Understanding caliper scgprof report, term 'cycles'

[Raghava_1]

Hi,

We attached caliper to an exe in our environment and obtained the call graph profiles. (caliper scgprof)

The report has the below contents to say

[Minimum function entries: 5, percent cutoff: 1.00, cumulative percent cutoff: 100.00]


Further, in call graph listing, we see entries like "". What do these entries convey? What does the report mean when it says 'cycle # as a whole' without reference to any particular function (as seen in hot call path data given above).

Please help me understand the content of the report.

Cycles typically means recursions.

>"". What do these entries convey?

It probably means all of the recursive functions, taken as a whole, account for that percentage.
