[JPPF v3] "Proportional" Load Balancing Algorithm Question
« on: February 16, 2012, 10:26:53 PM »

Code: [Select]
# Load-balancing algorithm
 jppf.load.balancing.algorithm = proportional

# "proportional" profile
 strategy.proportional_profile.size = 5
 strategy.proportional_profile.performanceCacheSize = 3000
 strategy.proportional_profile.proportionalityFactor = 2
 

Q1) In the above configuration, is the property called "size" or "initialSize". 

I see both used in the Load Balancing and Full Server Configuration (default values) sections of the Configuring a JPPF Server page

Q2) Also, where would I get a listing of all the properties available to each of the pre-packaged load balancer algorithms (or is everything available already listed in the Full Server Configuration (default values) section)?

I tis "initialSize" for the proportional algorithm.

It is in the Load Balancing documentation: by the end of this section, you have a subsection for each built-in algorithm, with all the parameters each of them uses.

Thanks for the reply Laurent,

Is there a description of the properties as well (ie. what they do and how they affect the algorithm?)
For example, I'm not sure what the proportionalityFactor property does when using the proportional Load Balancing algorithm.  Where would I look?

Hello Iced,

For the proportional algorithm, you will find an explanation there: http://www.jppf.org/doc/v2/index.php?title=JPPF_Performance#Deterministic_algorithm:_.22proportional.22_configuration
Please note that this page is pretty much obsolete (in particular the propoerties names are not up to date with JPPF v2.x and v3.x), however the description of the algorithm is still good.
For the other algorithms we don't have much doucmentation about it, and I registered a feature reaquest for this: 3492684 - Detailed documentation of load-balancing algortihms

Sincerely,
