Hi all, 1. For those that don't like par_psql (http://github.com/gbb/par_psql), here's an alternative approach that uses the Gnu Parallel command to organise parallelism for queries that take days to run usually. Short script and GIS-focused, but may give you a few ideas about how to parallelise your own code with Gnu Parallel. https://github.com/gbb/fast_map_intersection 2. Also, I gave a talk at FOSS4G Como about these tools, and how to get better performance from your DB with parallelisation. May be helpful to people who are new to parallelisation / multi-core work with postgres. http://graemebell.net/foss4gcomo.pdf Graeme Bell. p.s. (this version of the slides still has a few typos, which will be fixed soon when I get the source ppts back from my colleague's laptop). -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
