10. Networking system support
Open MPI supports a variety of different networking transports for off-node communication. Not all of these transports are supported or available on every platform. Many require specialized hardware, operating system drivers, and/or network transport libraries.
When Open MPI is being configured, it will search for a variety of
network transport libraries (and corresponding development header
files). By default, if
configure can find a network transport
library and its development header files, it will include support for
that library. If
configure does not find a library or its header
files, it will simply skip that library (and Open MPI will simply not
build support for that library).
The sections listed below are by no means comprehensive.
