Аннотация

The paper is devoted to the issue of visualization of the algorithm for scheduling parallel tasks. Task scheduling is a key part of the online visualization and parallel programming environment developed by the author. When programming a parallel version of one mathematical application, a suspicion arose that the scheduling algorithm does not optimally distribute the load between the workers. In this connection, it was decided to visualize its work in order to see the overall picture and possible problem areas of the algorithm. The constructed view successfully coped with the problem, and the scheduling algorithm was improved.
