call to split the "diago world" the unit of first proc of each grid group us the diag world. for example, if we have 64 processors, and diago_proc = 4, then we have 4 'grid world', which have 16, 16, 16, 16 processors each, and the head of each 'grid world' leads to the 'diag world', diag is only carried out using those 4 proc.
