Parallelism in the aC++ compiler

Parallelism in the aC++ compiler is available through the use of the following command-line options or libraries:

+O3 +Oparallel or +O4 +Oparallel optimization options—Automatic parallelization is available from the compiler; see the section “Levels of parallelism” for more information.
HP MPI—HP's implementation of the message-passing interface; see the HP MPI User's Guide for more information.
Pthreads (POSIX threads)— See the pthread(3t) man page or the manual Programming with Threads on HP-UX for more information.

None of the pragmas described in this book are currently available in the HP aC++ compiler. However, aC++ does support the memory classes briefly explained in Chapter 7 “Controlling optimization”, and more specifically in Chapter 11 “Memory classes”. These classes are implemented through the storage class specifiers node_private and thread_private.
