Bro's,

Elite Fitness will be down periodically Friday morning between 4AM and 7AM. We are adding more servers to make the site faster. I appreciate your patience and support during this interruption in service. The following sites will not be affected.

www.EliteFitnessNutrition.com
www.EliteFitnessDating.com
 
So, what kinda machines are you adding?
Is this a cluster or just a load balanced farm?

I don't think a cluster would make sense for this type of site.

It would make more sense to load balance it and separate the databases out. Say the chat and the AS boards are the two most popular, then separate their databases and put those on different manchines - same with the webservers.

Fewer issues with time synch that way - but it looks liek that might be resolved now anyway.
 
They USED to run it on a sun box.
THen switched to Dead Hat.

I'm sure it's a balanced farm of dead hat machines.

faster is better...

what is the reason for the increased load???

is it increased posting and more members or does it
hinge on the actual volume of posts contained in the database?

It is a colocated service, so they are run on what is available at the right price I imagine. I have no issues with RedHat.

I'm a SuSe and FreeBSD kinda guy.

I've never used SuSe I don't think - I always think of it as the Euro distro. I've heard good things about its package management system.

I have FreeBSD on my Stateside server and it does just dandy. Good with threads or something. For what I do it would be just as fine being a Linux box of any flavor.

When I was running a distributed cluster in my apartment, it was easiest to setup with open source code on a RedHat system since that was what the people that wrote it were using - but with work and effort one could port it to other *nix fairly easily I imagine.
That is beyond my interest level.

I like stocks and coding to analyze them - I don't care about programming a better distributed system client/master.
 
Yast is a good pkg management tool.
Were you using Scyld for clustering?

Nope. I considered writing my own program to sit and monitor a port and do the work. I also considered a Beowulf. But then I read about OpenMosix and saw the tools that were available - that combined with ForkManager the Perl module was enough for me.

I have a C program that analyzes a crapload of stuff in about a second (.75 of a second on an athlon 2200+). I then had a Perl script that would iterate over the data and pass the data into a call to the C program via the command line - this was done via a fork.
That spawns a process and as it does that, many of them build up and the OpenMosix system sees the load increase on the mother node, so it feeds it off over the network to a random node that isn't busy. If things are busy, it will put it into a wait state (which didn't happen much due to the pacing of it all).

In the end, it helped me get through a lot of data a lot faster.

I have since changed the analysis style a bit and I'm able to get a way with a lot of well written Perl to do the analysis fast enough.
I just recently learned about how nice Memoize is if you broke up your code into functions properly.
 
Did you find Mosix easy to set up?

OpenMosix - Mosix is something closed and you have to pay for. I think it is Moshe Barr (sp?), and Israeli programmer that has done the bulk of that code.

Yes, it was easy to setup from what I recall - which is embarrassingly little now that I'm trying to pull it up in my head. I had a very hard time at first because I was purposely loading a very stripped down version of RedHat onto the machines and several times made it too stripped down to be useful.

There are a few CD distros that you just put in the CD into the machine and it boots up off of that CD and then everything runs in RAM (on the nodes) and it autodetects the cluster and joins it (which is something the OM does as well).
They even have one for the XBox :)
 
Yeah, I just didn't feel like typing the "open" part.

I didn't know there was elite fitness dating. Too bad there there is only one chick registed in Ontario.

Lol.

Hi Code,

We added more RedHat linux boxes -- we have a small farm of web servers run by an Alteon in front of a beefy database box.

A bit of both -- we are also adding more features.
