Did you know?
WebbGprof is a performance analysis tool used to profile applications to determine where time is spent during program execution. Gprof is included with most Unix/Linux implementations, is simple to use, and can quickly show which parts of an application take the most time (hotspots). Webb28 okt. 2024 · Gprof: The first step in generating profile information for our program is to compile and link it with profiling enabled. i.e -pg (profile generation) gcc simple.c -o simple -pg Once the program is compiled for profiling, we must run it in order to generate the information that gprof needs. ./simple

This information can show you which pieces of your program are slower than you expected, and might be candidates for rewriting to make your program execute faster.
WebbMy understanding is that in order to use gprof, I have to generate a gmon.out file, and that in turn this is generated by compiling and running my program with the "-pg" option.
