1D performance analysis and tracing of technical and Java applications on the Itanium2 processor

This paper presents a detailed workload characterization of important technical and Java™ applications used in the industry, on the Itanium2 processor. We present a detailed performance study of four major classes of technical applications: 1- Crash finite element analysis (LS-Dyna3D). 2Structural analysis (Nastran). 3- Computational fluid dynamics (Star-CD). 4Other technical applications (GUPS). The performance of technical applications is compared to a commercial Java server benchmark (SPECjbb2000). The data indicate that the average IPC ratio of technical applications to that of the commercial Java application is from 1.23 to 2.36 (1.74 on average). We analyze the time varying behavior of the applications and collect instruction traces at both the kernel and user levels of representative sections of the code.
