Of course that could change if adding a GPU would help Postgres... I would expect it to help mostly for data warehouse batch query type systems, especially ones with very large i/o subsystems that can saturate the memory bus with sequential i/o. "Run your large batch queries twice as fast by adding a $400 part to your $40,000 server" might be a pretty compelling sales pitch :) That said, to help in the case I described you would have to implement the tapesort algorithm on the GPU as well. I expect someone has implemented heaps for CUDA/OpenCL already though. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
