Nsupers Observer

Header file: <libs/observers/nsupers_observer.hpp> [source]

struct NsupersFunc

Functor operator to perform a copy of the number of superdroplets in each gridbox “nsupers” to d_data within Kokkos::parallel_for loop over gridboxes with range policy.

Signature of operator such that type can be used by GenericCollectData struct for FunctorFunc.

Note: Conversion of nsupers from size_t (architecture-dependent, usually long unsigned int = 8 bytes) to single precision (uint32_t = 4 bytes).

Param ii:

The index of the gridbox.

Param d_gbxs:

The view of gridboxes on device.

Param totsupers:

The view of superdroplets on device.

Param d_data:

The mirror view buffer for the number of superdroplets.

Public Functions

inline void operator()(const size_t ii, viewd_constgbx d_gbxs, const viewd_constsupers totsupers, Buffer<uint32_t>::mirrorviewd_buffer d_data) const
template<typename Store>
inline CollectDataForDataset<Store> auto CollectNsupers(const Dataset<Store> &dataset, const size_t maxchunk, const size_t ngbxs)

Constructs type sastifying the CollectDataForDataset concept for a given Store (using an instance of the GenericCollectData class) which writes the number of superdroplets in each gridbox “nsupers” during the functor call.

Parameters:

  • dataset – The dataset to write nsupers to.

  • maxchunk – The maximum chunk size (number of elements).

  • ngbxs – The number of gridboxes.

Returns:

CollectDataForDataset<Store> An instance satisfying the CollectDataForDataset concept for collecting the number of superdroplets in each gridbox.

template<typename Store>
inline Observer auto NsupersObserver(const unsigned int interval, const Dataset<Store> &dataset, const size_t maxchunk, const size_t ngbxs)

Constructs an observer which writes the number of superdroplets in each gridbox “nsupers” at start of each observation timestep to an array with a constant observation timestep “interval”.

Template Parameters:

Store – Type of store for dataset.

Parameters:

  • interval – Observation timestep.

  • dataset – Dataset to write time data to.

  • maxchunk – Maximum number of elements in a chunk (1-D vector size).

  • ngbxs – The number of gridboxes.

Returns:

Observer An observer instance for writing the number of superdroplets.
