- In Top-Down Callstack or Flame Graph, if the
ROOT node branches out to more than two nodes then increase callstack unwind
depth with
--call-graph-depth. Maximum depth supported is 1024. - If worker threads parallel region callstack is not stitched with master thread,
and if application is creating more than 1000000 parallel regions, increase this
limit by setting the environment variable
AMDUPROF_MAX_PR_INSTANCES.$export AMDUPROF_MAX_PR_INSTANCES=2000000
