TPC-W

TPC-W is a standard benchmark that models an online bookstore. We provide a J2EE server and a Java client implementation, which are interoperable.

• tpcw-nyu-uva.tar.gz: Source code of the J2EE TPC-W benchmark server implementation. This version is based on the implementation from New York University. For instructions, see 'docs/README.TXT'.
• tpcw-nyu-uva.patch.gz: This patch contains the differences from the original TPC-W-NYU (2004) distribution. Please note that the NYU link above no longer provides this version, only a newer (2005) one. This patch was not tested against the newer version and may require changes. However, it may already contain the key improvements found in the newer version.
• tpcw.ear.gz: For convenience, this file contains the TPC-W J2EE server binaries compiled from the above source code. It is ready to drop in an application server like JBoss 3.2.7. The sources were compiled for JVM version 1.5. Please note, you still have to populate the TPC-W database (see 'docs/README.TXT' in the source), and that this does not include the necessary image files (see download below, or refer to the original TPC-W-NYU sources).
• tpcw-nyu-static.tar.gz: Prepared static web content files (images) for the TPC-W server. This includes buttons and 1000 item images and their thumbnails. If using a dedicated HTTP server (e.g. Apache 2 with mod_jk 1.2), place the contents in its web serving directory (document root), and make sure to set up forwarding to the application server such that requests for images are not forwarded. Or alternatively, the contents of the 'www/tpcw' directory can be copied into the 'docroot' directory in the server source tree before compilation, in order to be included in the final EAR file and be served by the application server.
• tpcw-uva-client.tar.gz: Source code for the TPC-W Java client. This version is based on the implementation from the University of Wisconsin, modified to interoperate with our server code above. The 'rbe' subdirectory contains the modified client. (The other directories are not used.) See 'rbe/README' for instructions.

Delaydvs

A dynamic voltage scaling solution for multi-tier servers. Includes the main program and an Apache2 module for measuring end-to-end delays, which should be used together.

• delaydvs.tar.gz: The main program sources.
• mod_delaydvs.tar.gz: The Apache2 module (v0.12) sources.

ClusterControlWare

A general power and performance control middleware for multi-tier server clusters.

• ccware-1.0.tar.gz: Source code for the middleware in Python. See README file for instructions.
• cluster-conf.tar.gz: Supporting package, containing cluster configuration files and various server control scripts.
• mod_delaydvs.tar.gz: Optional Apache2 module (v0.14) sources. This is only needed for request latency feedback from an Apache Web Server.
