Аннотация:Solving a particular task on a computing cluster forces nodes interaction through a high-speed communication environment. However, even in such network, delays in data transmission happen. Analysis of such delays is extremely im-portant for understanding of the processes taking place in the cluster in more details. Also it can be useful for possible errors detection. We propose a method for delays visualization in the cluster communication environment using stress majorization in the multidimensional scaling method. Method is implemented as a part of the visualising application. The results of experiments on data collected on JUROPA, Lomonosov, Lomonosov-2 super-computers are also provided
