On these projects, are there sometimes problematic work units?
The last two units my machine's tried to crack have slowed to a crawl. I don't thing 'time remaining' is supposed to go up, is it? 1 hour left to go, then 11, then 19....
Plus, it slows down every other program I try to run on the machine.
I was hoping it was just a bad unit, but two in a row makes me a teensy bit anxious about my settings.
Like any computerized number crunching matrices are manipulated. The more memory and/or the more threads (cores=CPUs) available the more rapid the processing. If you have only limited ram, say your OS takes up a bunch of RAM for speed of processing, and only a single CPU (not dual core, quad core, 6 core or eight core) before you need to start swapping with disk for processing you will find impacts almost immediately. Perhaps if you reconfigure the thresholds upon which your machine requires you go to disk memory access for real time processing can make the problems smaller. You can find leads at the Wiki Folding site.
Just noodling.
As for percent done and time to complete jumps the processes are guided by an algorithm which can be impacted by outcomes of any folding iteration. One of mind went from three hours estimate to complete at 10% to 11 hours at 13%. Kind of like a path was being followed until it ran into a hurdle so the processing went back and tried another path or two.
