MilkyWay@Home - Calculated RAC for CPUs
After a break of a few weeks, where I have been gathering further data for the final few whitelisted Gridcoin projects, I’m continuing the series with the next project for which I have prepared the calculated RAC (Recent Average Credit) and potential earnings for CPUs.
MilkyWay@home
In this episode I’m presenting an overview of 1300+ CPU types with the calculated RAC and daily earnings for MilkyWay@home. Similar to previous episodes, I have only included those CPUs for which I have gathered sufficient information based on sample set of almost 21,000 hosts and 1,200,000 work-units.
After reviewing 18 whitelisted Gridcoin projects, MilkyWay@home is currently on position 17 and one of the lowest earning projects for CPUs. This is not surprising as the project also supports GPUs.
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 21: CPU calculated RAC and GRC earnings per project
- Worksheet 22: Threads per CPU
- Worksheet 23: 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
