I think it's a huge code task.
You cannot start processing page 500 before you know where page 499 wil end. TeX is not really a kind of application where you would gain a lot by parallelization. And honestly, I don't remember seing many applications using both cores. (Plus: I'm happy if other applications continue to run smoothly instead of being blocked by TeX using 95% of both processors.) > It could be useful for offering typesetting services.

If you would offer a service, you would get multiple requests at the same time anyway, so there's no real need for that in this case (you'll face many more serious problems when offering typesetting service). > Joking, perhaps you could fix it in Mark VII ;-) You can try XeTeX if you want to put load on both processors. It does offer a parallel process as far as I heard, but then you'll probably want support for quad-core once you get a better computer :) Mojca ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
