PBS Professional at Chrysler: Efficient Management of 250,000 Simulations Annually

Chrysler, a renowned automotive company, was facing a challenge in managing its growing Computer-Aided Engineering (CAE) server farm. Since the 1980s, Chrysler has been using computer simulation tools for designing cars and trucks. Over the years, the use of computer-aided engineering and finite element analysis expanded, leading to a significant increase in the processor count at Chrysler’s High-Performance Computing (HPC) center. By the late 1990s, Chrysler was building up its HPC capacity to meet the growing demand for CAE simulations by installing a number of servers. Initially, Chrysler used a competitor's product for workload management. However, in 2003, they acquired 384 PBS Professional licenses to manage clusters used exclusively for computational fluid dynamics (CFD) jobs. By 2008, the HPC center was operating 10 servers from a mix of vendors using a variety of Intel and AMD chips running Red Hat or SUSE Linux. The core count on the server farm had increased to 1,544.

Chrysler is a leading automotive company that has been using computer simulation tools since the 1980s for designing cars and trucks. Over the years, the use of computer-aided engineering and finite element analysis has become a crucial enabler for Chrysler designers. The company has a High-Performance Computing (HPC) center with a processor count of 1,544-cores, all managed by PBS Professional. Chrysler runs a variety of simulations including impact simulations, noise, vibration, and harshness studies, and computational fluid dynamics using a variety of commercial packages. The HPC operation is central to the engineering design process as CAE is involved at every stage. The company has 300 CAE engineers worldwide who feed jobs to the HPC resources through PBS Professional.
