   Hi,

       Program:
       --------
       I have a program that builds a huge graph. During the 
       graph building phase a lot heap space (malloc()) is
       used and a lot of stack space is used during the graph
       traversal as it is extremely recursive.

       Environment:
       --------
       The above mentioned program is tested on an IBM RS6000 
       (model 530 AIX 3.1) with ~ 80 MB of real memory and 256 MB 
       of paging space.
       
       Problem:
       --------
       The program is abnormally terminated during the graph traversal
       phase for lack of paging space. Increasing the paging space beyond
       256 MB doesn't seem to help. 

       Question:
       ---------
       Is it possible possible for the above mentioned program to work
       if I thrown in extra memory boards? Do extra memory boards
       increase the data (heap+stack) space? Please shed some
       light on this issue. Thanks for your time.
