As you say Linux is quite resilient but presumable if there is a problem it should be possible to get it logged somewhere?Tom te tom te tomI don't think I missed the point - perhaps I was a little vague though, my apologies. When you don't need the processing power, F@H will be utilising at least one of your CPU cores to 100% (depending on how you set it up), performing large scale iterative calculations - day to day computing just doesn't use your CPU like this. If your CPU computes one wrong value in a desktop program you may never know about it, although it might crash eventually - in an iterative calculation it will invalidate everything which follows.
And I'm not making myself clear.Its a one core steam driven machine. With F@h running the machine always uses 100% cpu. So cpuburn/prime etc dont work the machine any harder.
Only f@h seems to go wrong: So 1) I get a lot of duff fah runs..or 2) there is a problem that doesnt seem to affect any other program so either the programs, or the kernel fix the problem and move on.
If its 2 then either f@h has a small problem (not likely) or I should be able to get the kernel to log the problem for me How do I do this sensibly - I dont want to know every step it takes just the bit where it does something to 'correct' an error - if indeed it has?
