It looks like some ofthe top10ers are slowing down, as I am up to #8. C'mon guys, give me a challenge. :)

Megadeth, you may have a slight lead, but I am on my way...

Bring it on :) the more competition I have, the better off we are as a team.

Brought my dual P3-S 1.4 GHz system back online today :D

I'm going to be losing some production over the next few weeks as we're selling out house. I don't want to leave my main machine running when the realtor(s) are going through the house. My 2nd node will remain active though...

I am running D2OL on Gentoo Linux, and I am seeing some strange behavior.

For some reason, D2OL opens a new copy of Java every few minutes, without closing other instances. Here is part of my "top" output:

There are so many instance of Java running that they use about 800MB of RAM. That is a bit absurd.

I installed it according to instructions and use this to run it:

screen
./D2OL controller:cli &

(A million copies of Java open with or with screen).

I am using Blackdown:

sheridan temp # java-config -v
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.4.1-01)
Java HotSpot(TM) Client VM (build Blackdown-1.4.1-01, mixed mode)

Has anyone else seen this happen?

How are you running D2OL? Via the terminal, a cron job, or you're own startup script? Who are you running it as (not root I hope) and what perms do you have on your d20l executable and $JAVA_HOME?

I had trouble installing D2OL on W2K3 Server. I had the latest JVM from the Sun website and the install of D2OL would hang when installing the uninstaller. It had also misreported available diskspace a couple screens back ("free space: error" or somesuch). I then downloaded the full D2OL + Java from the www.D2OL.com and the install worked perfectly.

Like Mars suggested it runs as a service through Firedaemon on a PIII 800. It's slow but online 24/24.

I normally run services like this using a script for use in /etc/init.d (sometimes cron), but right now I am in "just make it work" mode and am running it from the terminal. I've tried running it both as a regular user and (when that didn't work) as root, too (yes, I know, I'll repent later :)). There doesn't appear to be any difference in the behavior.

I've tried reinstalling it a few times and changing most settings that looked safe+useful, and have tried running it in file mode. I explicitly disabled the GUI (since this system doesn't have X), but it didn't do anything other than eliminate a "Can't find :0" complaint at startup.

I am fairly baffled as to why this happens on my system and not others, as it doesn't do anything particularly exciting. All stable software, conservative settings, etc.

One possible problem (though unlikely) is that the JVM was compiled with "-march=athlon -O2 -fomit-frame-pointer -pipe". These seem pretty conservative to me though, considering what some Gentoo users use without problems.

Clocker: I'll try the forum you suggested as well, thanks. :)

Just joined myself... about a week ago i think :)

Got only a PIII400 (underclocked 533) cuz its my server and its silent :) but will see if i cant get a faster cpu in it soon...

Have a Celly566 that will do 850... but need a large hs for it.

Setting up a PII-450 also now... and have installed it on my main system too :) Got a 1600+ now but just got my AXP-M 2400+ now and will set up main puter with that one instead. Will have the 1600+ with mobo ready then for 24/7 :)

Well done Mars, you finally made it :D

Meanwhile, I'm finally catching back up after dropping production. Look out photoz and clocker!

Yes, there are JVM free versions at the D2OL downloads page.

It's great to see some new faces in the team! But it's sad that only 50% of the teams nodes are actually producing!! :(

C'mon guys! Revive your nodes! We could double our production!

I don't suppose you're referring to the downloads listed under "Experts Only (No Java Virtual Machine)" are you?

That's simply a distribution that assumes you want to install your own JVM.

I hope you know of a non-Java based distro and will direct me specifically to it.

Hi everyone! I just revived my nodes late last week. I now have 4 boxes crunching. Maybe we should bump this thread often to keep awareness up.

Bottom of the list...oh yeah #105.

I just added my Dual PIII 1GHz machine to the mix. I haven't done any distributed computing in a while. I'm happy to help out SR.

I have a couple of problems though... My current system is soo loud that I have to turn it off to sleep. Doh! Even running my processor Delta's at 7V doesn't help. I need to get some Panaflos for Papsts.

Also, I have two duallie PIII motherboards that are collectiong dust. As soon as I get a few processors, I can get thos up and running. Unfortunatley I have no job so it may be a while.

Anyone looking for a competent computer guy in the Milwaukee area? LOL!

Later,

Ben
