Thanks NBIT saves me doing the search to link to them (do you use NBIT ?).


Although to the people that say move elsewhere, I see this post as feedback to the developers as ways to overcome this problem are given.

CPDN is actually not too bad, bandwitdh may look large in the first instance, but since that is pretty much it apart from some small trickles for half a year or so, it's overall negligable ;-)


And then there is the 300 MByte upload at the end...

The classic CPDN used to ask you if it was OK to do this, to allow you to defer the upload to a better time.

I understand that the sulphurs upload at the end of each of five phases - anyone know any better on this? If I am right, any idea of sizes of each of these megatrickles?

If I remember right this change was to offset the impact of the fact that those wu generate even more data that needs to be sent back.

The sulphur I am currently running trickles 24 times each phase. That occurs about every 12 hours on my 2GHz Athlon. I don't know the size though.

you can do it with boinc as well, just disable network access untill a more suitable time

yup, the results of each phase are uploaded at the end of the phase, rather than the end of the model run
i'm not certain of the size, something's telling me it's 3 megs, but that doesn't seem right

If I remember right this change was to offset the impact of the fact that those wu generate even more data that needs to be sent back.

from what i've read, it's also so that the scientists get pliminary results back sooner, so they know if a model is stable or not, if it's not, might as well ditch it (set server state to "over" so it's not sent out again)

it was also so that if a model failed before it completed, the science team at least have partial results for it's run, rather than having to wait for someone to fully complete the model to have any idea how it did

The 'trickles' are small afaik, just an information update.
The Sulphurs are sending at the end of each of each phase (5 in total, don't know about a hughe one at the end, not got that far yet, ask me in a month or 2)
1of5 is 8MB
2of5 is 2MB
3of5 ... will find out ;)

Of course I still havn't sent these in as they get a no header or something error, but I still have about another 10 months till they time oout to figure a way to send them in (the 8MB is causing problem due to it size on dial up and the cut off I get at around 1hr on my 'totaly free' account. I've just found out it does not resume uploads like it does downloads (but they do use decent ZIP compression! :-)

Also, the CPDN team will send out a kill command (on your next connection) if the model goes way off track. They don't just not send it again, they actually stop it and give you a different WU if the one you've got goes bad. Clearly with such a long run time, they don't want to be wasting thousands of hours of CPU time on models that are worthless!

In how many Countries besides Russia do people have to pay by the bandwidth used for there internet access?

Could an ISP there be a bit lax on billing if they knew what you were using tha bandwidth for?

Something that might interest stats fans here

I live in the Channel Islands (Jersey to be precise, no, old Jersey, between England and France)

we only have 2 true ISPs (a 3rd gets it's bandwidth from another) the main one is the telecoms provider (the only one in jersey, it's only 45 square miles)

we've been able to get 2 meg service from day 1 (with 512k and 1 meg as well)
and on the cheapest service, there's a 20GB/month limit

jersey connects to london, and paris

anyone have any ideas why jersey, being a small island, dependant on it's connections to london and paris, can offer such high bandwidth capacity?
