Hi, I\'m new to BOINC & Rosetta and I\'d like to know how large the returned work units are, and how often they get uploaded. I realize that this is probably a highly variable statistic, but a range would be useful.

The reason I\'m asking is that my ISP has a cap on upload bandwidth (5 gig/mo.) and I have been having trouble staying under this limit while running F@H. For this reason I am being forced to abandon F@H and find another distributed computing project that isn\'t quite so bandwidth intensive. The current F@H CVS work units return about 20 mb each, and over a period of a month, this adds up to \"over-my-limit\".

I am currently running an 8-core Mac Pro and a homemade 4-core Q6600 pc.

Thanks for any help!
Pat

With Rosetta, you can select a runtime preference. The longer you let tasks run, the more models they can report in the same outfile. In general they are around 100k each. It would be less for a shorter runtime, but you would have more of them per day.

So, in round numbers, if you ran with the default 3 hours runtime preference and had 100k outfiles (50k more likely), and one task per CPU, running 24x7... you\'d have:

31 days * n CPUs * 8 tasks per day * 100k

I see you have an 8 CPU machine, so this comes out to something on the order of about 200MB for an entire month of uploads with your results. That\'s about 4% of your limit.

Excellent! Thanks, Mod.Sense. It sounds like BOINC & Rosetta are just what I need. As long as no big results files appear suddenly, I\'ll be in good shape.

Thanks again,
Pat
