\chapter{OpenFabrics Verbs\label{a:openfabrics}}
Experimental functions are not included in this appendix. Furthermore, the \gls{rdma} verbs \gls{api} is omitted because it is not used in the present work. A comprehensive documentation on all verbs can be found in the \gls{rdma} Aware Networks Programming User Manual~\cite{mellanox2015RDMA}.
