DescriptionNext-generation High Energy Physics (HEP) experiments such as those at the High-Luminosity Large Hadron Collider (HL-LHC) and Deep Underground Neutrino Experiments (DUNE) will require significantly more computational resources to analyze orders-of-magnitude higher volumes of data in the next decade. This means that the experiments may need to tap into the large-scale computational resources offered at diverse supercomputing sites traditionally designed for high performance computing (HPC) workloads, instead of the high-throughput computing (HTC) sites HEP experiments are accustomed to. In addition to the challenges of adapting HEP workflows to run on the HPC systems, there are also issues related to authentication/authorization, access policies and reproducibility that need to be addressed. This minisymposium will focus on current status and challenges in developing common interfaces at large-scale computing facilities to enable cross-site workflow portability. Issues such as establishing standardized protocols and tools for data management, workflow execution, and resource allocation will be discussed. We intend to use this minisymposium as a forum to foster conversations and collaborations between the high energy physics and computer science communities towards developing portable workflow execution across computing sites.
