Dear professor:
I  partitioned my 2D cartesian  grid with  4rows*4cols CPUS.
                   12  13 14 15
                         8   9  10  11
                    4   5  6  7
                    0   1  2   3 
  
   Now i need to scatter the values  belonging to cpu5 to every cpu along  x direction( 4 5 6 7) , which  function should i use.

Regards
