Well, this project is not that specific to PostgreSQL. Everything you need to compile and use Postgres you can find on Wiki or just ask me directly. For starters, I'd recommend to look up some sorting algorithms survey papers from Google Scholar. There is a good paper by Goetz Graefe on sorting, but it either reflects current situation that some future algorithms :) Something on cache-oblivious sorting and on cache http://igoro.com/archive/gallery-of-processor-cache-effects/ Finally, papers referenced in Wiki page about GSoC for this project are a good starting point. As for tests, TPC is kind of ubiquitous, We could just move standard pg_bench script towards more sorting involved.
