[Omp] Subroutines inside parallel block

[Patricia Bittencourt Sampaio]

  Hi Eric,

     Actually I wanted to know how the code is
executed . I had some troubles with the Omni Compiler
that I were using so I didn't have an opportunity to
check this. 
     I couldn't understand the main loop inside main
routine. This loop is parallelized with a parallel
directive. But no work sharing is used. And inside
this loop there is a call to rank routine. It means
that each tread calls rank MAX_ITERATIVES times,
correct?
     I wonder what happens inside rank(). There are
barrier and master directives, altough no parallel
region or a for directive is used to comprise barrier
and master directives. My question is what group of
treads execute the rank in parallel, if no parallel
region or for directive is defined.

thanks,

Patricia B. Sampaio
