Function Documentation

BestAvailableBackend()

RooCmdArg BestAvailableBackend ( )

inline

The best RooFit evaluation backend this build supports.

Defaults to CPU, where evaluation is still batched through doEval(). Compiling with -DAU_ROOFIT_BACKEND_CUDA=1, against a ROOT built with CUDA support, switches this to the GPU backend.

Returns

A RooCmdArg to hand to fitTo().

Warning

A downstream project must define the same macro as the prebuilt library, or its call sites will disagree with the library about which backend is in use.
