Connecting two motherboards on the same system.....

Hi guys,
I am new to this forum.
Can u guys please help me combining two motherboards on the same system. Something like a custom server.

Thanks

"like a server"? whats the purpose of this?

motherboards can't be "combined", you can put multiple motherboards in one case, but this just gives you two computer in the space of one, they would still be completely separate

you can also put multiple computers together (usually with a high speed network) and have them work together on one job, this would be basically a software situation where you still have multiple computers, but your software can either show an application the resources of all combined computers, or the application itself can talk to other computers to share its load (distcc does this), using multiple computers connected in this manner is usually only used when there are other limiting factors or the hardware already exists (its useful for compiling an application using all the computers in your house, or running software on 10,00 CPUs), the drawbacks are mainly high latency as the CPU-CPU communication is severely limited by the network so its only useful if you have a highly threaded application that can share very little between threads

the most common method for more speed is to just get a motherboard that supports multiple CPUs, these motherboards can usually support 2 or 4 processors (up to 4 cores each), some exist that suport more (8-socket), and if you want more you will probably need a specially built server (mainframe type system)
