The "make -j" option is a very powerful tool not only in terms of compilation. We have been using this also for rendering and other time consuming jobs. It basically allows you to build in parallel any target described in a Makefile. Implementation of MPI based plugin module for GNU Make (the -j option comes with a well defined interface to spawn the "threads" and it is easy to implement that for any MPI or even socket interconnected number of hosts) in combination with shared file system has allowed us to build various time consuming projects on computer clusters gaining almost linear scaling.
