DescriptionThe HPC landscape has undergone a lot of changes in the past years. In addition to more heterogeneous system architectures, a wealth of novel workloads specifically from the data sciences have emerged. With these novel workloads, a broader user base with different workflows and expectations about interactivity have arrived. In addition, traditional HPC applications have embraced more interactive workflows. The goal of this BoF is to bring together domain scientists, tool developers and HPC center administrators to identify the scientific impact and technical challenges of highly interactive access to HPC resources.
