Just wondering about the size of the data files download and uploaded by BOINC.. I don\\\'t have an unlimited internet connection..

The program lets you limit bandwidth(speed), but not a data limit.

Any one able to give a weekly or monthly estimate??

@Matt From AU

I probably can\'t give you a good estimate, because the availability of WUs has been so sporadic and I don\'t micromanage my project files, but...

My AMD Turion 64 X2 Mobile Technology TL-60 (2GHz, 2MB RAM, Vista) Laptop, with an air-card (1xEVDO, wireless dial up) connection, has just downloaded 12 WUs of 248 KB each sitting on as I type. I\'ve had a few others earlier today, too.

As to the downloads, you can control the amount of data you receive from any project by the settings under \'Advanced/Preferences/network usage/\' \'Connect about every x.xxxx days\' and \'Additional work buffer x.xx days (max. 10)\', especially the latter. Keep it small, say two days or less, and you should be able to keep your data transfers small. My recommendation, \'Connect about every 0.5000 days\' and \'Additional work buffer 2.00 days (max. 10)\', YMMV.

There are similar setting under your account for each project.

You can also control when you connect by \'Activity/Network activity suspended\' to stop it and \'Activity/Network activity always available\' or \'Activity/Network activity based on preferences\'. I tend to manage BOINCs connections because I\'m not always online. I find it somewhat annoying to have BOINC keep trying to connect when I\'m not online. I change from \"suspended\" when I\'m not dialed in, to \"always available\" when I am.

BTW, a lot of the errors you will see in the message log seem to be server-side or network related errors. There isnt anything you can do about them so, unlike some people, don\'t come unglued. They\'ll get fixed eventually.

A number of issues I\'ve been having with LHC in the last day or so seem to be bandwidth/network congestion problems. It\'s getting better. I suspect LHC was hammered pretty hard yesterday when they started testing. BOINC/LHC was having problems uploading/reporting, Firefox couldn\'t connect to the web server because of timeouts, and I could barely get an RSS feed through.

Hope, this helps a bit...

Cheers,

Stephen

PS These must be good runs, one almost 3 hours and not 50% through, and the other about 2:15 and only about 33% through. These beams are not spinning out as quickly as some I\'ve see (2 seconds and finished) that must have gone straight out the wall from the injector. <GRIN>
