描述

New feature

The nextflow execution report is a very helpful tool for profiling pipeline performance and resource allocation. The current report describes well the per-process distribution of runtimes, but does not report the cumulative realtime duration by process.

Use case

I have some process which run in reasonable amount of time, but are executed many thousands of times, leading to very large cumulative runtimes. These processes are great candidates for performance optimization, but do not stand out in the current report.

Suggested implementation

I currently derive this from the trace file, but it would be right at home as a cumulative runtime bar plot in a separate tab of the Job Duration section of the execution report.

研究方向
Start by examining the existing execution report generation code, likely in the modules that produce HTML/plots. Look for the Job Duration section and how the current distribution plot is built. The cumulative duration bar plot could be added as a new tab following the same pattern. Consider leveraging the trace file parsing already present. Since no comments or PRs exist, the contributor should propose a design in the issue before coding.
