STATIC = omp_sched_static¶

DYNAMIC = omp_sched_dynamic¶

GUIDED = omp_sched_guided¶

void MEL::OMP::Functor::ARRAY_OP_FUNC(T *in, T *inout, int *len, MPI_Datatype *dptr)¶

Maps the given binary functor to the local array of a reduction / accumulate operation, using OpenMP for parallelism.

Parameters

• in -

  The left hand array for the reduction

• inout -

  The right hand array for the reduction. This array is modified to reflect the result of the functor on each element

• len -

  Pointer to a single int representing the number of elements to be processed

• dptr -

  Pointer to a single derived datatype representing the data to be processed

template <int NUM_THREADS, int CHUNK, Schedule SCHEDULE, typename T, T(*)(T &, T &) F>

MEL::Op MEL::OMP::OpCreate(bool commute = true)¶

Maps the given binary functor to the local array of a reduction / accumulate operation, using OpenMP for parallelism.

See

MPI_Op_create

Return

Returns a handle to a new Op

Parameters

• commute -

  Is the operation commutative
