Hi,
I have Intel Core Duo and when I run texexec the CPU resource in gnome is marked about 50%. Is it mean that texexec only use one processor? If it's, can you think to improve it for scalability?
Just a curious question.
Run two jobs at once ;-)
Seriously: no, typesetting (currently) is a single-process streaming task, and that is not easily fixed at all.
Best wishes, Taco
Confirmed so :-) Yes, I understand it's not easy to "fix" it. 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. I'm thinking about having a computation service like alpha.wolfram but with ConTeXt. Like ConTeXt online but benefit from multiple processors....
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
