It has been almost a week since I started the CPU-project comparison. I started out with 15 projects of which one had to be cancelled now due to computation errors. BOINC does a good job at fetching work for a project for ~12h, finishing that and then moving on to the next project in a circular manner.
This data is to be taken with a grain of salt. As I mentioned, it is important which project just had its turn as I estimate that this will make a difference of up to 1/3 of the magnitude. It has to be mentioned that the projects have not confirmed all of my tasks immediately (Citizen science grid for example) and therefore have a delay in their mag.
Furthermore, magnitude builds up in a period over 5 weeks. I expect the data to become more relevant at that time, since the fluctuations should also be reduced to a smaller percentage of the total magnitude. Single computational errors won't affect the data then as much anymore as they do now.
I plan on making some graphs for the future, as they just always look cooler :) With one datapoint per project , however, they would not make too much sense.
Same shout-out again: If anyone has an Idea on how I could extract the data about CPU-time from the project websites, it would be great to get in touch!
