Problem: This program defines the a parallel configuration similar to the one 
in the Connex Machine.
* It defines a chain, of N Processors (PEs)
* Each processor has two connections, left and right
* Processors start from 1 to N
* Assume CNX has 1024 processors (cells)

Example of Compilation:
	>p3 firstone.pm 
	OR
	>p3  firstone 
	OUTPUT: a.exe AND firstone.c
	Then 
	>a
	OR
	>p3c firstone
	OR
	>p3c firstone.pm
	OUTPUT: firstone.c
	Then
	Compile with a C compiler (preferably gcc)
Cycles:
