I have added support to gp for compiling multiple files simultaneously (akin to the -j4 flag to make). Since I have a dual processor machine, this dropped the total compile time for Interarchy from 8.4 minutes to 6 minutes.
I basically replaced ProcessDependencies and CompileIfNecessary, and hardly touched any of the rest of gp. But the sections replaced are essentially complete rewrites. It's not the most elegant of code, is still full of debugging code, is not written in gp-style, and does not currently support a command line switch, is minimally tested, and perhaps not all that efficient, but if anyone is interested, I'm happy to send them the code.
I think the effort to rewrite it into a clean patch for gp, would be worth the time spent on it. I believe it is useful on one-processor boxes also. In a decent OS that one processor can do something more useful than falling into sleep when threads get blocked by asynchronous IO requests, caused by file IO or virtual memory page faults.
Indeed. FWIW, it's an item on my list, and if Peter can't/doesn't want to rewrite his patch, I'll eventually add the functionality. But if you want to help adding it in GP "properly", Peter, feel free to contact me privately to discuss the details. (I'd obviously prefer to start from existing GP code and make as small changes as necessary.)
