\chapter{The \code{omp\_get\_num\_threads} Routine}
|
|
\label{chap:get_nthrs}
|
|
|
|
In the following example, the \code{omp\_get\_num\_threads} call returns 1 in
|
|
the sequential part of the code, so \code{np} will always be equal to 1. To determine
|
|
the number of threads that will be deployed for the \code{parallel} region, the
|
|
call should be inside the \code{parallel} region.

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