Unfortunately, 'Will a beowulf speed things up for me?' isn't a simple
question and depends a lot on what you're doing.  Even with compiling,
there are some situations where it will help and others where it won't.

If your compiles are such that you have a lot of files that can be
compiled in parallel (as opposed to having to wait for others to be
compiled before they can be compiled) then its possible that a beowulf
cluster will help speed things up.  Also, if your compile is such that
your main slow down is the processor time to compile the files and not
the I/O time to read the files, then there's even more of a chance that
a beowulf cluster will help speed things up.

The tricky part is getting make (or something like it) to use a cluster
for compiling.  I have heard of companies that use clusters for
compiling like that, but unfortunately I know of no publiclly available
verion of make (or something similar) that can be setup to use a cluster
for compiling.   If anyone knows of one, I'd love to hear about it.
