compute()

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

overridevirtual

Compute multiple values using optimized functions.

This method creates a Batches object and passes it to the correct compute function. If the configuration requests more than one thread and the batch is large enough, the events are processed in fixed-size chunks by parallel tasks.

Parameters

cfg	Configuration, steering among other things the number of threads.
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.
