My internet has a download limit of 10gig/month and I have to pay for excess usage. In the last 2 weeks I added 4 more PC's to the nerwork (almost doubling it) and this month I exceeded our limit and it will cost me a bit. A full month of usage at the current rate will cost me a fortune.

I've noticed that for a ~2 hour WU, Einstein@home downloads 2+ ~3meg files & uploads a similar size file (uploads count towards my cap as well ). I'm going to have to drop Einstein on the work PC's to save me money, but does anyone know if any of my other projects (listed below) may be a problem with regards to download/hour of processing?

Changing my intenet isn't an easy option as it is paid for by the government and it has to meet fairly strict requirements to be covered by their funding.


I am attached to Seti@Home, Einstein@Home, Docking, climateprediction.net, Cosmology@Home, Poem@Home, Milkyway@home, rosetta@home, DrugDiscovery, boincsimap, malariacontrol.net, lhcathome & orbit@home.

Thanks in advance for any help you are able to give.

Well, I'd say that CPDN is probably the best for downloads since the WUs take such a long time. You might also try cutting down on the number of projects you're attached to, so you don't have as much traffic checking in with all of them.

That's only true for the ABP tasks, which you can deselect in the project preferences.

The S5 tasks (the other type) download the application once (of course) and some (quite big) data files that then are used for multiple tasks. I'm not quite sure, but I think the uploaded size isn't that big either.

Considering the number of MB per day per 2 CPUs, using Honza's data, of these, Milkyway seems to be the least bandwidth-hungry, with Einstein coming at a distant second. It's also clear that Rosetta and Docking are the worst offenders.

Wow - Fantastic info. I would have been in trouble at the end of the month again without it. (Particularly since stopping Einstein would have increase how much Docking & Rosetta was being done)

Cheers!

Hmmm...Just turned Einstein@home off again. I restarted it and one PC downloaded 28-30 3.5-4meg files for a 6hr task! Thats 1% of my monthly quota gone for that 1 task on one PC!!

I went to the Einstein options but you cannot deselect the application (one of the Global Correlations S5 Engineering apps) as the tick box is greyed out. I've set Docking, Rosetta, Einstein & BoincSimap to no new tasks and i'll see how this month goes.

Thanks all

The S5 tasks work with locality scheduling. That means those data files are downloaded once for multiple tasks. With any luck, they'd last a whole month!

PS: The newest (development) BOINC clients have the new feature of user-selectable download quota. That might be interesting for you.
