# NAME
fi_guide \- libfabric programmer's guide
# OVERVIEW
libfabric is a communication library framework designed to meet the
performance and scalability requirements of high-performance computing (HPC)
applications. libfabric defines communication interfaces that enable a
tight semantic map between applications and underlying network services.
Specifically, libfabric software interfaces have been co-designed with
network hardware providers and application developers, with a focus on
the needs of HPC users.
This guide describes the libfabric architecture and interfaces. Due to
the length of the guide, it has been broken into multiple pages. These
sections are:
*Introduction [`fi_intro`(7)](fi_intro.7.html)*
: This section provides insight into the motivation for the libfabric
design and underlying networking features that are being exposed through
the API.
*Architecture [`fi_arch`(7)](fi_arch.7.html)*
: This describes the exposed architecture of libfabric, including the
object-model and their related operations
*Setup [`fi_setup`(7)](fi_setup.7.html)*
: This provides basic bootstrapping and setup for using the libfabric API.
