- profile(:Goal)
- profile(:Goal, +Options)
- Run
once(Goal) under the execution profiler. If the (xpce) GUI is
enabled this predicate is hooked by library(swi/pce_profile) and
results are presented in a gui that enables navigating the call tree
and jump to predicate implementations. Without the GUI, a simple
textual report is generated. Defined options are:
- time(Which)
- Profile
cpu or wall time. The default is CPU time.
- sample_rate(Rate)
- Samples per second, any numeric value between 1 and 1000.
Default is defined by the Prolog flag
profile_sample_rate,
which defaults to 200.
- ports(Bool)
- Specifies ports counted -
true (all ports), false (call
port only) or classic (all with some errors).
Accomodates space/accuracy tradeoff building call tree.
Default is defined by the Prolog flag profile_ports,
which defaults to true.
- top(N)
- When generating a textual report, show the top N predicates.
- cumulative(Bool)
- If
true (default false), show cumulative output in
a textual report.
- See also
- - show_coverage/2 from library(test_cover).
- To be done
- - The textual input reflects only part of the information.
