StreamFlow: Cross-Breeding Cloud With HPC

Workflows are among the most commonly used tools in a variety of execution environments. Many them target specific environment; few make it possible to execute an entire workflow different environments, e.g., Kubernetes and batch clusters. We present novel approach execution, called StreamFlow, that complements graph with declarative description potentially complex makes onto multiple sites not sharing common data space. StreamFlow is then exemplified on bioinformatics pipeline for single-cell transcriptomic analysis workflow.
