This program resolve a set of equations using the
Gauss method . At each step in the progress reduce the
matrix , the program also find the max value of any
valid rows in the same column .
The program can work well with the following pairs of
(amount of processes , amount of unknowns ) :
(3,10) ; (2,4) ;
