How to combine multiple raspberry pi?

Question

Raspberry Pi

How to combine Raspberry pi into a cluster (let's say 5 pcs) and use their processor cores as one. Valid for password hash brute force or other tasks

Answer 1

It is impossible to combine several computers into one. For distributed computing, special software is used that can work on a cluster.

Answer 2

No one desktop will tear a dozen raspberries, and if there are a couple of vidyuhas, then a hundred.

Answer 3

There is a concept of cluster HAT . Looks nice - how it works - did not understand.

Answer 4

As rightly noted here, the question is not quite correct. It is impossible to combine several computers into one (use the cores as one), but this is not required. If the task can be parallelized, that is, some pieces of code can be executed independently of the execution of other code, then such pieces can be transferred to other computers for a solution.
For example, password hash calculation is really easy to parallelize. Instead of one computer doing the calculations, it broadcasts these resource-intensive requests to other computers (usually a bunch).
You can start, for example, by reading the SOA architecture (service oriented architecture) device, this will take some time.
