If you have the Support Tools Manager installed
which is part of the Online Diagnostics Bundle from the
half yearly issued Support PLUS Patch Bundles by HP
and doesn't require an extra license
(it is highly recommended to have it installed for various other diagnostics)
then you could query the memory map like
Code:
$ echo "sc prod memory;info;wait;il"|/usr/sbin/cstm |grep -i total.*memory
    Total Configured Memory   : 8192 MB

This is the release I use on this box for instance
Code:
$ /usr/sbin/swlist -l bundle OnlineDiag|grep ^[^#]
  OnlineDiag    B.11.11.20.02  HPUX 11.11 Support Tools Bundle, December 2007

TAU_TRACK_MEMORY_HEA(3) 				      TAU Instrumentation API					   TAU_TRACK_MEMORY_HEA(3)

NAME
TAU_TRACK_MEMORY_HEADROOM - Track the headroom (amount of memory for a process to grow) by periodically interrupting the program SYNOPSIS
C/C++: TAU_TRACK_MEMORY_HEADROOM(void); Fortran: TAU_TRACK_MEMORY_HEADROOM(void); DESCRIPTION
Tracks the amount of memory available for the process before it runs out of free memory on the heap. This call sets up a signal handler that is invoked every 10 seconds by an interrupt (this interval may be altered by using the TAU_SET_INTERRUPT_INTERVAL call). Inside the interrupt handler, TAU evaluates how much memory it can allocate and associates it with the callstack using the TAU context events (See TAU_REGISTER_CONTEXT_EVENT(3)). The user can vary the size of the callstack by setting the environment variable TAU_CALLPATH_DEPTH (default is 2). This call is useful on machines like IBM BG/L where no virtual memory (or paging using the swap space) is present. The amount of heap memory available to the program is limited by the amount of available physical memory. TAU executes a series of malloc calls with a granularity of 1MB and determines the amount of memory available for the program to grow. EXAMPLE
C/C++ : TAU_TRACK_MEMORY_HEADROOM(); Fortran : call TAU_TRACK_MEMORY_HEADROOM() SEE ALSO
TAU_TRACK_MEMORY(3), TAU_SET_INTERRUPT_INTERVAL(3), TAU_ENABLE_TRACKING_MEMORY_HEADROOM(3), TAU_DISABLE_TRACKING_MEMORY_HEADROOM(3), TAU_TRACK_MEMORY_HEADROOM_HERE(3) 08/31/2005 TAU_TRACK_MEMORY_HEA(3)
