I am new to Raspberry Pi's (as well as this stackexchange) and would like to use them to learn how to build a small cluster. (Currently using this guide: https://medium.com/@glmdev/building-a-raspberry-pi-cluster-784f0df9afbd)
I am a mathematics graduate student and so I am trying to gauge whether or not this project will actually be of use for some of my work. I would want to use a cluster for doing hundreds of millions of parallel linear algebra computations in R, Python and SageMath.
I would like to get an idea of the computational power of just one Raspberry Pi 4 Model B 2019 Quad Core 64 Bit WiFi Bluetooth (4GB). How would this compare to a cluster with something like Intel Core i3 processors, for example. Any advice and suggestions would be greatly appreciated! Thank you for your time!
