[Ubuntu] SMP Folding Boost - The Kraken installation guide

post #1 of 27
Thread Starter 
Updated to theKraken v.7-pre15

The Kraken is used to increase PPD by reducing TPF by forcing DLB (Dynamic Load Balancing) to come on.
The Kraken "creates synthetic load on every other CPU; said load 'comes and goes' (with certain duty cycle) until DLB is engaged or until deadline is reached (5 minutes by default). 100% success rates have been observed." -tear
Big thanks to tear and Firedfly of [H] for creating this.


This guide is intended for native or VM Ubuntu, it should also work in other Linux distros.

Good guide, but what about the
Code:
thekraken -u

command?
post #3 of 27
Is this just for a 2p/4p system or will this work on a single cpu system?

This is from the original guide over at "H"

*NOTE: To get the most use out of the kraken, you need to have NUMA enabled (SR-2s, other 2p Intel boards) or node interleaving disabled (G34/C32/Socket F AMD systems). If you have a multi-processor board, you should have a bios setting for one or the other.


You guys can get more info about it on the links below. Im not sure it works all the time but its really good to have.

Kraken's job ends the moment FahCore is restarted. Then all bets are off.
You get DLB? Sweet. You don't? Oh poo.

It's best effort approach. That's it. It was never marketed as reliable DLB "enabler".

Quisarious says he didn't see autorestart occur. THAT is worth looking into.

From the same guide above:
Install BFS - for all Intel systems I have tested. NOT for multi-socket AMD systems.

It'll work and MAY benefit any system. TPF decreased have been noted on 1p, 2p, and 4p systems.

I'm all about lowering some tpf but one question. Do you just have to start it up the one time or every time you do a new wu?

You install it and run fah like normal, there's no effort required once it's installed.

Sounds easy enough. Went though the links Desert Rat posted so now I at least understand a little of what it does. Will give this a go when I upgrade my cpu here soon. thumb.gif
