Why Don't Open Source Databases Use GPUs?

[sl4shd0t]

An anonymous reader writes "A recent paper from Georgia Tech (abstract, paper itself) describes a system than can run the complete TPC-H benchmark suite on an NVIDIA Titan card, at a 7x speedup over a commercial database running on a 32-core Amazon EC2 node, and a 68x speedup over a single core Xeon. A previous story described an MIT project that achieved similar speedups. There has been a steady trickle of work on GPU-accelerated database systems for several years, but it doesn't seem like any code has made it into Open Source databases like MonetDB, MySQL, CouchDB, etc. Why not? Many queries that I write are simpler than TPC-H, so what's holding them back?" http://a.fsdn.com/sd/twitter_icon_large.png (http://twitter.com/home?status=Why+Don't+Open+Source+Databases+Use+GP Us%3F%3A+http%3A%2F%2Fbit.ly%2FK3eETf) http://a.fsdn.com/sd/facebook_icon_large.png (http://www.facebook.com/sharer.php?u=http%3A%2F%2Fdevelopers.slashdot.org% 2Fstory%2F13%2F12%2F25%2F1327216%2Fwhy-dont-open-source-databases-use-gpus%3Futm_source%3Dslashdot%26utm_medium%3Dfacebo ok) http://www.gstatic.com/images/icons/gplus-16.png (http://plus.google.com/share?url=http://developers.slashdot.org/story/13/12/25/1327216/why-dont-open-source-databases-use-gpus?utm_source=slashdot&utm_medium=googleplus)
