It's a little hard to tell what's going on without some additional 
information, such as the type of system on which you are running 
(processor, OS), the version of the Fortran compiler you are using (I'm
guessing Intel, if so you can use the "-V" option of the compiler to
retrieve compiler version). If running with PAPI, then version info there 
might also be useful.  Lastly, the output of the PerfSuite test suite can 
have some useful information (the result of "make check").

If using the Intel compiler, we have seen that for some versions (not 
all), standard profiling is broken and generates a run-time error.  
If that's the case with your version, then psrun using the "profil" style
of profiling will also fail.  You can check on this by compiling the example
program for profiling and seeing if it runs properly.  Check the "-help"
output of the compiler for the flags to use for compilation with gprof-style
profiling enabled.

Configuration options used when building PerfSuite are stored at the 
beginning of the file "config.log" after running the "configure" script, 
that can also help provide details for diagnosing.

If you can send that info along, we can see what might be happening.  You 
can send to per...@li... if you like, to minimize 
traffic here.

Thanks,
Rick
