Member Function Documentation

◆ decrementRemainingClients()

void RooFit::NodeInfo::decrementRemainingClients ( )
inline

Check the servers of a node that has been computed and release its resources if they are no longer needed.

Buffers of nodes whose results are copied between host and device (copyAfterEvaluation) must not be released eagerly: their pinned host memory can still be the source of an asynchronous copy that was enqueued on the CUDA stream, and a new owner would overwrite it from the CPU without any stream ordering. Those buffers are released at the beginning of the next evaluation instead, after the stream was synchronized at the end of this one.
