General table notes:
The default notes for a table are based on the default definition of
the table, and do not account for the effects of command-line options
that may modify the content of the table.
Detailed notes, produced by the pat_report -v option, do account for
all command-line options, and also show how data is aggregated, and
if the table content is limited by thresholds, rank selections, etc.
An imbalance metric in a line is based on values in main threads
across multiple ranks, or on values across all threads, as applicable.
An imbalance percent in a line is relative to the maximum value
for that line across ranks or threads, as applicable.
If the number of Calls for a function is shown as "--", then that
function was not traced and the other values in its line summarize
the data collected for functions that it calls and that were traced.
Experiment: trace
