-       These are converters from global to process pointers in memory
-       to global process pointers in message.
-       M denotes memory in which pair (pointer,object) exists or has to exist.
-       We want to create object denoting remote process instead of
-       dummy pointer without object.
-       The object will be like an arrayof integer of size 2.
-        arr[1..3] : arr[1]=node, arr[2]=pix.
