I am comparing oranges to oranges. Work produced against work produced. How many average daily points produced with your Pi4? About 7000?

Now calculate have many you need to put out WUs like a high end AMD 3900X. Throughout this thread I have done that kind of calculation: about 20-25 Pi4s or 600000-750000 Rupees for about 260-325 watts.

I did some maths and presume currency is PKR.

Now we have apples to apples.

You have 2 gaming rigs so I presume you are comfortable with price. My rig is a bare bones tower with a big fan. Don't quite know how to cool laptops to that that level.

Obviously I were into the gaming thing I would not want to be using them for WCG at the same time.

hello,
new here.
Through my work i have come to hold 20 rpi4 2gb boards. I've always wanted to learn makig cluster or raids.
my knowledge is still limited and now I want to contribute to this community. my question is, can i contribute with a cluster of 20 rpi4 2gb? Assuming proper ethernet cables and power cables etc on my end, will the cluster be 'better' than adding one board to the community for helping?

People talk about points and rewards and stuff, i don't understand this, i just want to donate computing power that is otherwise sitting idle.

Just catching up on this VERY interesting thread! Thank you to those other contributors using Raspberry Pi's. I can speak to some of the issues with a collection of Pi's, and I have a question about work load after upgrading these to the recent Bullseye OS release.

First, I have 68 Raspberry Pi's. 20 are 3B+ and the rest are Pi 4's with different amounts of RAM. Almost all of these are used for WCG, and almost all of the work is for OPN1. I have a collection of scripts for managing groups of these, running apt (and apt-friends) to keep the OS up to date and for running other applications with a few Pi's in the cluster. My main interest is in running this miniature data center (the biggest problem is managing the heat!) , and WCG gives me something good to do in my retirement,

My question is have any similar Pi users have noticed a change in system load after upgrading your Raspberry Pi to the recent Bullseye OS release?

Prior to Bullseye (on PiOS Buster) all of these machines reported system loads (the last 3 numbers in response to the uptime command) around 4.0 - that is to be expected with 4 cores each devoting 100% of effort to one work unit. After Bullseye was installed these now report a system load between 6.5 and 8.0. I haven't yet compared the number of work units per day or checked the system temperatures, but I do know that the Pi's are slower to respond to remote ssh commands or remote requests to use boinccmd for status or updates.

Anybody else see anything like this and if so what if anything have you done about it?
