    \caption{$\min t_{lat}$, $\tilde{t}_{lat}$, and $\max t_{lat}$  measured with \texttt{ib\_send\_lat}. All communication went over an \gls{rc} \gls{rdma} \gls{cm} \gls{qp} and was sent with the normal \textit{send} operation. Every test contained 1000 iterations and messages that were smaller than \SI{188}{\byte} were sent inline.}\label{tab:correlation_benchmarks}
