A masked dimension minimum value schedule is a communication schedule for finding, under the control of mask, the smallest elements of a distributed array along one of its dimensions, yielding a reduced array with rank one less than the source.
A masked dimension minimum value schedule is described by a collective object with local components of class MinvalDimMsk. The public interface of the MinvalDimMsk class is
class DAD ;
template<class T>
class MinvalDimMsk {
public :
MinvalDimMsk(const DAD* res, const DAD* src, const int dim,
const DAD* msk) ;
void execute(T* resDat, T* srcDat, int* mskDat) ;
private :
...
} ;
