3D visualization of HPC Tasks Scheduling Algorithm
Abstract:
The paper is devoted to the issue of visualization of the algorithm for scheduling parallel tasks. Task planning is a key part of the online visualization and parallel programming environment developed by the author. When programming a parallel version of one application task, a suspicion arose that the scheduling algorithm does not optimally distribute the load between the performers. 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 display view works in three-dimensional space and visualizes the assignment of tasks with dots. The coordinates of the points are determined by the logical time, the sequence number of the core (performer), and the sequence number of the data block from the decomposition of the task. The color of the dots is set by the task type. Dependencies between data tasks are shown in segments. The constructed view of the display successfully coped with the task, and the planning algorithm was improved.
