nvbio::cuda::WorkQueue< MultiPassQueueTag, WorkUnitT, BLOCKDIM > Struct Template Reference

Detailed description

template< typename WorkUnitT, uint32 BLOCKDIM>
struct nvbio::cuda::WorkQueue< MultiPassQueueTag, WorkUnitT, BLOCKDIM >

Implements a multi-pass WorkQueue that uses thrust::copy_if to compact continuations between kernel launches (see Work-Queues). Mantains input ordering in the thread assignment, hence mantaining memory access coherence, but has potentially much higher overhead than the Ordered queue if the queue capacity is low. High continuation overhead at low queue capacities. At high queue capacities (e.g. millions of elements), the kernel launch overheads are amortized.
