Well. If you have studied the archives then you also know that t...@h is slightly past its zenith. t...@h has a good infrastructure but unfortunately 95% of the computing power we collect with that infrastructure is wasted through the very inefficient algorithms we use to get from data to tiles. The sad thing is that for most tiles, computing them centrally with fast software takes less time than the overhead of creating a job, sending it to a client, and accepting a tile upload later.
I'm using BOINC, too, and I stumbled across a post proposing to move tah onto the BOINC platform. I read threads from 2008, 2009 and 2010. This great idea is mentioned several times, everybody says: "Great idea, I would like to see that". Will this story never end? Are there any problems that stop this move? Or does nobody want to have TaH running on BOINC?
I guess nobody wants to code it. I'm unsure if the complex requirements of a t...@h client (including Inkscape, proper fonts, Perl & all) can simply be thrown at the boinc wrapper script; my guess is that one would have to write quite a bit of code to allow something like inkscape to simply and seamlessly suspend and continue in BOINC environment.
I haven't found any answers yet, so I posted here.
I'd say: Set it up, try it out, and report back with results ;) Bye Frederik _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/listinfo/tilesathome
