compute()

void RooBatchCompute::CUDA::RooBatchComputeClass::compute ( RooBatchCompute::Config const & cfg, Computer computer, std::span< double > output, VarSpan vars, ArgSpan extraArgs )

inlineoverridevirtual

Compute multiple values using cuda kernels.

This method creates a Batches object and passes it to the correct compute function. The compute function is launched as a cuda kernel.

Parameters

computer	An enum specifying the compute function to be used.
output	The array where the computation results are stored.
vars	A std::span containing pointers to the variables involved in the computation.
extraArgs	An optional std::span containing extra double values that may participate in the computation.
