The default the profile file is from the executable is run and the file is called gmon.out. Is there any way to specify a new location?

I encountered the same problem last week and I solved it in the following way. idea here is to change the process current directory to wherever you want to generate gmon.out file. file name can't be changed this way. It allows you to change where you can save the file.

#ifdef GPROF
                       /* so we can gprof */
                       if (1) {
                           char tmpdir[32];
                           snprintf(tmpdir, 32, "/tmp/%05d", mypid);
                           mkdir(tmpdir, S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH);
                           chdir(tmpdir);
                       }
#endif
