Check out the file $WM_DIR/wmake for the details.
The funny thing is: that variable is not initialized under OpenFOAM 1.4.
Just add the following line to your $WM_PROJECT_DIR/$FOAM_DOT_DIR/bashrc
Adjust the number to the number of processors you want to use for compiling.
(For csh, adjust your file $WM_PROJECT_DIR/$FOAM_DOT_DIR/cshrc
setenv WM_NCOMPPROCS 2
Thanks Martin... that worked p
Thanks Martin... that worked perfectly. I've been trying out some different optimizations with the pre-release GCC 4.2 and it really helps cutting the compile time down.

You can also distribute parallel builds. Works great on clusters. See the Wiki page about wmake.
