CEP by Apache Mahout via the Google MapReduce Framework

Tim Bass

MapReduce is a software framework implemented in C++ with interfaces in Python and Java introduced by Google to support parallel computations over large (multiple petabyte) data sets on clusters of computers.* The Apache* Hadoop project is a free open source Java MapReduce implementation.* Mahout is an Apache project, based on Hadoop, with an objective to build scalable, Apache-licensed machine learning libraries.

The Mahout team is initially focused on building the ten machine learning libraries detailed in Map-Reduce for Machine Learning on Multicore by seven members of Stanford’s computer science department.** These libraries, some, if not all, critical for “real” complex event processing, include;

Locally Weighted Linear Regression (LWLR),
Naive Bayes (NB),
Gaussian Discriminative Analysis (GDA),
k-means,
Logistic Regression (LR),
Neural Network (NN),
Principal Components Analysis (PCA),
Independent Component Analysis (ICA),
Expectation Maximization (EM), and
Support Vector Machine (SVM)

Ready to move beyond rules and rule-based systems to process complex events? Interested folks should visit the Apache Mahout Wiki.

httppower(8)							     powerman							      httppower(8)

NAME

       httppower - communicate with HTTP based power distribution units

SYNOPSIS

       httppower [--url URL]

DESCRIPTION

       httppower  is  a  helper program for powerman which enables it to communicate with HTTP based power distribution units.	It is run interac-
       tively by the powerman daemon.

OPTIONS

       -u, --url URL
	      Set the base URL.

INTERACTIVE COMMANDS

       The following commands are accepted at the httppower> prompt:

       auth user:pass
	      Authenticate to the base URL with specified user and password, using ``basic'' HTTP authentication which sends the user and password
	      over the network in plain text.

       seturl URL
	      Set the base URL.  Overrides the command line option.

       get [URL-suffix]
	      Send an HTTP GET to the base URL with the optional URL-suffix appended.

       post [URL-suffix] key=val[&key=val]...
	      Send an HTTP POST to the base URL with the optional URL-suffix appended, and key-value pairs as argument.

FILES

       /usr/sbin/httppower
       /etc/powerman/powerman.conf

ORIGIN

       PowerMan was originally developed by Andrew Uselton on LLNL's Linux clusters.  This software is open source and distributed under the terms
       of the GNU GPL.
