the probleme is that adsl 1 is limited to 8 mb/s (line side)
adsl 2/2+ is able to go up to 28mb/s (line side)

they always have a 100 MB/s ethernet interface at a minimum...

if you use an adsl 1 modem on a 16 mb/s line, there will be a lot of crc error and line will be bad ...

and yes some modem have a gigabit ethernet interface (ex: D-Link DIR-655 N)

Okay, thanks for the correction.

Are you saying, though, that Carlos will probably have a lot of problems unless he upgrades to a newer modem? (I would imagine if that's the case, then his ISP should send him a new modem, provided they gave him the first one.)

i'm bargaining wih carlos to send him a free modem ...

usually what they do in this case is "downgrading the speed to 6 MB" (i work for an ISP company, repair side ...)

Modem accepted. Thank you very much.

Okay, cool. I was planning to generate stats periodically (i.e. whenever you copy off the results file to send to me) with a little Perl script I've got, but if you can do better, by all means do so.

Note: I cleaned out some of the old attachments from this thread that are no longer needed (such as the knpairs.txt files for batches of numbers that LLRnet has already completed). I left in the knpairs files for the current batches, though, in case anyone wants to refer to them to see how far along we are in the current batch.

It will take some time until I figure it out how to do it but meanwhile you can manual generate the stats. As a backup I'll send you by email the current results files I have for both servers. Please check your email.

Rejected numbers are not numbers that have gone past deadline, or have been canceled by the user. Any clue? Probably something to do with the connection or my fault when playing with the server settings.

Here's a few rejected numbers I got so far (only 4):

Code:

user=*****
[01/23/08 10:37:10]
48697*2^416080+1 is not prime.  Res64: FBCCFA6C0ED7F07A  Time : 1281.0 sec.

all behind in the results-file.
while worked on 48697*2^416080+1 i must paused and continued later because only 111s to complete!
but all others quite ok! nothing unnormal.
the higher timings on server result from dataflow over internet, i think.

Hmm, that's odd. I really don't know what they are--maybe you should ask at the Riesel Sieve forum, since they pretty much developed LLRnet?
