execute()

virtual StatusCode CaloClusterGPUProcessor::execute ( const EventContext &  ctx, const CaloRecGPU::ConstantDataHolder &  constant_data, CaloRecGPU::EventDataHolder &  event_data, void *  temporary_buffer  ) const

pure virtual

Process the clusters on GPU.

Parameters

ctx	The event context.
constant_data	Data held in GPU memory that is common to all events (cell noise and geometry).
event_data	Data held in GPU memory that is specific to this event (including the description of the clusters themselves).
temporary_buffer	A pointer to an \array in GPU memory that is at least as large as size_of_temporaries(), to hold temporary information for the algorithms. Given the way CUDA memory allocations work, casting this to a pointer (or a CaloRecGPU::Helpers::CUDA_kernel_object) to the intended type and then using it will be perfectly valid.

Implemented in TopoAutomatonClustering, BasicGPUClusterInfoCalculator, GPUClusterInfoAndMomentsCalculator, TopoAutomatonSplitting, CaloGPUOutput, and CaloCellsCounterGPU.

size_of_temporaries()

virtual size_t CaloClusterGPUProcessor::size_of_temporaries ( ) const

inlinevirtual

The size (in bytes) of the temporary object(s) that the algorithm will use.

Reimplemented in BasicGPUClusterInfoCalculator.
