I have a quad-core laptop that has not reported in a week. It was working on mapping cancer markers. All four work units were around 100 hours of elapsed time so I decided to reset the project and to not allow mcm units. That was a couple of days ago and it still has not completed a unit. It is now working on fight aids at home. I just looked at one unit for 5 minutes. During that time elapsed time increased by only 3 minutes and remaining only decreased by 9 seconds. It stated that only 21% progress but elapsed is 13 hrs 42 mins and remaining is 2 hrs 18 mins which looks like 14 hours out of 16 hours which is more like 87% progress. I do not get close to 24hrs times the number of cores even when I run the computer 24/7. It feels like I am getting credit for about 60% of my true CPU time. I do not think it is the computers fault since it runs other programs just fine. So which should I depend on? The progress figure or my calculation of elapsed time divided by the total of elapsed and remaining times?
