+// We use a very simple "runtime" to parallelize our apps. We called it
+// bthread because it is a set of bare minimum "threading" library
+// functions to parallelize a program across multiple cores.
+//
+// All cores start from the main function. We need to call the
+// bthread_init() function at the beginning of main(). Basically only
+// core 0 can pass through the bthread_init function and continue
+// executing. The rest of cores (if any) will be trapped in the
+// bthread_init() function, waiting in a loop we call the worker loop. In
+// each iteration of the worker loop, a core will check if the flag is
+// set by core 0. If it is, then it will execute the function core 0
+// stored in a shared location, then reset its flag. Cores other than
+// core 0 will stay in the worker loop indefinitely.
+//
+// We call core 0 the master core, and we call the other cores the worker
+// cores. The master core "spawns work" on a worker core using the
+// bthread_spawn function. The master core needs the function pointer,
+// the argument pointer, and a worker core's ID. It stores the function
+// pointer and the argument pointer to a global location, then sets the
+// flag for the given worker core.
+//
+// The master core can wait for a worker core to finish by using the
+// bthread_join function. It waits for a designated worker core until the
+// worker core finishes executing its function (if any) then returns.
