Hi again,
Thanks for fixing the problem so fast. I could make pfmon work without
problem. However, coming back to the issue why I wrote first, I cannot
monitor properly just a function in my code. I repeated the
one-thread-test with the new pfmon version and I got 0's again:
./pfmon -uk --verb --follow-pthread --trigger-code-start=producto
--trigger-code-stop=producto --trigger-code-follow

Maybe I misunderstood the symbols the compiler (icc) created. If I run
the code with 2 threads inspecting the object "L_producto_21__par_loop1"
I get also 0's in the 3 threads. However, if I inspect the object
"L_main_21__par_loop0" I get data in 2 of the 3 threads:

So, taking into account that I only requested 2 threads, maybe the
outcomes are correct, and I'm getting the information about the 2
threads in a different symbol (L_main_21__par_loop0) because the
compiler placed the parallel,openMP code there, instead of inside the
"producto" function. What I don't understand is why pfmon doesn't follow
to "L_main_21__par_loop0" from "producto".

Juan Ángel
