I already did some benchmarks with GPU sorting (not in pgsql), and
measured total sort times, copy bandwidth and energy usage, and got
some exciting results:
Was that qsort implementation on CPU cache friendly and optimized for SSE ?
To make a fair comparison you have to take the best CPU

Hello everyone,
I'm implementing a CUDA based sorting on PostgreSQL, and I believe it
can improve the ORDER BY statement performance in 4 to 10 times. I
already have a generic CUDA sort that performs around 10 times
Hi,
this is not exactly a Postgresql question, but an input from hackers
list like this would be invaluable for me.
I am coding my own database engine, and I decided to do not implement
transaction engine because it implies too much code.
But to achieve the Durability of ACID I need a 100%
