Or maybe not. The code above is fine per se, but only tackles the generation phase, there will be later phases. It may be that other parts of http://dlang.org/library/std/parallelism.html used slightly differently would be better for describing more of the problem. taskPool has a lot of interesting capabilities, including parallel reduce which gives a full map–reduce type scatter–gather approach: OP did mention that there was a generation then integration activity overall. Of course, if absolute performance is required things get a bit more tricky avoiding overheads. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
