Parallel Programming Guide for HP-UX Systems

Memory classes
Chapter 7124
• Private versus shared memory
• Memory class assignments
The information in this chapter is provided for programmers who want to
manually optimize their shared-memory programs on a single-node
server. This is ultimately achieved by using compiler directives or
pragmas to partition memory and otherwise control compiler
optimizations. It can also be achieved using storage class specifiers in C
and C++.
