Mesh topology minimum required number of computers?

Answer 1

The minimum needed to make the mesh. "Mesh" could refer to several types of groups of computers. There is grid computing, where a large number of small computers all work in parallel. Modern supercomputers, like those used by physicists and weather forecasters (seriously), use grids. Another is distributed computing. Nearly identical in description, the difference is in parlance. Grid may refer to large numbers of computers at one company under control of a dedicated group, where distributed computers usually means dispersed computers. An example might be many computer systems at top research universities working on the same problem. Another is cloud computing. Clouds are groups of computers not necessarily working together on something. The internet is one example. Seti@Home is famous for harnessing the individual power of millions of (simple, low-power) computers throughout the Internet cloud to create an ultrapowerful distributed grid. You no longer need to create your own supergrid software. You can hire a company like grid.org to solve your problem. For example, analyzing chemicals to see if they'd have any effect on cancerous cells.

Answer 2

To create any network you need at least 2 computers, the MASH network is not an exception. But if you want use benefits of mesh topology you need to have at least 3 computers.
