Up/download data files sizes

(moderation:
I have a 2GB/month broadband limit. How much of this is Einstein@home likely to consume? Is there any way the BOINC Manager can tell me how much data has been transferred up and down? What size are the download and upload files for a typical work unit?
Up/download data files sizes
)
Hi George,
Welcome to the Einstein@Home project. We hope you enjoy your stay here.
Now that you are over the initial installation, you will probably get a new large data file (~6MB) about every 5 days or so. Say 36MB per month. The results you download are tiny and are essentially "instructions" on how to "carve up" the large data file that you already have until it is "used up". When the crunching is done, a bigger file is uploaded and I have a vague recollection that a finished result might be about 0.5MB or so. If EAH is your only project, the maximum number of results you could do in a month would be about 80 so even if both uploads and downloads were going to count as part of your quota, your monthly use would come to no more than 100-150MB which is well within your 2GB quota.
Please realise that these are "guesstimates" only, but I really don't think you will have much problem.
Cheers,
Gary.

Welcome!
I am using a dial up connection and don't feel a discomfort from loading "the largest files" absolutely. Maximum number of work units per 1 data chunk is about 17*5 = 85. For me really is about 40-50. I am complete a computation for three or four WU's per 24 hours and consequently about 9-12 days per data chunk. In month - about 20 megabytes... Files to upload usually is very small - smaller than 100 kilobytes.
Excuse me please, if my English is not right. :)
Thanks to both for prompt

Thanks to both for prompt answer - should be no problem.

Of course, all you have to do is ask and we will try to help.
It would help if you could give some detail of any messages you are getting in your BOINC Manager messages tab. It would help if you could tell us what things you have already tried.
You seem to have three computers listed although two of those would appear to be duplicate entries for the same machine. In all three results lists, all completed results have errored out with "Client errors". It's quite probable that you might be experiencing the "graphics bug" which is particularly prevalent if you have ATI graphics hardware. Can you tell us what sort of graphics hardware you have on each machine? Can you also tell us if you are trying to use the screensaver or are hitting the "show graphics" function in BOINC Manager?
If so, and as an experiment, could you set your screensaver through windows to "Blank screen" and could you stop using any graphics display functions until we see if your machines are able to successfully complete and upload the work. If that is so and we therefore prove the point, you have two options:-
1. Continue, leaving all graphics functions disabled until the new science app is released, or
2. Upgrade immediately through the link on the front page of the website to the beta science app.
For the history of the beta app in solving graphics related issues, you might like to read through this thread. You need to read most of it to get the full story of what has been happening.
Cheers,
Gary.
