Detailed Description

template<typename T>
class Reducer< T, ReducerType::Max >

Reducer for finding the maximum of many values.

Provides cheap operator (<<) for "inserting" potential max values.

Example:

• ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reducer<double,ReducerType::Max> max_val;

  // ... (somewhere in main task) max_val = 0.0; forall(A, N, [](double& A_i){ max_val << A_i; }); LOG(INFO) << "maximum value: " << max_val;
