    Beyond is right, you can set up a proxy, sorry, forgot about it.

    If Mr. Barnes continues to have problems connecting I'll back off the rally, with 60-70 cores running I'm afraid I am flooding the server with connection request.

    He can run the manual LLR, and you?

    I pull out 6 cores from LLRnet (now manual LLR'ng the lower ranges), at least the connection is free from here to the world.

  6. #166
    I could, but I won't. Too much work involved and too many machines, I do not use the manual LLR on my personnal prime searches, just llrnet.

    I cut-off access to your server from my end....will wait till the cache is drained brfore reconnecting.

    Please keep your machines online, at NPLB forum we are trying to pull out a few cores to free up the connection for you.

    Carlos, just now uploading 4000+ results. I will attempt to download 15000+ tests to keep the machines crunching thru the night.

    Ok.

  10. #170
    It did not work out, was unable to grab that many tests. Probably a good thing. I have been unable to get everything connecting to my proxy, it's being overloaded and dropping connections too.

    I've pulled a few machines off to see if the proxy can catch up. If that works fine, if not that is fine too, I'm tired of messing with them, I've had enough for one day.

    I think the best bet for the next time is to reserve several large ranges and split them between several llrnet servers running on my systems.

    It was a good try Carlos, but your server is down again. I have 2000+ results (as of now) ready to upload when you come back online.

    Ok, going to try to get a proxy server running.
    If all works out well, I may open it to the outside.

  13. #173
    Well I'm completely out of work, but still a boat load of results to be uploaded. Going to bed and will worry about it tomorrow.

    It's spotty at best. I got lucky, managed to get my proxy server up (thanks!) and snagged 100 just to keep my 8 cores busy for a little bit and see how it works out.
    I have 4gb of ram so that's a non-issue.
    Now Carlos can't blame me for crashing his port 100 server

    19c2c462 is you Beyond, must be one of your clients, I suspect the proxy server...lol
    We need to find a way to minimize the traffic load...

    Yep, your own llrnet server. Then you can send the results to Karsten and he will parse them to see if all candidates were tested or not.

    It's Alive! Work is flowing again.

    Hang in there Carlos, we will get the lower ranges knocked out.

    I'm trying hard...since my 6 am to 8 am I rebooted the server several times, then I gave up until 9 am, went to bed instead. When I woke up I managed to turn it up again when you turned off your machines...lol

    I was trying to just start up a few at a time to keep from flooding the server this morning. It does not seem to be working. even though I got a bunch of results uploaded and a few tests downloaded it has locked up again.

    I'm going to clear the caches on all the clients while I have access cut off to your server, then shut the clients down. At that point I will open access to your server again to upload the results.

    Sorry for all the problems caused, I would have never dreamed llrnet could not handle the load.

    Beyond,

    Tnerual pointed me something useful that I though I already had. Microsoft introduced Win XP SP2 and limited the number of possible TCP connection attempts per second to 10 (from unlimited in SP1). I applied http://www.lvllord.de/ patch and increased that number to 100.
    More info in here.

    I hope now the server can handle more connections per second. It's XP SP2 limitation and not llrnet one.

    Carlos

    That is good to know. It seems to be working now. I will give it a while before ramping back up. I'm sure you realize that the higher we go in "n" value the less the load will be on the server connections, it is just a matter of time and all will smooth out.

    I wasn't here but the server went down from 18:51 to 20:03 and got up by itself...

    Yes, as n goes high the number gets larger and so more time is needed to process and therefore less communications between clients/server.

    maybe it was the "pruning" job ... if llrnet is at a higher priority than llrserver, pruning job is going very slowly and server appears off during the whole time.

    how to check that ? take a look at the knpairs.txt details (last modification time)

    if time of knpairs.txt is around 20:03, increase priority of llrserver
