 In fact the scheduler's interface consist of a series of pointers to the specific-implementation functions. They are initialized by `initSched()` according to the configuration chosen in the [source:trunk/phase2/Makefile Makefile].
 Run-time switch between scheduling algorithms can be easily implemented with a function which performs a trivial update to interface pointers and internal data structure: the ready queue.

-=== modularizzazione in ph2 ===
-An important and unexpected benefit of modularization, convinces us of applying such principle in Phase 2 designing too. In fact, we escaped from the needing of generating exceptions after errors or, more generally, after abnormal situations. Consequently we opted for a direct '''function-call strategy''', which clearly minimizes the over-head caused by recursive raising of exceptions, in other words it reduces the number of context switches.
