Flux: Solving Exascale Workflow and Resource Challenges

" summary

Flux is a next-generation resource and job management system (RJMS) for HPC that can be nested inside batch allocations and other schedulers (e.g., SLURM, MOAB, LSF) to act as per-workflow RJMS instances. The talk explains Flux’s APIs and scheduling approach for non-traditional patterns (co-scheduling, massive ensembles of small jobs, coordinated ensembles) and describes how the Flux-Framework uses open-source processes (C4, RFCs, LGPL and public platforms) to shape its repo structure, collaborations, and team organization.
