inlineoverridevirtual

Compute multiple values using cuda kernels.

Compute multiple values using optimized functions.

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.

This method creates a Batches object and passes it to the correct compute function. In case Implicit Multithreading is enabled, the events to be processed are equally divided among the tasks to be generated and computed in parallel.

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.
