        \toprule
        \textbf{Notation} & \textbf{Meaning} & \textbf{(See also)} \\
        \midrule
        $\cyc{\kerK}$
            & Reciprocal throughput of $\kerK$, in cycles per occurrence of
              $\kerK$.
            & §\ref{def:cyc_kerK} \\
        $\cycmes{\kerK}{n}$
            & Measured reciprocal throughput of $\kerK$, over $n$ iterations of
            $\kerK$. When there is no ambiguity and $n$ is sufficiently large,
            we often write $\cyc{\kerK}$ instead.
            & §\ref{def:cycmes_kerK} \\
        $\cycB{\kerK}$
            & Reciprocal throughput of $\kerK$ if it was only limited by the
            CPU's backend.
            & §\ref{def:cycB} \\
        $\cycF{\kerK}$
            & Reciprocal throughput of $\kerK$ if it was only limited by the
            CPU's frontend.
            & §\ref{def:cycF} \\
        $C(\kerK)$
            & Number of cycles of a kernel $\kerK$.
            & §\ref{def:ker_cycles} \\
        $\kerK^n$
            & $\kerK$ repeated $n$ times.
            & §\ref{not:kerK_N} \\
        $\operatorname{IPC}(\kerK)$
            & Instructions Per Cycle in the execution of the kernel $\kerK$, in
            steady state, averaged.
            & §\ref{def:ipc} \\
        $\mucount{}i$
            & Number of \uops{} the instruction $i$ is decoded into. This can
            be extended to a kernel: $\mucount{}\kerK$.
            & §\ref{def:mucount} \\
        $\tau_K$
            & Kendall's $\tau$ coefficient of correlation.
            & §\ref{ssec:palmed_eval_metrics}, \cite{kendalltau} \\
