[jira] [Created] (ARROW-2126) [Plasma] Hashing for GPU objects

Philipp Moritz created ARROW-2126:
-------------------------------------

             Summary: [Plasma] Hashing for GPU objects
                 Key: ARROW-2126
                 URL: https://issues.apache.org/jira/browse/ARROW-2126
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Philipp Moritz


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?
