FindTheMag helps optimize your BOINC client for Gridcoin mining. You can group BOINC projects into two groups: “preferred” projects and “mining” projects. Preferred projects are ones which you want to crunch regardless of how much GRC they get you. Mining projects are projects which you are willing to crunch, but only if they get you the maximum amount of GRC possible. In the event that your preferred project(s) happen to be the most efficient to mine, FindTheMag will assign all project weight to them.

FindTheMag uses your own BOINC client’s stats to determine which projects get the most credit per hour on your machine. It then figures out (using your Gridcoin wallet) which project gets you the most magnitude per hour. Quickmag is a similar tool which will estimate the most profitable projects for your hardware based on the performance of other crunchers with similar hardware. It’s useful and elegant. You should check it out.

This tool’s accuracy improves the longer you have been running BOINC. It will automatically set all Gridcoin-approved projects to a weight of one so they will continue to use .1% of your processing power, each time increasing the accuracy of the tool.

This tool requires that you have the Gridcoin wallet running on your machine and that it is fully synced. See FAQ for ways around this. The wallet doesn’t need any coins in it, just an up-to-date copy of the blockchain. It also requires python 3.8 or higher, though earlier versions may work they are unsupported. If you just installed BOINC, this tool takes about 48 hours to start working as we have to wait for projects to grant you credit for your work. Though really a week’s worth of data is about the minimum you’d need to get useful information from this tool.

If you use an account manager like BAM:

  • Put each host into its own host group
  • Assign weight to projects in the host group

If you manage your BOINC client locally:

  • There is no way to set project weight outside of logging in to each project manually and setting it there.
  • You can still use this tool to find out the mag/hr of various projects and “no new tasks” projects you have no interest in crunching either because of low mag/hr or because they are not your preferred projects. This can be done locally on your BOINC client.

If you are a pool miner:

  • I don’t know the best way to do this, I’ll gladly add step-by-step directions here if somebody can provide them. I would assume it works similarly to BAM.

If you do not have a minimum 1% sidestake setup to the Gridcoin foundation, this program will prompt you to set one up and refuse to run if you don’t. We should all be pitching in to help promote and improve a coin we all benefit from.

Quickstart instructions

For all platforms: Open the first few lines of the file in a text editor and change the settings you want.


  • Download the latest version of python from Enable the “install to system path” option while installing.
  • In command prompt, run the command python -m pip install --upgrade pip
  • In command prompt, run the command python install -r "C:\Users\user\Downloads\FindTheMag-master\requirements.txt" (or wherever you saved this tool)
  • Double-click on or run python "C:\path\to\" from command prompt. We suggest the second method as it will display errors if the program exits unexpectedly


  • Open a terminal and go to the folder you downloaded this tool into using cd /home/user/Downloads/FindTheMag or wherever you put it
  • Run pip3 install -r requirements.txt (Note that you need pip installed, if you don’t have it, you might need to run a sudo apt install python3-pip)
  • Run python3


  • Open a terminal and go to the folder you downloaded this tool into using cd "/home/user/Downloads/FindTheMag" or wherever you put it
  • Run pip3 install -r requirements.txt
  • Run python3


I’m not getting as many coins as I expect or I haven’t received my rewards?

Consult the official Gridcoin help channels, this tool just suggests project weights. If you are a solo miner, be sure you have enabled GDPR export on projects which require it. See

I’m getting some error while running the tool or need to contact you

My BOINC client doesn’t seem to be crunching according to the weight I assigned?

Changing your resource share doesn’t insure that your machine will immediately start crunching according to those resource shares, instead your BOINC client will gradually “catch up”. For example, let’s say you have a project which you have recently assigned a weight of “one” to while your other projects add up to 100. Even though 1 is a very small weight, if you have been crunching for six months and the project previously had a weight of zero, BOINC may fetch a bunch of work-units to catch up so that it will have crunched that amount of weight over that entire time period. So for that day, it may appear as if the project has a weight of 1000, but that’s because it’s average weight is still <1 and it needs to catch up.

How does it determine the most profitable project?

Each project assigns credit for your work, and BOINC keeps track of how long that work took. The formula to figure out the profitability of a project is below:

First it calculates the mag ratio:

mag ratio = project total magnitude / average total project RAC from last 30 days

Then you can get profitability (mag/hr):

profitability = (total credits earned / time those credits took) * mag ratio

Why is it setting all these projects weights to 1?

So that it can gradually accumulate enough stats to determine the profitability of these projects, and so those stats continue to update as projects change how their applications and credit assignment work. Note that 1 = .1% of your machine’s processing time since the total weight is 1000 not 100.

What if there’s a project I never want to crunch?

If you have a grudge against a particular project, you can add it to the ignore list at the top of the script.

What if there is more than one “most profitable” project?

If they are within 10% of each other, project weight will be split evenly between them. This insures crunching will continue even if one project runs out of work.

Why don’t you just say “crunch this project and if there’s no work available, crunch this other project?”

Because the BOINC client doesn’t have this ability, nor the ability to have projects be in groups. It’s open source though so feel free to contribute to the BOINC project or make your own BOINC Manager clone, this tool could certainly benefit from it!

What about CPUs or GPUs? Or different applications?

This tool doesn’t know about GPUs or different apps, it just calculates an average credits/hour over all work units sent to you by the project.

How often should I run this?

It’s up to you, but it uses a 30-day average to calculate RAC:MAG ratios, so running it very frequently won’t get you much benefit. It’s lightweight and doesn’t hammer the BOINC project servers though, so feel free to run it as often as you want!

What are you going to name the pony?

I don’t know, current candidates are Jeffrey and Stargazer.

What does “The following projects do not have enough stats to be calculated accurately” mean?

It means you have completed less than 10 tasks for this project. At ten tasks, under ideal circumstances, we could get within 10% of the correct “credits per hour” estimation which is needed to determine mag per hour. So if less than 10 WUs have been completed, we don’t even try to make an estimate.

Advanced Usage

What if I can’t run the Gridcoin wallet on my machine? For example, due to space limitations on my Raspberry Pi?

Then you can copy your BOINC data directory to a machine that has the wallet running and point the script to it. Note that you don’t need to copy any subfolders in the BOINC directory, just the root directory and files directly beneath it.
