<b>Genetic Library</b>
|

<blockquote>
|
||||
The genetic library patch uses a genetic algorithm to tweak the tunables of various schedulers.<br>
|
||||
As workloads change, the algorithm adjusts the tunables to optimize for performance.
|
||||
The patch is very useful for specific workloads that are difficult to tune.

<b>Goal</b>
|
||||
<blockquote>
|
||||
Tuning for workloads is tough, espcially when there are varying workloads. The goal of this patch
|
||||
is that sys-admins and users never have to explicitly tune their system, but have it done autonomically.
|

<b>Currently I have plugins for:</b>
|
||||
<blockquote>
|
||||
<li> Zaphod CPU scheduler
|
||||
</li><li> Anticipatory IO scheduler
|
||||
</li><li> Deadline IO scheduler (currently broken)
|

|
||||
|
||||
<a name="future-work"></a><b>Possible Future work:</b>
|
||||
|
||||
<blockquote>
|
||||
<li> Incorporate pre-defined "sets of tunables". The child's genes would be a set known good of tunable
|
||||
configurations, and the algorithm would just use which ever set performed the best.
|
||||
</li><li> Save optimal tunings for workloads. Recognize changing workloads and switch to optimal settings.
|
||||
</li><li> Make sure genes can be negative.
|
||||
</li><li> Investigate using on packet scheduling.
|
||||
</li><li> Investigate using on SMT scheduler.
|
||||
</li><li> Investigate using Lamarckian Evolution on discrete parameters.

<a name="performance"></a><b>Performance</b>
|
||||
<br>
|
||||
<blockquote>
|
||||
On FFSB there was an average
|
||||
improvement of 9%. On some
|
||||
workloads, I saw a 23%
|
||||
improvement. The only
|
||||
degradation was in sequential
|
||||
read, I saw a less than a 1%.
|
||||
Which was expected since AS is
|
||||
tuned for sequential read.
|
||||
I'll put my formal paper up
|
||||
soon w/ pretty graphics.
|
||||
<br><br>
|
||||
On SpecJBB I've seen about a 1-5% gain on the Zaphod Scheduler plugin.
|
||||
<br><br>
|
||||
On UnixBench I saw about a 2% gain for the file read/write/copy on the Anticipatory Scheduler.
|
||||
<br><br>
|
||||
I've had no luck getting a performance improvement w/ the Deadline scheduler plugin.

<a name="issues"></a><b>Issues</b>
|
||||
<br>
|
||||
<blockquote>
|
||||
Many times there is no IO while a child is running. The child that does not get IO is inadvertenly penalized.<br>

|

<br>
|
||||
<a name="why-kernel"></a><b>Why have it in the kernel?</b>
|
||||
<br>
|
||||
<blockquote>
|
||||
<li>Easier to hook
|
||||
</li><li>Low latency and not have to go inbetween user/kernel (very important for short life cycle)
|
||||
</li><li>Flexibility for the components to use the library
|
||||
</li><li>Might have inconsistent results if was application, because it would be dependent on being scheduled, but itself was
|
||||
in charge of modifying the scheduler. It may set the sched very wrong and never be scheduled.

Subject: [ANNOUNCE 0/4] Genetic-lib version 0.2
|
||||
Date: Tue, 15 Feb 2005 13:29:06 -0600
|
||||
Cc: Peter Williams <pwil3058@bigpond.net.au>
|
||||
Here is the next release of the genetic library based against 2.6.10
|
||||
kernel.
|
||||
|
||||
There were numerous changes from the first release, but the major change
|
||||
in this version is the introduction of phenotypes. A phenotype is a set
|
||||
of genes the affect an observable property. In genetic-library terms,
|
||||
it is a set of genes that will affect a particular fitness measurement.
|
||||
Each phenotype will have a set of children that contain genes that
|
||||
affect a fitness measure.
|
||||
|
||||
Now multiple fitness routines can be ran for each genetic library user.
|
||||
Then depending on the results of a particular fitness measure, the
|
||||
specific genes that directly affect that fitness measure can be
|
||||
modified. This introduces a finer granularity that was missing in the
|
||||
first release of the genetic-library.
|
||||
|
||||
I would like to thank Peter Williams for reworking the Zaphod Scheduler
|
||||
and help designing the phenotypes.
|
||||
|
||||
Some of the other features introduced is shifting the number of
|
||||
mutations depending on how well a phenotype is performing. If the
|
||||
current generation outperformed the previous generation, then the rate
|
||||
of mutation will go down. Conversely if the current generation performed
|
||||
worst then the previous generation, the mutation rate will go up. This
|
||||
mutation rate shift will do two things. When generations are improving,
|
||||
it will reduce the number unnecessary mutations and hone in on the
|
||||
optimal tunables. When a workload drastically changes, the fitness
|
||||
should go way down, and the mutation rate will increase in order to test
|
||||
a greater space of better values quicker. This should decrease the time
|
||||
it takes to adjust to a new workload. There is a limit at 45% of the
|
||||
genes being mutated every generation in order to prevent the mutation
|
||||
rate spiralling out of control.
|
||||
|
||||
SpecJBB and UnixBench are still yielding a 1-3% performance improvement,
|
||||
however (though it's subjective) the interactiveness has had noticeable
|
||||
improvements.
|
||||
|
||||
I have not broke the Anticipatory IO Scheduler down to a fine
|
||||
granularity in phenotypes yet. Any assistance would be greatly
|
||||
appreciated.
|
||||
|
||||
Currently I am hosting this project off of:
|
||||
|
||||
http://kernel.jakem.net
|
||||
|
||||
[1/4 genetic-lib]: This is the base patch for the genetic algorithm.
|
||||
|
||||
[2/4 genetic-io-sched]: The base patch for the IO schedulers to use the
|
||||
genetic library.
|
||||
|
||||
[3/4 genetic-as-sched]: A genetic-lib hooked anticipatory IO scheduler.
|
||||
|
||||
[4/4 genetic-zaphod-cpu-sched]: A hooked zaphod CPU scheduler. Depends
|
||||
on the zaphod-v6.2 patch.
|
||||
|
||||
Thanks,
|
||||
Jake
