2002 - cesnet

Figure 7.2: Load of CESNET2 during SC2002(both approx. 1/3 of the overall capacity of MetaCentrum, the third biggest useris UK with approx. 1/6 of the overall capacity). On the other hand, MetaCentrumsources are not much used by students and employees of technical universities(particularly ČVUT and VUT). We have focused on this situation in 2002,based on close collaboration with the University of West Bohemia in Plzeň. Wedecided to check the applicability of MetaCentrum (particularly its clusters) forthe solution of significant technical tasks, in order to make use of the outcomefor propagation among the community of users from technical universities.In November and December 2002, we carried out testing of the performanceof MetaCentrum PC clusters, with respect to the application of a CFD softwarepackage FLUENT 6.0 by Fluent International. This product focuses on simulationsin computational mechanics of fluids and some of its parts have alreadybeen used in supercomputers or the network of UNIX stations in a parallel run.This product is now also fully tailored for the PC-Linux platform. After its testing,the installation of PC clusters has been rendered for routine use by otherusers during the first stage, particularly from ZČU Plzeň.Before testing, we had examined – since autumn 2002 – the possibilities of FLU-ENT concerning parallel and distributed run on PC clusters of MetaCentrum.Based on the given knowledge, we made out suitable tasks in collaborationwith Škoda Auto a.s. Mladá Boleslav and NTC ZČU Plzeň. We also obtained, incollaboration with with TechSoft Engineering, s. r. o., a supplier of FLUENT, anunlimited number of licences for FLUENT, valid over a limited period of time102 High-speed National Research Network and its New Applications 2002
