This implementation is completely written in the Java programming
language, making use of the Java Servlet API and the JDBC API for
database connectivity. Running this benchmark requires the use of a
servlet-capable web server as well as a relational database system. We
have tested this implementation with the
IBM
WebSphere ,
Apache/JServ,
Sun Java Web Server, and Jigsaw Web
Servers, as well as the IBM DB2
relational database system.

Architectural Characterization
We are also performing a detailed microarchitectural characterization
of this workload. Preliminary results of our ongoing work were
presented at the 3rd Workshop On Computer Architecture Evaluation Using
Commercial Workloads (CAECW) at the January 2000 HPCA
conference in Toulouse, France.
Here are the presentation slides.

Talk Abstract
The Transaction Processing Performance Council (TPC) is in the process of developing a new benchmark, TPC-W, that attempts to model the application behavior of online web merchant sites. TPC-W consists of a web serving component that models online browsing and purchasing, as well as an on-line transaction processing (OLTP) component that models order processing and tracking. We implement this benchmark based on the preliminary specification that TPC has made available for public review. The remote browser emulation, web merchant application logic, and web server of our version of TPC-W are implemented completely in Java, using the Jigsaw Web Server, the servlet interface for dynamic html and forms processing, and relational database connectivity through the standard JDBC (Java Database Connectivity) interface. The OLTP component is implemented using the IBM DB2 relational database management system.
We characterize our implementation of TPC-W by running it under a full-system simulation environment in a single-tier configuration. Work is in progress to bring up our TPC-W implementation under two different instruction sets (PowerPC and SPARC) running under their respective full-system simulators (SimOS-PPC and SimICS). We will discuss the challenges we faced in bringing up a complex, networked, multitier workload implemented in a new language (Java) on a full system simulator. We will also present preliminary data characterizing the instruction stream, branch predictability, cache behavior, and multiprocessor data sharing patterns of this new workload.
