Rosetta@home - Calculated RAC for CPUs
In the past months I noticed regular requests from Gridcoin team members on Steemit, looking for the RAC output of their systems to determine which Gridcoin project to crunch.
This gave me the idea to gather information for all whitelisted BOINC projects and calculate per CPU the RAC (Recent Average Credit) and potential earnings.
Rosetta@home
In this episode I am presenting an overview of 1,550 CPUs with the calculated RAC and daily earnings for Rosetta@home. I have only included those CPUs for which I have gathered sufficient information based on sample set of 57,000+ hosts and 2,000,000+ work-units.
After reviewing 13 whitelisted projects, Rosetta@home is currently on position 10 and as such one of the lower earning projects for CPUs (see table below).
Info on Github
Due to the large number of CPUs and projects, I have stored the output separately on Github. The main file can be downloaded in Excel format or OpenDocument format.
The file contains the following worksheets:
- Worksheet 1: Average daily earnings per project
- Worksheet 2: Daily Gridcoin earnings per CPU for all projects
- Worksheet 3 to 15: CPU calculated RAC and GRC earnings per project
- Worksheet 15: Threads per CPU
- Worksheet 16: GRC per 1k RAC for each project
I will continue to update the file with more projects and refresh the earnings so it is best to download the latest version from Github.
Average daily earnings per project
In case you don’t know your CPU, you will likely achieve the maximum earnings for your system by selecting one of the first projects in table on the first worksheet (see also table above). Don’t confuse the numbers in the table with actual earnings, it is merely an index to compare the earnings potential between projects. Obviously, the project ranking will change when computing power is shifting across projects so I will continue to update the table to reflect this.
The ranking of projects is established in the following way:
- Select those CPUs which have results in all projects (this applies to 324 CPU types at the moment)
- With the selected CPU types calculate the average earnings for each project
- Sort the projects from highest to lowest average daily earnings
Calculated RAC
I used the following formula to calculate the system RAC:
Breakdown of the formula:
- Σ points of sample set, is the amount of points credited by the project for the returned results
- Σ time of sample set, is the total time it took to process all returned WUs
- Σ CPU threads, is the number of CPU cores x CPU threads.
Three assumptions as part of these calculations:
- Multithreading is enabled in the BIOS
- The calculated RAC is based on running one BOINC project, 24/7 on all cores
- The higher the number of gathered WUs per CPU, the more accurate the RAC value

Great post! I am sure this excel file will become the go-to place for all crunchers! Thank you so much for putting it together. I wonder how difficult it would be to have it as a webpage somewhere (maybe in the wiki?). Also, could you please include ODLK soon? I am very curious to see how it compares with the rest.
Thank you for your comments.
I'm thinking about it already and would like to make it more dynamic so that it will automatically updates based on new work-units.
Concerning ODLK, I expect to have the file ready in 2 weeks but I'm first releasing Cosmology@home. Besides, ODLK1 has only been whitelisted since a few months so I may not have enough work-units yet but I'll keep you're request in mind. As soon as there are enough work-units, I'll publish it right away.
