okay, now it makes more sense the longer I look at it. The difference can also be due to the higher number of threads of the AMD CPUs.
For my project, I would like to read out the date and the cpu-time I used for a task from each project. Do you have an idea on how I could extract that data from the project homepages?
Assuming you are solo mining:
go to your account page, then to hosts, then find the computer you are looking for based on its configuration and click on tasks. This will bring up a table of all tasks you have been sent as well as the status and how long they took to complete.
If you are in the pool you need to look up the pools stats and find your computer in the list and there will be the option to view its tasks.
you can also read the average time to complete a task from the /stats/host.gz file
yeah, I know that I could do it manually. But my CPU does 32 Tasks at once, so something between 200-1000 Tasks a day. Typing all of that into a txt file would pretty much be impossible.
