HPC workload management for full resource utilization

Summary In industrial HPC applications, the maximization of the overall performance is a complex task: besides optimization aspects strictly related to numerical algorithms, many others must be taken into account. In particular, in addition to single kernel execution, it may be necessary to focus also on workflow execution, as well as it could be important to optimize the execution of a heterogeneous projects workload with dynamically changing priorities. Here we will discuss how we faced this challenge in the context of running large seismic imaging projects.
