Task-based Execution Visualization

One of the purpose of task-based programming is to let asynchronous execution achieve extreme pipelining of operations. This however make it a real challenge to determine why an execution performs poorly, since the execution trace shows the mixture of unrelated tasks. With the the University of Grenoble, we have designed a visualization framework which allows to easily visualize different metrics of the execution trace and apply different techniques to reveal the execution behavior. This allowed to determine and fix some erratic behaviors for instance in the StarPU runtime system and OpenMPI communication library [13], [4]
