Weak-scaling tests with [2*tests/50_DP_Al per node] was performed on Sugon DCU platform, and the results are illustrated below. Weak-scaling efficiency is lower than 30% when the number of nodes is larger than 32. The time tables seem strange as large parts of time are missing.

- Reproduce the performance issue on a similar system or environment.
- Identify the specific section of the code causing the performance issue.
- Investigate the issue and determine the root cause.
- Research best practices and potential solutions for the identified performance issue.
- Implement the chosen solution to address the performance issue.
- Test the implemented solution to ensure it improves performance without introducing new issues.
- Optimize the solution if necessary, considering trade-offs between performance and other factors (e.g., code complexity, readability, maintainability).
- Review and incorporate any relevant feedback from users or developers.
- Merge the improved solution into the main codebase and notify the issue reporter.
