# Scalability sweep for the distributed deadlock test (loopback).
|
|
# For each size, starts a fresh server hosting a ring of `nodes` plus `res1`+`res2` densely
|
|
# cross-referencing resources, then runs the client (WaitWithCycleDetection) and records the
|
|
# graph size, back-edges, cycle-breaks, and completion time. Output: sweep-results.csv / .md
