'ko'? Is this a typo? And sending where?

do you mean timesteps?

here's a quote from the FAQ:
"A timestep represents a 1/2 hour of model time (not realtime).
Every 10,802 timesteps your model will trickle (report), and there are 24 trickles in a phase.
When you know that a model year is 12 months of 30 days (not 365 days),
you can work out that a phase is 15 years 1 day of model time (not realtime).
Each model is comprised of 3 phases."

"Here's some rough performance numbers for a reasonably quick P4, using 1 logical cpu:


Timestep = 2.2 Seconds
Trickle = 6.6 Hours
Phase = 6.6 Days
Model = 19.8 Days"

Note - all the above is quoted from the FAQ

Hi,
In French KO (Kilo octets) is KB (KiloBytes)
But, I don't understand the question...:o)
Perhaps, it's : "how many KB CPDN is writing on the disk each second, or computing each second...?"

Haha sorry I wrote this really quickly, I will ask again in a more proper maner. How many kilobytes(kb) is the program sending(uploading) from my computer on the internet per seconds? I had an horrible internet bill last month and I am trying to find the source. I wish I had unlimited upload. I had like over 30 gigabyte excess... and the thing is that I have anti-virus and anti-trojan and nothing has been detected.

I think I can reassure you. CPDN is one of the least demanding distributed computing programs from this point of view.

Each regular trickle is tiny (just a few bytes). The trickle at the end of phase 1 and 2 is bigger, but not large. The only time you use significant bandwidth is at the end of the run, when the upload is about 7MB, but in your case that would be once every couple of months. So I don't think CPDN can be the culprit.

Hi Julien,
A trickle on my computer is 91 bytes, and I upload 4 a day (HT, 2 virtual processors).
About every 5 weeks each 'processor' uploads about 7 megabytes of data.

I use AdAware, SpyBot, AVG, (a virus checker), and on one occassion, (so far, touch wood), HighjackThis.
The later found 5 trojans; 3 of one type and 2 others.

Your problem sounds like one of those hidden programs used to take over a computer and make it send spam.
I'm not sure how they are classed: Trojan? HighjackThis should find it, but the results need to be used CAREFULLY.
It just lists files it finds; they may well be OK.
When I ran it, it included BOINC in it's list!
I'm using pre-paid dialup, so they wouldn't get too far before I found out.

Two days ago, I got an email from "e-bay", saying my details needed to be updated, and to fill
out a form. As if! Obviously a "phishing expedition", as I've never even looked at the site.
Yesterday I got a "Nigerian letter".
These are the first con jobs I've had since I switched ISPs 2 years ago.

Les

edit
Sorry Andrew, I was a bit verbose, and you got there first.

Hi Julien

When you say 'anti-trojan', do you mean a firewall? Your firewall should be checking movement in and out, and you should be able to look at its datalog to see what it has been rejecting.

Make your anti-virus run an internal system check. Update your anti-virus and firewall every week.

Download and install Spybot and Adaware. Update and run them regularly, at least monthly. I think it's safe to let them delete everything they find, but look at the list first, just in case.

Update your Windows (or other)internet browser regularly. There were critical updates for my windows system last week.

Disconnect your internet connection when you're not using it until you've discovered the problem.

Have a look at Task Manager (right-click on the clock at the bottom right of your screen) to see what applications and processes are installed and running.
