In the past months I noticed regular requests from Gridcoin team members on Steemit, looking for the RAC output of their system 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.
Amicable Numbers
In this episode I’m presenting an overview of 1000+ CPUs with the calculated RAC and daily earnings for Amicable Numbers. Similar to previous episodes, I have only included those CPUs for which I have gathered sufficient information based on sample set of almost 14,700 hosts and 1,300,000 work-units.
After reviewing 17 whitelisted Gridcoin projects, Amicable Numbers is currently on position 14 and is a low earning project. On the other hand, the average RAC scoring is the highest of all projects in the list.
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 20: CPU calculated RAC and GRC earnings per project
- Worksheet 21: Threads per CPU
- Worksheet 22: 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 298 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
