proc n
process body

where n is a variable or value known at compile time.


This will limit execution of a block to a certain process whose rank is guaranteed to be that specified.

Note: A variable declared within a proc block and allocated multiple will in fact, by inference, be allocated to the group of processes which contains a single process who's rank is the same as the proc block's.


#include <io>
function void main() {
   proc 0 {
      print("Hello from 0\n");

   proc 1 {
      print("hello from 1\n");

The code example will run on two processes, the first will display the message Hello from 0, whilst the second will output the message hello from 1.
