QUESTION: Can I use HP-MPI in my C++ application?
ANSWER: Yes, HP-MPI currently provides C++ classes for the MPI
bindings.The classes provided are an inlined interface class to the MPI C
bindings. Although most of the classes are inlined, a small portion is a
pre-built library. This library is g++ ABI compatible. Because some C++
compilers are not g++ ABI compatible, we provide the source files and
instructions on how to build this library with your C++ compiler if
necessary. For more information, see “C++ bindings (for HP-UX and
Linux)” on page 50.
QUESTION: How can I tell what version of HP-MPI I’m using?
ANSWER: Try one of the following:
• % mpirun -version
• (on HP-UX) % swlist -l product|grep "HPMPI"
• (on Linux) % rpm -qa|grep "hpmpi"
For Windows, see the Windows FAQ section.

ANSWER: RedHat Enterprise Linux AS 2.1, 3.0, 4.0, and SuSE SLES 9,
and 9.1, 9.2, 9.3, and 10.0 are officially supported. Other versions may
