Abstract

Scientific computation increasingly consists of a workflow of interrelated tasks. Containerization can make workflow systems more manageable, reproducible, and portable, but containers can impede communication due to their focus on encapsulation. In some circumstances, shared-memory regions are an effective way to improve performance of workflows; however sharing memory between containerized workflow tasks is difficult. In this work, we have created a software library called Dhmem that manages shared memory between workflow tasks in separate containers, with minimal code change and performance overhead. Instead of all code being in the same container, Dhmem allows a separate container for each workflow task to be constructed completely independently. Dhmem enables additional functionality: easy integration in existing workflow systems, communication configuration at runtime based on the environment, and scalable performance.
