IIUC, the diff b/t go and most languages is that go spawns threads through a slicing mechanism to leverage multiple cores, right?! That's why the go version speeds up when run on multiple-core systems...right?
Included in the paste are the execution times on my lowly dual-core laptop. Spawning more threads speeds up the program. I would be curious to see how it scales to more cores on modern CPUs. If you have a chance, won't you please give it a try on your system and let me know how changing the number of threads affects execution time?
So, I added pthreads to the ray-tracer program: http://pastebin.com/6V5JYyZG

For anyone who wants to try pthreads in C, the simplest example and progressions I could find were here: http://cs.gmu.edu/~white/CS571/Examples/pthread_examples.htm...
