In the following example, the \kcode{omp_get_num_threads} call returns 1 in 
the sequential part of the code, so \ucode{np} will always be equal to 1. To determine 
the number of threads that will be deployed for the \kcode{parallel} region, the 
call should be inside the \kcode{parallel} region.

The following example shows how to rewrite this program without including a query 
for the number of threads:
