Easy Submitting, Intelligent Scheduling and Monitoring Results of Finite Element Jobs with PBS Works

  1. 1. KIRCHHOFF GRUPPEEasy Submitting, Intelligent Scheduling and MonitoringResults of Finite Element Jobs with PBS WorksAuthor: Dirk JunglasCompany: KIRCHHOFF Automotive Deutschland GmbHAm Eckenbach 3057439 AttendornGermanyPhone +492722696554d.junglas@kirchhoff-gruppe.deAbstractIntroduction:PBS Works offers with PBS Professional (a workload management system), Compute Manager and Result Viewer, a smart solutionto submit, monitor and visualize the results of finite element (FE) analysis. With PBS Analytics, also a PBS Works product, it ispossible to analyze the degree of capacity utilization of existing resources. This presentation will show an example how the CAEDepartment of the automotive supplier KIRCHHOFF Automotive optimized workloads on its HPC-Cluster, reduced costs forsoftware and hardware, and increased the productivity of the FE Analyst.Problem Definition:The FE Department of KIRCHHOFF Automotive supports other company departments with finite element analysis. Since the needof computing capacity increased rapidly a HPC-Cluster was installed. The FE analysts are located in different offices at differentlocations and therefore spend a lot of time to organize their jobs on the cluster and idle times on the cluster couldn’t be usedefficiently.Problem Solution:PBS Professional enables the FE Analysts to start their jobs with predefined parameters. The system schedules the jobs on thecluster and gives feedback to the FE Analysts when the job has been finished. At the end of last year PBS Professional wasupgraded with Compute Manager and Result Viewer. Both tools are web based and platform independent and enable the FEAnalysts to submit their jobs, to monitor the state of the job and to visualize the finite element results in a web browser.22.04.2013 1
