Take a look at numpy.reshape .
>>> arr = numpy.zeros((50,100,25))

What does multicore assembly language look like?
... of the first instruction that the processor will execute as:
CS = XX * 0x100
IP = 0

So if for example XX == 1, the processor will start at 0x1000.
We must then ensure that ther...
