Using processors of many computers
 
Due to Corona matters , I can't go to the university to use the CFD Lab and now I am doing a simulation of a transient case which will take a lot of time if done using cores of one computer

so I have 2 computers and 1 laptop

Is there a way to connect them together to use all of their processors ?

If yes How I would do that in terms of Hardware connections and software connections?

thanks

AFAIK you can get benefits from many computers only if you use a high speed connection like InfiniBand. If you use regular Ethernet then connection between computers will become bottleneck and computational speed may even decrease compared to a single machine.

Second that. Without high-end connection between the units your additional resources will be eaten by the needed communication being to slow. Also I can imagine the cores with the least speed and RAM will just slow down all the others. I bet the overall performance will be worse compared to one computer.
