\paragraph{Context}
20+
As stated in \Cref{sec:purpose}, Deliverable~D7.1 inaugurates the annual benchmarking series for Exa-MA and documents the shared methodology underpinning the WP1--WP6 advances.
21+
This appendix consolidates the maintenance view for release~v2.0.0 so that successive editions can track progress consistently.

\paragraph{Version trail}
24+
The change log on the identification page records the key milestones: the v1.90.0 rebuild of the table of contents, the October 2025 WP contributions (v1.91.1 and v1.91.2), the KPI table refresh (v1.92.0), the publication statistics update (v1.93.0), and the major v2.0.0 release introducing document tooling infrastructure.
25+
Release v2.0.0 marks a significant milestone with enhanced automation capabilities.
26+
Each iteration aligns with the benchmarking methodology in Chapter~\ref{chap:methodology} and feeds the KPI snapshot presented in Section~\ref{sec:summary}.
27+
28+
\paragraph{Forward-looking scope}
29+
Future releases will incorporate the benchmarking extensions and automation priorities already outlined in the Future Work section of Section~\ref{sec:conclusions}, ensuring that KPIs, datasets, and CI artefacts stay synchronized with NumPEx requirements.
30+
The v2.0.0 tooling enhancements establish a foundation for automated document analysis, dependency tracking across all 31+ included files, and streamlined document expansion workflows that support reproducible builds and systematic quality assurance.

Several challenges were encountered during the benchmarking process:

\begin{itemize}

\item \textbf{Memory Usage:}
297-
\item \textbf{Parallelization Inefficiencies:}
298-
\item \textbf{Cache and Memory Bottlenecks:}
296+
\item \textbf{Memory usage:} the largest mesh (\texttt{Mr6}) cannot complete on a single 128-core node because of memory limitations, requiring multi-node execution to progress.
297+
\item \textbf{Parallelization inefficiencies:} despite the decrease in absolute runtimes, the nonlinear solve and assembly phases remain the dominant contributors, signalling limited scaling benefits for those kernels when adding nodes.
298+
\item \textbf{Cache and I/O bottlenecks:} as the number of cores increases, the proportion of time spent exporting results grows due to the larger data volumes written to disk, stressing memory bandwidth and storage throughput.
