This paper describes three different porting activities on three parallel applications performed on the new Parsytec GCel-3/1024 Transputer System in Cologne. The communication features of the machine are reported and a brief summary is given on the performance of the ported programs. The three applications differ extremely in computing requirements and parallelization approach: numerical standard algorithms, a TSP-heuristic and the simulation of traffic congestions are examined. In all cases the porting was done in a few days and the gain in performance was very satisfactory even for thousand processors.
