<p><b>New page</b></p><div>Is is possible to profile code compiled with the Intel Fortran compiler using gprof [http://www.cs.utah.edu/dept/old/texinfo/as/gprof_toc.html]. Intel Fortran's current release (9.1) requires Linux to generate profiling information.<br />
<br />
== Quick dive ==<br />
To generate profiling information follow these steps:<br />
# ifort -p foo.F90 -o foo<br />
# ./foo<br />
# gprof foo<br />
The first step will generate a executable with profiling information. At the end of the second step a file named gmon.out will be writen alongside the executable file; this file contains the profiling information generated during the program run. The third step screens the profile.<br />
<br />
Note: the -p option must be issued both to compile and link the program.<br />
<br />
== Profiling Mohid ==<br />
To profile Mohid open the Makefiles used on [[*NIX platforms]]. Find variable CC in every makefile and replace "ifort" with "ifort -p". make clean, make and execute Mohid. At the end of the run a file named gmon.out will be created in the executable's folder. Explore gmon.out issuing the command gprof Mohid.<br />
