Wes McKinney commented on ARROW-2126:
-------------------------------------
Should definitely have a CUDA kernel for hashing in {{arrow_gpu}}, it can be
wrapped as a kernel to be applied on {{BinaryArray}} data later

> Key: ARROW-2126
> URL: https://issues.apache.org/jira/browse/ARROW-2126
> Project: Apache Arrow
> Issue Type: Improvement
> Reporter: Philipp Moritz
> Priority: Major
>
> We should have a CUDA function that computes a hash for objects, similar to
> the way it is done for CPU objects at the moment. Is there a fast
> hash/checksum function available for CUDA, similar to xxhash? Maybe this can
> be implemented as a arrow::compute kernel?
