problem, I am as capable as anyone else if it comes to copying the BOINC folder to another location.
But I crunch for multiple projects, and restoring a backup without affecting other projects is not as simple as copying back the climate prediction folder. From the bit of reading I\'ve done it involves editing a number of files and selective copying. To be quite honest I can\'t be bothered to do that. So I\'ve stopped backing up and count myself lucky my last model crunched to completion without any problems. I think (hope) crashes are too infrequent for me to become proficient in the steps needed to restore a particular model.
Anyway, I also would like a simple program which can backup CPDN and restore a backup for me.
