pub struct CudaHashJoin<T: DeviceCopy + KeyAttribute> { /* private fields */ }
Expand description

GPU hash join implemented in CUDA.

See the module documentation above for usage details.

The build and probe_sum methods are simply wrappers for the corresponding implementations in CudaHashJoinable. The wrapping is necessary due to the specialization for each type T. See the documentation of CudaHashJoinable for details.

Implementations

Build a hash table on the GPU.

Probe the hash table on the GPU and sum the payload attribute rows.

This effectively implements the SQL code:

SELECT SUM(s.payload_attr) FROM r JOIN s ON r.join_attr = s.join_attr
