Classes
class	CudaHT::CuckooHashing::CompactingHashTable
	Hash table that provides O(1) translation between keys and unique identifiers. More...
Namespaces
namespace	CudaHT
	Encapsulates the hash table library.
Functions
void	CudaHT::CuckooHashing::CUDAWrapper::ClearTable (const unsigned slots_in_table, const unsigned fill_value, unsigned *d_contents)
	Fills an array with a particular value.
void	CudaHT::CuckooHashing::CUDAWrapper::CallHashBuildCompacting (const int n, const unsigned num_hash_functions, const unsigned *keys, const unsigned table_size, const Functions< 2 > constants_2, const Functions< 3 > constants_3, const Functions< 4 > constants_4, const Functions< 5 > constants_5, const uint2 stash_constants, const unsigned max_iteration_attempts, unsigned *table, unsigned *stash_count, unsigned *failures)
	Calls the compacting cuckoo hash construction kernel.
void	CudaHT::CuckooHashing::CUDAWrapper::CallHashRemoveDuplicates (const unsigned num_hash_functions, const unsigned table_size, const unsigned total_table_size, const Functions< 2 > constants_2, const Functions< 3 > constants_3, const Functions< 4 > constants_4, const Functions< 5 > constants_5, const uint2 stash_constants, unsigned *keys, unsigned *is_unique)
	Removes any duplicate keys from the table.
void	CudaHT::CuckooHashing::CUDAWrapper::CallHashCompactDown (const unsigned table_size, Entry *table_entry, unsigned *unique_keys, const unsigned *table, const unsigned *indices)
	Creates a compacted list of the unique keys and sets up the keys with their unique IDs.
void	CudaHT::CuckooHashing::CUDAWrapper::CallHashRetrieveCompacting (const unsigned n_queries, const unsigned num_hash_functions, const unsigned *keys_in, const unsigned table_size, const Entry *table, const Functions< 2 > constants_2, const Functions< 3 > constants_3, const Functions< 4 > constants_4, const Functions< 5 > constants_5, const uint2 stash_constants, const unsigned stash_count, unsigned *values_out)
	Calls the retrieval kernel.
