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 from project websites and calculate per CPU the system RAC (Recent Average Credit) and earnings for all whitelisted BOINC projects.
Enigma@home
In this eleventh episode I am presenting an overview of 750 CPUs and calculated RAC for Enigma@home. I have only included those CPUs for which I have gathered sufficient information based on sample set of 3,775 hosts and 2,100,000 work-units.
Info on Github
Due to the large number of CPUs, I have stored the output separately on Github. The main file can be downloaded in Excel format or OpenDocument format.
The first worksheet in the file contains Gridcoin earnings per CPU for all projects. The snapshot below provides an example of this worksheet:
Other worksheets in the same file contain the details per project. I will continue to update the GRC earnings so it is best to download the latest version from Github.
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

If you notice any mistakes, for example number of cores per CPU, let me know and I will update the information accordingly.
