Calculated as dim * dim * dim * 3 * sizeof (int) ,
where dim - dimension of matrixes.
Memory allocated by the operation system for arrays m1, m2, m3.
Address space, rezerved by the operation system for arrays m1, m2, m3.
Not all reserved memory pages are physically allocated.
Contains time, recounted for one pass of the innermost cycle.
Calculated as T / (dim * dim * dim) ,
where T - total time, dim - dimension of matrixes.
Normalized time may be considered as time for accumulation
sum += m1 [i] [k] * m2 [k] [j];
