Cluster computing

Hello: I have two older generation of computers that I would like to setup as a two node cluster for Blender animation rendering/video editing. One computer has a graphic card and the other computer has no graphic card. I will be using high speed Ethernet adapter to connect both computer to...

I am interested in setting up a Raspberry Pi 3 cluster. But how much processing power would I obtain if I were to set up a 16 PI cluster? Would it be more powerful than an i5 at least?

If I took a Raspberry Pi CM3 clusterboard (e.g.: https://www.cnx-software.com/2017/08/16/pine64-sopine-cluster-board-takes-up-to-seven-sopine-a64-systems-on-module/) and installed some SODIMM RAM into the slots, would they work?

Can you use a male to male DIMM riser as a high speed interconnect between computers in a cluster? You could get the lower latency than PCIe and a decent amount of bandwidth (according to kanewolf, latency is WAY more important than bandwidth). So would that work?

For this to make sense, look at the EPYC's infinity fabric. You see how all the dies are connected to one another, why can't this work for compute clusters? Instead of having 1 master processor and multiple slave processors, why don't we have them equally connected so any processor can talk to...

If you are connecting computers over PCIe to become a compute cluster, how many PCIe lanes are enough? Is it x4? x16? Or do you need more (like 2 x16 slots)? Or does it not matter?

I have a 1500$ (AUD). First time going to buy/build this PC. I be using it for gaming/ editing/ streaming and school work. https://au.pcpartpicker.com/list/DMP9XP RATE MY PC AND TIPS THANKYOU
