What are you trying to speed up?

Examples:

To provide more CPU for a multi-user interactive environment, look at  
distributed filesystems like NFS that'll allow users to log into  
either machine and get the same $HOME.

If you want to speed up C/C++ compiling, look at distcc.

For web applications, you can use various tricks to send different  
users to different machines.

If you've written a program and you want it to run faster, you likely  
need to add logic to take advantage of 2+ machines, and some libraries  
and kernel enhancements can make this easier (e.g. shared memory  
synchronized between machines using the network).

etc.
