Comparison Sputnik vs. JPPF

The projects in this folder where resurrected for comparing Sputnik with JPPF using the feature selection application. The projects in this folder have been an early prototype for Sputnik based on JPPF. It is not recommended to use them for anything else apart from the experiment comparing the runtimes of the feature selection application using Sputnik and JPPF.

Comparison experiment with JPPF

The setup of JPPF-based implementation is more complicated since it has only been an early prototype which was abandoned in favor of Sputnik.

Build

As the first step all projects must be built via the build-all.sh.

$ ./build-all.sh

Deployment

This description assumes that [key-based SSH authentication}(../../doc/SSH.md) is set up already. Then you have to startup a REPL in the project jppfnik-control via leiningen.

$ cd jppfnik-control
$ lein repl
jppfnik-control.main=> (require 'jppfnik-control.launch)
jppfnik-control.main=> (in-ns 'jppfnik-control.launch)
jppfnik-control.launch=> (launch "resources/example_config.clj" :start-client false :deploy-client false)

After that the server and the workers are running on the machines specified in example_config.clj. Additionally, there is a folder jppfnik-control/sputnik-payload with all needed files to run the server, the workers or the client application.

Run feature selection

Switch to the folder jppfnik-control/sputnik-payload which has been created in the previous deployment step.

$ cd sputnik-payload

In that folder you can run the runtime experiment with the feature selection application via:

$ java -cp jppfnik-client-0.0.1-standalone.jar:clojure-1.6.0.jar:feature-selection-jppf-0.0.1.jar \
-Dlog4j.configuration=log4j.properties -Djava.util.logging.config.file=logging.properties \
feature_selection_jppf.main run west.csv --folds west_folds.txt \
--one-probability 0.01 --flip-one-probability 0.5 --flip-zero-probability 0.5 --crossover-probability 0.01 \
--keep-best 0.005 --population-size 10000 --generations 5 --rescale-factor 4 --seed 4711 \ 
--client-config jppfnik-client-<MACHINE>.properties --mode distributed --batch-size 5 --progress --quiet

The placeholder <MACHINE> refers to the machine name that is specified for the client application in the ``example_config.clj```.

Running the experiment with the modified calculation runtimes is possible by adding the options --sleep-duration <SLEEP> --sleep-frequency 5 where <SLEEP> is the sleep duration in milliseconds.
