How to create a table with multiple columns?

Question

I'm new to the latex world. Is there a way to produce a table like the following?

I've tried with the following code exploiting multirow, siunitx and booktabs packages following this reference https://tex.stackexchange.com/a/174328/233121 but the result is not really the expected one.

\documentclass[11pt]{article}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{multirow}
\begin{document}
\begin{table}[ht]
\begin{tabular}{
  l
  *{6}{S[table-format=1.4]}
  S[table-format=5]
  S[table-format=3.2]
}
\toprule
\multicolumn{1}{c|}{\textbf{Program}} &
\multicolumn{1}{c|}{\textbf{Problem Size}} &
\multicolumn{4}{c|}{\textbf{Instructions (Billions)}}  &
\multicolumn{3}{c}{\textbf{Synchronization Primitives}} \
\cmidrule(lr){3-6} \cmidrule(lr){7-9}
&& {\textbf{Total}} & {\textbf{FLOPS}} & {\textbf{Reads}} & {\textbf{Writes}} & {\textbf{Locks}} & {\textbf{Barriers}} & {\textbf{Conditions}} \
\midrule
\texttt{blackscholes}  & 65,536 options & 2.67 & 1.14 & 0.68 & 0.19 & 0 & 8 & 0 \
\texttt{freqmine} & 990,000 transactions & 33.45 & 0.00 & 11.31 & 5.24 & 990,025 & 0 & 0 \
\texttt{swaptions}  & 64 swaptions, 20,000 simulations & 14.11 & 2.62 & 5.08 & 1.16 & 23 & 0 & 0 \
\texttt{bodytrack} & 4 frames, 4,000 particles & 14.03 & 4.22 & 3.63 & 0.95 & 114,621 & 619 & 2,042 \
\bottomrule
\end{tabular}
\end{table}
\end{document}

I'd like to find a solution in order to automatically wrap overfulling text but can't figure it out.

Here is a way to do that table (in landscape mode because, otherwise, it's too wide).

\documentclass[landscape]{article}
\usepackage{geometry}
\usepackage{nicematrix}
\usepackage{siunitx}
\begin{document}
\begin{table}[ht]
\setlength{\tabcolsep}{5pt}
\begin{NiceTabular}{ll*{5}{S}S[table-format=4.0]S}[hvlines]
\Block{2-1}{\textbf{Program}} &
\Block{2-1}{\textbf{Problem Size}} &
{\Block{1-4}{\textbf{Instructions (Billions)}}}  &&&&
{\Block{1-3}{\textbf{Synchronization Primitives}}} \
&& {\textbf{Total}} & {\textbf{FLOPS}} & {\textbf{Reads}} & {\textbf{Writes}} & {\textbf{Locks}} & {\textbf{Barriers}} & {\textbf{Conditions}} \
\texttt{blackscholes}  & 65,536 options & 2.67 & 1.14 & 0.68 & 0.19 & 0 & 8 & 0 \
\texttt{freqmine} & 990,000 transactions & 33.45 & 0.00 & 11.31 & 5.24 & 990,025 & 0 & 0 \
\texttt{swaptions}  & 64 swaptions, 20,000 simulations & 14.11 & 2.62 & 5.08 & 1.16 & 23 & 0 & 0 \
\texttt{bodytrack} & 4 frames, 4,000 particles & 14.03 & 4.22 & 3.63 & 0.95 & 114,621 & 619 & 2,042 \
\end{NiceTabular}
\end{table}
\end{document}

You need several compilations.

The output is certainly better with only the horizontal rules provided by bookmarks:

\documentclass[landscape]{article}
\usepackage{geometry}
\usepackage{nicematrix}
\usepackage{siunitx}
\usepackage{booktabs}
\begin{document}
\begin{table}[ht]
\setlength{\tabcolsep}{5pt}
\begin{NiceTabular}{@{}ll*{5}{S}S[table-format=4.0]S@{}}
\toprule
\Block{2-1}{\textbf{Program}} &
\Block{2-1}{\textbf{Problem Size}} &
{\Block{1-4}{\textbf{Instructions (Billions)}}}  &&&&
{\Block{1-3}{\textbf{Synchronization Primitives}}} \
\cmidrule(lr){3-6} \cmidrule(l){7-9}
&& {\textbf{Total}} & {\textbf{FLOPS}} & {\textbf{Reads}} & {\textbf{Writes}} & {\textbf{Locks}} &
{\textbf{Barriers}} & {\textbf{Conditions}} \
\midrule
\texttt{blackscholes}  & 65,536 options & 2.67 & 1.14 & 0.68 & 0.19 & 0 & 8 & 0 \
\texttt{freqmine} & 990,000 transactions & 33.45 & 0.00 & 11.31 & 5.24 & 990,025 & 0 & 0 \
\texttt{swaptions}  & 64 swaptions, 20,000 simulations & 14.11 & 2.62 & 5.08 & 1.16 & 23 & 0 & 0 \
\texttt{bodytrack} & 4 frames, 4,000 particles & 14.03 & 4.22 & 3.63 & 0.95 & 114,621 & 619 & 2,042 \
\bottomrule
\end{NiceTabular}
\end{table}
\end{document}

I like both your solutions! Unfortunately I'm currently working on my thesis and I'm obliged to work with this format \documentclass[10pt,twoside,openright,english,italian]{book}. Do you think there is a workaround to fit the table? — browser-bug, Mar 22 '21 at 15:39
I would rotate th tabular by 90° (\rotatebox{90}{...}) and let LaTeX puts the table as it usually does for all the floats. — F. Pantigny, Mar 22 '21 at 16:01

Your table is to wide that can be fit in on page's text area
as possible solutions enabling split text in the second column into multi lines
also will help use smaller font and reduce size of the \tabcolsep:

\documentclass[10pt,twoside,openright,english,italian]{book}
\usepackage{geometry}  % added
\usepackage{siunitx}
\usepackage{booktabs, multirow, 
            tabularx} % added 
\newcolumntype{L}{>{\raggedright\arraybackslash}X}
\NewExpandableDocumentCommand\mcc{O{1}m}{\multicolumn{#1}{c}{#2}}
\begin{document}
    \begin{table}[ht]
    \centering
    \setlength\tabcolsep{3pt}
    \small
\begin{tabularx}{\linewidth}{@{} 
  l L
    S[table-format=2.2]
    S[table-format=1.2]
    S[table-format=2.2]
    S[table-format=1.2]
%
    S[table-format=3.3]
    S[table-format=3.0]
    S[table-format=1.3]
                @{}}
    \toprule
\textbf{Program}

    & \textbf{Problem Size}
        & \mcc[4]{\textbf{Instructions (Billions)}}

            & \mcc[3]{\textbf{Synchronization Primitives}} \
    \cmidrule(lr){3-6} \cmidrule(lr){7-9}
    &   & {\textbf{Total}} 
            & {\textbf{FLOPS}} 
                & {\textbf{Reads}}

                            & {\textbf{Barriers}} 
                                & {\textbf{Conditions}} \
\midrule
\texttt{blackscholes}  & 65,536 options & 2.67 & 1.14 & 0.68 & 0.19 & 0 & 8 & 0 \

\texttt{swaptions}  & 64 swaptions, 20,000 simulations & 14.11 & 2.62 & 5.08 & 1.16 & 23 & 0 & 0 \
\texttt{bodytrack} & 4 frames, 4,000 particles & 14.03 & 4.22 & 3.63 & 0.95 & 114,621 & 619 & 2,042 \
\bottomrule
\end{tabularx}
    \end{table}
\end{document}

addendum: small variation where for X column is used \renewcommand\tabularxcolumn[1]{m{#1}} and enlarge table stretch:

\begin{document}
    \begin{table}[ht]

    \setlength\tabcolsep{3pt}
    \renewcommand\arraystretch{1.2}

            & \mcc[3]{\textbf{Synchronization Primitives}} \
    \cmidrule(lr){3-6} \cmidrule(lr){7-9}
