and combined into a script without user intervention. As FH Joanneum has
been using CATIA as the standard tool in various lectures since 1999, the nec-

functions tested include loading of models, graphical representation (including
rotation), 2D drafting, changing a parameter and updating the model, creating
an assembly out of CatParts, cutting planes in DMU and clash computation.

General Information
1.1 Introduction At FH Joanneum a benchmark for Catia V (currently R14, Windows version, support for other Catia versions is currently under development) has been under development since December 2005. This benchmark was driven by the industry with special cooperation by the AUDI AG. From the hundreds of Catia functions only a small part had been selected, and combined into a script without user intervention. As FH Joanneum has been using CATIA as the standard tool in various lectures since 1999, the nec-essary models could be selected from the rich pool created by students. The functions tested include loading of models, graphical representation (including rotation), 2D drafting, changing a parameter and updating the model, creating an assembly out of CatParts, cutting planes in DMU and clash computation. The results are written to a log file, and can be analyzed with an Excel sheet that creates suitable graphs and arranges the various results into a number of categories (aka tasks) - namely ”total time”, ”file load”, ”file close”, ”CPU ac-tivity” and ”CPU+graphic activity”. The graphs produced are shown in 2 ways - once using absolute numbers, a second set showing the performance relative to the BEST result (the fastest results is set to 100 The benchmark is available to the public, as are most of the models used. The large assembly used for some tests is available on request. Intel GmbH Germany provided a set of computers. The necessary software was installed on that computers, each computer was benchmarked with our Catia-benchmark and these are the results of our benchmarks.
1.2 Proceeding Each computer was rebooted before each benchmark. Programs such as virus scanners, screen savers, which would falsify the benchmark were (of course) disabled during the benchmark. The computers got a fresh windows installation before the benchmark (either supplied by Intel or by our central IT Services departement).
1.3 Simulation of additional load For the simulation of an addtional CAE application we used a small (OpenMP enabled) C-programm which does some mathematical calculations and used a

lot of memory - the sourcecode is available online.
1.4 Simulated tasks The currently used version of our benchmark consists of the following subtests: drawing - load small Catparts and generate a 2D drafting view Rotate - load small Catparts and rotate them Open/Rotate/Close a complex assembly in Material view mode Modify - load a moderately complex part, change some dimensions and update the part Assembly - create an assembly out of parts

load a pick-up disc, modify and update the drawing DMU section cuts in a complex assembly DMU clash computing in a complex assembly Open/Rotate/Close a complex assembly in Shading view mode

2.2 Installation notes We had problems with our benchmark on the pre-installed Windows XP instal-lation - there was no VBA-Support in Catia available. After a re-installation of Windows XP 32 Bit everything worked fine. The assumption, that the reason for the problems was XP64 was proven wrong later (the benchmark worked on the Supermicro Woodcrest machine (XP64), but we were unable to find the exact reason and benchmarked the machine with XP 32bit.

3.2 Installation notes We expected, that the machine will cause problems, because the benchmark did not work with Windows XP 64 Bit on Sun, but it worked without problems. We also benchmarked the machine later in 32 bit mode, to examine, if there are differences in 32 and 64 bit mode.

8.6 Summary Our benchmarks clearly shows Catia V R14 is a primarily CPU bound appli-cation and profits most from single threaded CPU speed. Modern operating systems like Windows XP allow to run parallel applications in the background - but even if enough free CPU-cores are available, the negative performance impact can be measured. The impact seems nevertheless to be small enough, to make the use of multi socket/cores in a modern CAE/CAD environment a reasonable investment. On Woodcrest we tested both the 32-bit and 64-bit versions of Windows XP Professionals. The runtimes of the benchmark were slightly different, but similar enough that a user won’t notice in day to day work.
