fi_udp - The UDP Fabric Provider
The UDP provider is a basic provider that can be used on any system that supports UDP sockets. The provider is not intended to provide performance improvements over regular TCP sockets, but rather to allow application and provider developers to write, test, and debug their code. The UDP provider forms the foundation of a utility provider that enables the implementation of libfabric features over any hardware.
The UDP provider supports a minimal set of features useful for sending and receiving datagram messages over an unreliable endpoint.
The UDP provider has hard-coded maximums for supported queue sizes and data transfers. These values are reflected in the related fabric attribute structures
EPs must be bound to both RX and TX CQs.
No support for selective completions or multi-recv.
No support for counters.
No runtime parameters are currently defined.
